8038068a2a Finally, fix Zstd kernel build on MIPS and RISC-V
Add an implementation of the intrinsics invoked by __builtin_ctz{,ll} and
__builtin_clz{,ll}, and include this compilation unit on platforms that lack
assembly intrinsics for those builtins (MIPS and RISC-V).

Future cleanup work might involve bringing these into a mini libcompiler-rt
for the standalone kernel environment.  Or cleaning up the approach upstream
takes for builtins in standalone environments (or just FreeBSD).  For now,
at least this builds, and doesn't require modifying the vendor code.

78f57a9cde Generalize the gzio API.
We currently use a set of subroutines in kern_gzio.c to perform
compression of user and kernel core dumps. In the interest of adding
support for other compression algorithms (zstd) in this role without
complicating the API consumers, add a simple compressor API which can be
used to select an algorithm.

Also change the (non-default) GZIO kernel option to not enable
compressed user cores by default. It's not clear that such a default
would be desirable with support for multiple algorithms implemented,
and it's inconsistent in that it isn't applied to kernel dumps.

d626b50b9d make SW_WATCHDOG dynamic
Enable the hardclock-based watchdog previously conditional on the
SW_WATCHDOG option whenever hardware watchdogs are not found, and
watchdogd attempts to enable the watchdog. The SW_WATCHDOG option
still causes the sofware watchdog to be enabled even if there is a
hardware watchdog. This does not change the other software-based
watchdog enabled by the --softtimeout option to watchdogd.

Note that the code to reprime the watchdog during kernel core dumps is
no longer conditional on SW_WATCHDOG. I think this was previously a bug.

2d09b07279 Make kernel option KERNVIRTADDR optional, remove it from std.<platform>
files that can use the default value.

It used to be required that the low-order bits of KERNVIRTADDR matched
the low-order bits of the physical load address for all arm platforms.
That hasn't been a requirement for armv6 platforms since FreeBSD 10.
There is no longer any relationship between load addr and KERNVIRTADDR
except that both must be aligned to a 2 MiB boundary.

This change makes the default KERNVIRTADDR value 0xc0000000, and removes the
options from all the platforms that can use the default value.  The default
is now defined in vmparam.h, and that file is now included in a few new
places that reference KERNVIRTADDR, since it may not come in via the
forced-include of opt_global.h on the compile command line.

70f654991a Add support for 64-bit PowerPC kernels to be directly loaded by kexec, which
is used as the bootloader on a number of PPC64 platforms. This involves the
following pieces:
- Making the first instruction a valid kernel entry point, since kexec
  ignores the ELF entry value. This requires a separate section and linker
  magic to prevent the linker from filling the beginning of the section
  with stubs.
- Adding an entry point at 0x60 past the first instruction for systems
  lacking firmware CPU shutdown support (notably PS3).
- Linker script changes to support the above.

from loader(8), the root_rw_mount rcvar, and by using "mount -u[rw] /"
or equivelent on the fly.  This option is being added to provide a way

8d14ca9c99 Introduce bwn(4) support for the bhnd(4) bus.
Currently, bwn(4) relies on the siba_bwn(4) bus driver to provide support
for the on-chip SSB interconnect found in Broadcom's older PCI(e) Wi-Fi
adapters. Non-PCI Wi-Fi adapters, as well as the newer BCMA interconnect
found in post-2009 Broadcom Wi-Fi hardware, are not supported by
siba_bwn(4).

The bhnd(4) bus driver (also used by the FreeBSD/MIPS Broadcom port)
provides a unified kernel interface to a superset of the hardware supported
by siba_bwn; by attaching bwn(4) via bhnd(4), we can support both modern
PCI(e) Wi-Fi devices based on the BCMA backplane interconnect, as well as
Broadcom MIPS WiSoCs that include a D11 MAC core directly attached to their
SSB or BCMA backplane.

This diff introduces opt-in bwn(4) support for bhnd(4) by providing:

 - A small bwn(4) driver subclass, if_bwn_bhnd, that attaches via
   bhnd(4) instead of siba_bwn(4).
 - A bhndb(4)-based PCI host bridge driver, if_bwn_pci, that optionally
   probes at a higher priority than the siba_bwn(4) PCI driver.
 - A set of compatibility shims that perform translation of bwn(4)'s
   siba_bwn function calls into their bhnd(9) API equivalents when bwn(4)
   is attached via a bhnd(4) bus parent. When bwn(4) is attached via
   siba_bwn(4), all siba_bwn function calls are simply passed through to
   their original implementations.

To test bwn(4) with bhnd(4), place the following lines in loader.conf(5):

  hw.bwn_pci.preferred="1"

  if_bwn_pci_load="YES
  bwn_v4_ucode_load="YES"
  bwn_v4_lp_ucode_load="YES"

To verify that bwn(4) is using bhnd(4), you can check dmesg:

  bwn0: <Broadcom 802.11 MAC/PHY/Radio, rev 15> ... on bhnd0

... or devinfo(8):

pcib2
  pci2
    bwn_pci0
      bhndb0
        bhnd0
          bwn0
          ...

bwn(4)/bhnd(4) has been tested for regressions with most chipsets currently
supported by bwn(4), including:

  - BCM4312
  - BCM4318
  - BCM4321

With minimal changes to the DMA code (not included in this commit), I was
also able to test support for newer BCMA devices by bringing up basic
working Wi-Fi on two previously unsupported, BCMA-based N-PHY chipsets:

  - BCM43224
  - BCM43225

Right now I'm using two Raspberry Pi's (2 and 3) to test CloudABI
support for armv6, armv7 and aarch64. It would be nice if I could
restrict this to just a single instance when testing smaller changes.
This is why I'd like to get COMPAT_CLOUDABI32 to work on arm64.

As COMPAT_CLOUDABI32 depends on COMPAT_FREEBSD32, at least for the ELF
loading, this change adds all of the bits necessary to at least build a
kernel with COMPAT_FREEBSD32. All of the machine dependent system calls
are still stubbed out, for the reason that implementations for these are
only useful if actual support for running FreeBSD binaries is added.
This is outside the scope of this work.

4e96bf3a37 bhnd(4): extend the PMU APIs to support bwn(4)
The bwn(4) driver requires a number of extensions to the bhnd(4) PMU
interface to support external configuration of PLLs, LDOs, and other
parameters that require chipset or PHY-specific workarounds.

These changes add support for:

- Writing raw voltage register values to PHY-specific LDO regulator
  registers (required by LP-PHY).
- Enabling/disabling PHY-specific LDOs (required by LP-PHY)
- Writing to arbitrary PMU chipctrl registers (required for common PHY PLL
  reset support).
- Requesting chipset/PLL-specific spurious signal avoidance modes.
- Querying clock frequency and latency.

Additionally, rather than updating legacy PWRCTL support to conform to the
new PMU interface:

- PWRCTL API is now provided by a bhnd_pwrctl_if.m interface.
- Since PWRCTL is only found in older SSB-based chipsets, translation from
  bhnd(4) bus APIs to corresponding PWRCTL operations is now handled
  entirely within the siba(4) driver.
- The PWRCTL-specific host bridge clock gating APIs in bhnd_bus_if.m have
  been lifted out into a standalone bhnd_pwrctl_hostb_if.m interface.

to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

4e421792ec Remove i386 XBOX support.
It is for console presented at 2001 and featuring Pentium III
processor.  Even if any of them are still alive and run FreeBSD, we do
not have any sign of life from their users.  While removing another
dozens of #ifdefs from the i386 sources reduces the aversion from
looking at the code and improves the platform vitality.

c3191c2e2b Update the mlx4 core and mlx4en(4) modules towards Linux v4.9.
Background:
The coming ibcore update forces an update of mlx4ib(4) which in turn requires
an updated mlx4 core module. This also affects the mlx4en(4) module because
commonly used APIs are updated. This commit is a middle step updating the
mlx4 modules towards the new ibcore.

This change contains no major new features.

Changes in mlx4:
  a) Improved error handling when mlx4 PCI devices are
  detached inside VMs.
  b) Major update of codebase towards Linux 4.9.

Changes in mlx4ib(4):
  a) Minimal changes needed in order to compile using the
  updated mlx4 core APIs.

Changes in mlx4en(4):
  a) Update flow steering code in mlx4en to use new APIs for
  registering MAC addresses and IP addresses.
  b) Update all statistics counters to be 64-bit.
  c) Minimal changes needed in order to compile using the
  updated mlx4 core APIs.

809cd50ff5 Add Freescale QorIQ SATA controller support.
The Freescale SATA controller has many similarities to AHCI controllers, so
this driver is a heavily modified AHCI driver.  Currently it seems to only
do SATA 1.0 speeds (~100-150MB/s), so there is still room for improvement.

Still to be done:
* Address erratum SATA-A-006187 -- Spread Spectrum Support (intermittent
  non-recoverable transient data integrity error seen when SSC enabled).
* Linux doesn't read the log page as it hangs on the P1022.  See if that's
  applicable to this, and address accordingly.
* Try to determine what's holding back performance, and address it.

NO_OBJ has a very specific meaning in sub-directories in that no object
directory will be made.  If a user wanted to skip the 'make obj' phase then
passing -DNO_OBJ would break all sub-directories from building properly.  Using
NO_OBJ internally also causes issue with NO_OBJ handling being added in

- Fixed traffic rate limiting for smaller traffic rate value.

ETH:
- Fixed 40G link failure when interface is toggled.
- Fixed adapter crash when interface is toggled during traffic.
- Fixed 25G link failure when PEER only supports consortium mode autoneg
  for 25G.
- Fixed 100G optics link failure when cable is plugged in after bringing up
  the interface.
- Enable RS FEC as default if speed is 100G.
- Fixed DCBX configuration refresh failure.

================================================================================
Version : 1.16.59.0
Date    : 09/05/2017
================================================================================

FIXES
-----

BASE:
- Fixed fw crash caused by MC parity error in SO adapters.
- Generate Timer0Int interrupt if fw crashes due to unaligned access error. Host
  driver must look into PCIE_FW register to see if any fw fatal error has
  encountered. If PCIE_FW doesn't indicate any error then driver must ignore this
  interrupt.

  receive side.

ETH:
- Fixed an issue in connection traffic shaping when
  FLOWC_WR->FW_FLOWC_MNEM_SCHEDCLASS is not received in first WR on the connection.
- Fixed link failure when speed is changed from 10G-1G-10G due to incorrect flag
  check.
- Fixed improper LED behaviour for blink test and when traffic is running.
- Removed storage of previous fec settings from fw. Driver needs to pass the user
  settings whenever a new module is plugged in as fw resets these when a module is
  unplugged.

OFLD
- OVS offload: TP cache is flushed periodically to get the accuate filters stats
  (hit count).

ETH:
- Added consortium mode 50G support.
- Added the ability to allow only selected speeds to be advertised during auto
  negotiation.
- Increased port capability from 16 to 32 bits to support more speeds.
  FW_PARAMS_PARAM_PFVF_PORT_CAPS32 added to query whether fw supports 16 or 32
  bit port capability.

OFLD:
- RDMA Write with immediate support added (iwarp 2.0 feature)
- FW_TLS_KEYCTX_TX_WR removed and security key management moved to driver.
- 256 offloaded connections support for iwarp on SO adapters.

https://www.illumos.org/issues/7431
  ZFS channel programs (ZCP) adds support for performing compound ZFS
  administrative actions via Lua scripts in a sandboxed environment (with time
  and memory limits).
  This initial commit includes both base support for running ZCP scripts, and a
  small initial library of API calls which support getting properties and
  listing, destroying, and promoting datasets.
  Testing: in addition to the included unit tests, channel programs have been in
  use at Delphix for several months for batch destroying filesystems. The
  dsl_destroy_snaps_nvl() call has also been replaced with

8552 ZFS LUA code uses floating point math

illumos/illumos-gate@916c8d8811
916c8d8811

https://www.illumos.org/issues/8552
  In the LUA interpreter used by "zfs program", the lua format() function
  accidentally includes support for '%f' and friends, which can cause compilation
  problems when building on platforms that don't support floating-point math in
  the kernel (e.g. sparc). Support for '%f' friends (%f %e %E %g %G) should be
  removed, since there's no way to supply a floating-point value anyway (all
  numbers in ZFS LUA are int64_t's).

- zfs-program.8 manual page is taken almost as is from the vendor repository,
  no FreeBSD-ification done
- fixed multiple instances of NULL being used where an integer is expected
- replaced ETIME and ECHRNG with ETIMEDOUT and EDOM respectively

This commit adds a modified version of Lua 5.2.4 under
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/lua, mirroring the
upstream.  See README.zfs in that directory for the description of Lua

fe182ba1d0 aesni(4): Add support for x86 SHA intrinsics
Some x86 class CPUs have accelerated intrinsics for SHA1 and SHA256.
Provide this functionality on CPUs that support it.

This implements CRYPTO_SHA1, CRYPTO_SHA1_HMAC, and CRYPTO_SHA2_256_HMAC.

Correctness: The cryptotest.py suite in tests/sys/opencrypto has been
enhanced to verify SHA1 and SHA256 HMAC using standard NIST test vectors.
The test passes on this driver.  Additionally, jhb's cryptocheck tool has
been used to compare various random inputs against OpenSSL.  This test also
passes.

Rough performance averages on AMD Ryzen 1950X (4kB buffer):
aesni:      SHA1: ~8300 Mb/s    SHA256: ~8000 Mb/s
cryptosoft:       ~1800 Mb/s    SHA256: ~1800 Mb/s

So ~4.4-4.6x speedup depending on algorithm choice.  This is consistent with
the results the Linux folks saw for 4kB buffers.

The driver borrows SHA update code from sys/crypto sha1 and sha256.  The
intrinsic step function comes from Intel under a 3-clause BSDL.[0]  The
intel_sha_extensions_sha<foo>_intrinsic.c files were renamed and lightly
modified (added const, resolved a warning or two; included the sha_sse
header to declare the functions).

bcf2b954c3 Add support for handling undefined instructions in userspace and the

This is initially used to work around a bug in old versions of QEMU that
trigger such an exception when reading from an ID register when it should
load z zero value.

I expect this could be used with other exception types, e.g. to emulate
special register access from userland.

newvers.sh looks for a .vcs subdirectory (e.g. .git, .svn) to determine
which vcs info tool to run (e.g., git rev-parse, svn info).

(As of r308789 if a .vcs subdirectory is not found at ${TOPDIR} then
newvers.sh walks up successive parent directories, testing for the .vcs
subdirectory at each step.  This is done in case the FreeBSD source is
built in a subdirectory as part of some larger project, but either way
newvers.sh still tests for the .vcs subdirectory.)

However, when using git worktree there is no .git subdirectory but
rather a plain text .git file which contains a reference to the main
working tree.

Change findvcs() to test that the .vcs entry exists, regardless of type.

bb2e8108e1 Add a new driver, ds13rtc, that handles all DS13xx series i2c RTC chips.
This driver supports only basic timekeeping functionality.  It completely
replaces the ds133x driver.  It can also replace the ds1374 driver, but that
will take a few other changes in MIPS code and config, and will be committed
separately.  It does NOT replace the existing ds1307 driver, which provides
access to some of the extended features on the 1307 chip, such as controlling
the square wave output signal.  If both ds1307 and ds13rtc drivers are
present, the ds1307 driver will outbid and win control of the device.

This driver can be configured with FDT data, or by using hints on non-FDT
systems.  In addition to the standard hints for i2c devices, it requires
a "chiptype" string of the form "dallas,ds13xx" where 'xx' is the chip id
(i.e., the same format as FDT compat strings).

There is a new platform_pl310 interface to replace the existing code. SoCs

Some of the CAM integration isn't complete (there are sleeps in the
device probe state machine, for example), but those minor issues can
be improved in-tree more easily than out of tree and shouldn't gate

53e0bebaca enable --build-id for the kernel link
A Build-ID is an identifier generated at link time to uniquely identify
ELF binaries.  It allows efficient confirmation that an executable or
shared library and a corresponding standalone debuginfo file match.
(Otherwise, a checksum of the debuginfo file must be calculated when
opening it in a debugger.)

The FreeBSD base system includes GNU bfd ld 2.17.50 as the linker for
architectures other than arm64.  Build-ID support was added to bfd ld
shortly after that version, so was not previously available to us.

We can now start making use of Build-ID as we migrate to using lld or
bfd ld from ports, conditionally enabled based on the LINKER_TYPE and
LINKER_VERSION make variables added in r320244 and subsequent commits.

f9cdbaba8d MFV r318946: 8021 ARC buf data scatter-ization
illumos/illumos-gate@770499e185
770499e185

https://www.illumos.org/issues/8021
  The ARC buf data project (known simply as "ABD" since its genesis in the ZoL
  community) changes the way the ARC allocates `b_pdata` memory from using linear
  `void *` buffers to using scatter/gather lists of fixed-size 1KB chunks. This
  improves ZFS's performance by helping to defragment the address space occupied
  by the ARC, in particular for cases where compressed ARC is enabled. It could
  also ease future work to allocate pages directly from `segkpm` for minimal-
  overhead memory allocations, bypassing the `kmem` subsystem.
  This is essentially the same change as the one which recently landed in ZFS on
  Linux, although they made some platform-specific changes while adapting this
  work to their codebase:
  1. Implemented the equivalent of the `segkpm` suggestion for future work
  mentioned above to bypass issues that they've had with the Linux kernel memory
  allocator.
  2. Changed the internal representation of the ABD's scatter/gather list so it
  could be used to pass I/O directly into Linux block device drivers. (This
  feature is not available in the illumos block device interface yet.)

FreeBSD notes:
- the actual (default) chunk size is 4KB (despite the text above saying 1KB)
- we can try to reimplement ABDs, so that they are not permanently
  mapped into the KVA unless explicitly requested, especially on
  platforms with scarce KVA
- we can try to use unmapped I/O and avoid intermediate allocation of a
  linear, virtual memory mapped buffer
- we can try to avoid extra data copying by referring to chunks / pages
  in the original ABD

40373cf5b8 Remove msdosfs -o large support.
Its purpose was to translate the values for msdosfs inode numbers,
which is calculated from the msdosfs structures describing the file,
into the range representable by 32bit ino_t.  The translation acted
for filesystems larger than 128Gb, it reserved the range 0xf0000000
(FILENO_FIRST_DYN) to UINT32_MAX and remembered some arbitrary
translation of ino >= FILENO_FIRST_DYN into this range.  It consumed
memory that could be only freed by unmount, and the translation was
not stable across remounts.

With ino_t type extended to 64 bit, there is no such issue and values
can be returned without compaction to 32bit.  That is, for the native
environments, the translation layer is not necessary and adds
significant undeserved code complexity.  For compat ABIs which use
32bit ino_t, the vfs.ino64_trunc_error sysctl provides some measures
to soften the failure mode when inode numbers truncation is not safe.

dc6a41b936 Add the infrastructure to support loading multiple versions of TCP
stack modules.

It adds support for mangling symbols exported by a module by prepending
a string to them. (This avoids overlapping symbols in the kernel linker.)

It allows the use of a macro as the module name in the DECLARE_MACRO()
and MACRO_VERSION() macros.

It allows the code to register stack aliases (e.g. both a generic name
["default"] and version-specific name ["default_10_3p1"]).

With these changes, it is trivial to compile TCP stack modules with
the name defined in the Makefile and to load multiple versions of the
same stack simultaneously. This functionality can be used to enable
side-by-side testing of an old and new version of the same TCP stack.
It also could support upgrading the TCP stack without a reboot.

9b8d05b8ac Add support for Amazon Elastic Network Adapter (ENA) NIC
ENA is a networking interface designed to make good use of modern CPU
features and system architectures.

The ENA device exposes a lightweight management interface with a
minimal set of memory mapped registers and extendable command set
through an Admin Queue.

The driver supports a range of ENA devices, is link-speed independent
(i.e., the same driver is used for 10GbE, 25GbE, 40GbE, etc.), and has
a negotiated and extendable feature set.

Some ENA devices support SR-IOV. This driver is used for both the
SR-IOV Physical Function (PF) and Virtual Function (VF) devices.

ENA devices enable high speed and low overhead network traffic
processing by providing multiple Tx/Rx queue pairs (the maximum number
is advertised by the device via the Admin Queue), a dedicated MSI-X
interrupt vector per Tx/Rx queue pair, and CPU cacheline optimized
data placement.

The ENA driver supports industry standard TCP/IP offload features such
as checksum offload and TCP transmit segmentation offload (TSO).
Receive-side scaling (RSS) is supported for multi-core scaling.

The ENA driver and its corresponding devices implement health
monitoring mechanisms such as watchdog, enabling the device and driver
to recover in a manner transparent to the application, as well as
debug logs.

Some of the ENA devices support a working mode called Low-latency
Queue (LLQ), which saves several more microseconds. This feature will
be implemented for driver in future releases.

5033c43b7a Add a driver for the Chelsio T6 crypto accelerator engine.
The ccr(4) driver supports use of the crypto accelerator engine on
Chelsio T6 NICs in "lookaside" mode via the opencrypto framework.

Currently, the driver supports AES-CBC, AES-CTR, AES-GCM, and AES-XTS
cipher algorithms as well as the SHA1-HMAC, SHA2-256-HMAC, SHA2-384-HMAC,
and SHA2-512-HMAC authentication algorithms.  The driver also supports
chaining one of AES-CBC, AES-CTR, or AES-XTS with an authentication
algorithm for encrypt-then-authenticate operations.

Note that this driver is still under active development and testing and
may not yet be ready for production use.  It does pass the tests in
tests/sys/opencrypto with the exception that the AES-GCM implementation
in the driver does not yet support requests with a zero byte payload.

To use this driver currently, the "uwire" configuration must be used
along with explicitly enabling support for lookaside crypto capabilities
in the cxgbe(4) driver.  These can be done by setting the following
tunables before loading the cxgbe(4) driver:

    hw.cxgbe.config_file=uwire

554e6778b6 hyperv/vmbus: Reorganize vmbus device tree
For GEN1 Hyper-V, vmbus is attached to pcib0, which contains the
resources for PCI passthrough and SR-IOV.  There is no
acpi_syscontainer0 on GEN1 Hyper-V.

For GEN2 Hyper-V, vmbus is attached to acpi_syscontainer0, which
contains the resources for PCI passthrough and SR-IOV.  There is
no pcib0 on GEN2 Hyper-V.

The ACPI VMBUS device now only holds its _CRS, which is empty as
of this commit; its existence is mainly for upward compatibility.

Device tree structure is suggested by jhb@.

a7dc31283a Remove the NATM framework including the en(4), fatm(4), hatm(4), and

Maintaining an address family and framework has real costs when we make
infrastructure improvements.  In the case of NATM we support no devices
manufactured in the last 20 years and some will not even work in modern
motherboards (some newer devices that patm(4) could be updated to
support apparently exist, but we do not currently have support).

With this change, support remains for some netgraph modules that don't
require NATM support code. It is unclear if all these should remain,
though ng_atmllc certainly stands alone.

Note well: FreeBSD 11 supports NATM and will continue to do so until at
least September 30, 2021.  Improvements to the code in FreeBSD 11 are
certainly welcome.

653e7d6396 Split iscsi(4) ctl frontend off of ctl(4) as cfiscsi(4)
The goal of this work is to remove the explicit dependency for ctl(4)
on iscsi(4), so end-users without iscsi(4) support in the kernel can
use ctl(4) for its other functions.

This allows those without iscsi(4) support built into the kernel to use
ctl(4) as a test mechanism. As a sidenote, this was possible around the
10.0-RELEASE period, but made impossible for end-users without iscsi(4)
between 10.0-RELEASE and 11.0-RELEASE.

Automatically load cfiscsi(4) from ctladm(8) and ctld(8) for backwards
compatibility with previously releases. The automatic loading feature is
compiled into the beforementioned tools if MK_ISCSI == yes when building
world.

Add a manpage for cfiscsi(4) and refer to it in ctl(4).

1811d6bf7f Add an experimental DTrace audit provider, which allows users of DTrace to
instrument security event auditing rather than relying on conventional BSM
trail files or audit pipes:

- Add a set of per-event 'commit' probes, which provide access to
  particular auditable events at the time of commit in system-call return.
  These probes gain access to audit data via the in-kernel audit_record
  data structure, providing convenient access to system-call arguments and
  return values in a single probe.

- Add a set of per-event 'bsm' probes, which provide access to particular
  auditable events at the time of BSM record generation in the audit
  worker thread. These probes have access to the in-kernel audit_record
  data structure and BSM representation as would be written to a trail
  file or audit pipe -- i.e., asynchronously in the audit worker thread.

DTrace probe arguments consist of the name of the audit event (to support
future mechanisms of instrumenting multiple events via a single probe --
e.g., using classes), a pointer to the in-kernel audit record, and an
optional pointer to the BSM data and its length. For human convenience,
upper-case audit event names (AUE_...) are converted to lower case in
DTrace.

DTrace scripts can now cause additional audit-based data to be collected
on system calls, and inspect internal and BSM representations of the data.
They do not affect data captured in the audit trail or audit pipes
configured in the system. auditd(8) must be configured and running in
order to provide a database of event information, as well as other audit
configuration parameters (e.g., to capture command-line arguments or
environmental variables) for the provider to operate.

864c28cf81 Use inline asm instead of unportable intrinsics for the SSE4 crc32
optimization.

This fixes building with gcc-4.2.1 (it doesn't support SSE4).
gas-2.17.50 [FreeBSD] supports SSE4 instructions, so this doesn't
need using .byte directives.

This fixes depending on host user headers in the kernel.

Fix user includes (don't depend on namespace pollution in <nmmintrin.h>
that is not included now).

The instrinsics had no advantages except to sometimes avoid compiler
pessimixations.  clang understands them a bit better than inline asm,
and generates better looking code which also runs better for cem, but
for me it just at the same speed or slower by doing excessive
unrollowing in all the wrong places.  gcc-4.2.1 also doesn't understand
what it is doing with unrolling, but with -O3 somehow it does more
unrolling that helps.

Reduce 1 of the the compiler pessimizations (copying a variable which
already satisfies an "rm" constraint in a good way by being in memory
and not used again, to different memory and accessing it there.  Force
copying it to a register instead).

Try to optimize the inner loops significantly, so as to run at full
speed on smaller inputs.  The algorithm is already very MD, and was
tuned for the throughput of 3 crc32 instructions per cycle found on
at least Sandybridge through Haswell.  Now it is even more tuned for
this, so depends more on the compiler not rearranging or unrolling
things too much.  The main inner loop for should have no difficulty
runing at full speed on these CPUs unless the compiler unrolls it too
much.  However, the main inner loop wasn't even used for buffers smaller
than 24K.  Now it is used for buffers larger than 384 bytes.  Now it
is not so long, and the main outer loop is used more.  The new
optimization is to try to arrange that the outer loop runs in parallel
with the next inner loop except for the final iteration; then reduce
the loop sizes significantly to take advantage of this.

72dec0792a - Add support for eMMC "partitions". Besides the user data area, i. e.
the default partition, eMMC v4.41 and later devices can additionally
  provide up to:
  1 enhanced user data area partition
  2 boot partitions
  1 RPMB (Replay Protected Memory Block) partition
  4 general purpose partitions (optionally with a enhanced or extended
    attribute)

  Of these "partitions", only the enhanced user data area one actually
  slices the user data area partition and, thus, gets handled with the
  help of geom_flashmap(4). The other types of partitions have address
  space independent from the default partition and need to be switched
  to via CMD6 (SWITCH), i. e. constitute a set of additional "disks".

  The second kind of these "partitions" doesn't fit that well into the
  design of mmc(4) and mmcsd(4). I've decided to let mmcsd(4) hook all
  of these "partitions" up as disk(9)'s (except for the RPMB partition
  as it didn't seem to make much sense to be able to put a file-system
  there and may require authentication; therefore, RPMB partitions are
  solely accessible via the newly added IOCTL interface currently; see
  also below). This approach for one resulted in cleaner code. Second,
  it retains the notion of mmcsd(4) children corresponding to a single
  physical device each. With the addition of some layering violations,
  it also would have been possible for mmc(4) to add separate mmcsd(4)
  instances with one disk each for all of these "partitions", however.
  Still, both mmc(4) and mmcsd(4) share some common code now e. g. for
  issuing CMD6, which has been factored out into mmc_subr.c.

  Besides simply subdividing eMMC devices, some Intel NUCs having UEFI
  code in the boot partitions etc., another use case for the partition
  support is the activation of pseudo-SLC mode, which manufacturers of
  eMMC chips typically associate with the enhanced user data area and/
  or the enhanced attribute of general purpose partitions.

  CAVEAT EMPTOR: Partitioning eMMC devices is a one-time operation.

- Now that properly issuing CMD6 is crucial (so data isn't written to
  the wrong partition for example), make a step into the direction of
  correctly handling the timeout for these commands in the MMC layer.
  Also, do a SEND_STATUS when CMD6 is invoked with an R1B response as
  recommended by relevant specifications. However, quite some work is
  left to be done in this regard; all other R1B-type commands done by
  the MMC layer also should be followed by a SEND_STATUS (CMD13), the
  erase timeout calculations/handling as documented in specifications
  are entirely ignored so far, the MMC layer doesn't provide timeouts
  applicable up to the bridge drivers and at least sdhci(4) currently
  is hardcoding 1 s as timeout for all command types unconditionally.
  Let alone already available return codes often not being checked in
  the MMC layer ...

- Add an IOCTL interface to mmcsd(4); this is sufficiently compatible
  with Linux so that the GNU mmc-utils can be ported to and used with
  FreeBSD (note that due to the remaining deficiencies outlined above
  SANITIZE operations issued by/with `mmc` currently most likely will
  fail). These latter will be added to ports as sysutils/mmc-utils in
  a bit. Among others, the `mmc` tool of the GNU mmc-utils allows for
  partitioning eMMC devices (tested working).

- For devices following the eMMC specification v4.41 or later, year 0
  is 2013 rather than 1997; so correct this for assembling the device
  ID string properly.

- Let mmcsd.ko depend on mmc.ko. Additionally, bump MMC_VERSION as at
  least for some of the above a matching pair is required.

- In the ACPI front-end of sdhci(4) describe the Intel eMMC and SDXC
  controllers as such in order to match the PCI one.
  Additionally, in the entry for the 80860F14 SDXC controller remove
  the eMMC-only SDHCI_QUIRK_INTEL_POWER_UP_RESET.

end up being executed on more than one worker thread simultaneously.
This might cause problems with code coming from Linux, which expects
serial behaviour, similar to Linux tasklets.

fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

d61db6be37 Use "build" instead of "all" when building ports modules
"all" in ports currently means "stage the ports", which requires root today,
and brings to light other potential issues, like ENAMETOOLONG with staged
directories (bug 161481, etc).

This fixes buildkernel for me when run as a non-root user, assuming all
of the prerequisites have been installed beforehand and are up-to-date.

1cdefd084d Optimise unmapped LinuxKPI page allocations.
When allocating unmapped pages, take advantage of the direct map on
AMD64 to get the virtual address corresponding to a page. Else all
pages allocated must be mapped because sometimes the virtual address
of a page is requested.

Move all page allocation and deallocation code into an own C-file.

Add support for GFP_DMA32, GFP_KERNEL, GFP_ATOMIC and __GFP_ZERO
allocation flags.

Make a clear separation between mapped and unmapped allocations.

0e8b3ab348 Exclude -flto when building *genassym.o
The build process generates *assym.h using nm from *genassym.o (which is
in turn created from *genassym.c).

When compiling with link-time optimization (LTO) using -flto, .o files
are LLVM bitcode, not ELF objects. This is not usable by genassym.sh,
so remove -flto from those ${CC} invocations.

ef23481a79 Add support for LinuxKPI tasklets.
Tasklets are implemented using a taskqueue and a small statemachine on
top. The additional statemachine is required to ensure all LinuxKPI
tasklets get serialized. FreeBSD taskqueues do not guarantee
serialisation of its tasks, except when there is only one worker
thread configured.

1e3db1de0c Make the LinuxKPI task struct persistent accross system calls.
A set of helper functions have been added to manage the life of the
LinuxKPI task struct. When an external system call or task is invoked,
a check is made to create the task struct by demand. A thread
destructor callback is registered to free the task struct when a
thread exits to avoid memory leaks.

This change lays the ground for emulating the Linux kernel more
closely which is a dependency by the code using the LinuxKPI APIs.

Add new dedicated td_lkpi_task field has been added to struct thread
instead of abusing td_retval[1].

Fix some header file inclusions to make LINT kernel build properly
after this change.

Bump the __FreeBSD_version to force a rebuild of all kernel modules.

cc5bbcb275 Add USB Mass Storage CTL frontend. This makes it possible
for USB OTG-capable hardware to implement device side of USB
Mass Storage, ie pretend it's a flash drive.  It's configured
in the same way as other CTL frontends, using ctladm(8)
or ctld(8).  Differently from usfs(4), all the configuration
can be done without rebuilding the kernel.

Testing and review is welcome.  Right now I'm still moving,
and I don't have access to my test environment, so I'm somewhat
reluctant to making larger changes to this code; on the other
hand I don't want to let it sit on Phab until my testing setup
is back, because I want to get it into 11.1-RELEASE.
