6443773dab make critical_{enter, exit} inline
Avoid pulling in all of the <sys/proc.h> dependencies by
automatically generating a stripped down thread_lite exporting
only the fields of interest. The field declarations are type checked
against the original and the offsets of the generated result is
automatically checked.

kib has expressed disagreement and would have preferred to simply
use genassym style offsets (which loses type check enforcement).
jhb has expressed dislike of it due to header pollution and a
duplicate structure. He would have preferred to just have defined
thread in _thread.h. Nonetheless, he admits that this is the only
viable solution at the moment.

The impetus for this came from mjg's D15331:
"Inline critical_enter/exit for amd64"

030efb3cc6 newvers.sh: avoid possibly invalid relative directory
Previously newvers.sh passed --work-tree=${VCSDIR}/.. when invoking git.
When using git worktree .git is actually a file, not a directory, and
.git/.. is not a valid path.  Although it appears git handles this
internally (perhaps it normalizes the path first), it is simple enough
for the script to store both the working tree top-level directory and
the VCS (.git) directory, so do so.

9e28e9855f [rpi] Add SDHOST device driver for Raspberry Pi
SDHOST is another SD controller that is present on Raspberry Pi (the
other one is SDHC and handled by bcm2835_sdhci driver). Both
controllers are capable of providing interface to SD card, actual
configuration can be set in dtb file. At the moment custom DTBs for
RPi/RPi2 have sdhost node disabled. On RPi3 sdhost is disabled in
snapshot images by applying mmc.dtbo overlay. To enalbe both devices
user has to edit config.txt on FAT partition and remove or comment
"dtoverlay=mmc" line.

When no overlay applied on RPi3 SDHOST controls SD card and SDHC
interface can be used for SDIO. mmc.dtbo overlay disables SDHOST node
and switches SD card over to SDHC.  Likewise sdhost.dtbo overlay (not
currently included in snapshot image, but can be obtained from firmare
repo[1]) disabled SDHC node and switch SD card over to SDHOST.

1fcf4de055 Incorporate bus and chip select numbers into spigen(4) cdev names. Rather
than assigning spigen device names in order of creation, this uses a device
name that corresponds to the owning spibus and chip-select index.

Example: /dev/spigen0.1 would be a child of spibus0, and use cs = 1

The intent is for systems like Raspberry Pi to have a consistent way of
using an SPI interface with a specific cs value from a user application.
Otherwise, there is no consistent way of knowing which cs pin will be
assigned to a particular spigen device. The alternative is to specify
everything in "the right order" in an overlay file, which is less than
ideal. Additionally, this duplicates (to some extent) the way Linux handles
a similar situation with their 'spidev' device, so it would be somewhat
familiar to those who also use Linux.

A new kernel config option, SPIGEN_LEGACY_CDEVNAME, causes the driver to
also create /dev/spigenN device name aliases, with N incrementing in the
order of device instantiation.  This is provided to ease the transition
for existing systems using the original naming convention (particularly
when these changes are MFC'd to stable branches).

5e03278fee Add MMCCAM support to AllWinner MMC driver
Using MMCCAM on AllWinner boards is now possible, reaching highest
possible data transfer speed.

For now, MMCCAM doesn't scan cards on boot. This means that scanning
has to be done manually and that it's not possible to mount root FS
from MMC/SD card since there is no block device at the boot time.

For manually scanning the cards, run:
# camcontrol rescan X:0:0
Where X is the bus number (look at camcontrol devlist to determine
bus number assigned to the MMC controller).

fb47a3769c MAC/veriexec implements a verified execution environment using the MAC
framework.

The code is organized into a few distinct pieces:

* The meta-data store (in veriexec_metadata.c) which maps a file system
  identifier, file identifier, and generation key tuple to veriexec
  meta-data record.

* Fingerprint management (in veriexec_fingerprint.c) which deals with
  calculating the cryptographic hash for a file and verifying it. It also
  manages the loadable fingerprint modules.

* MAC policy implementation (in mac_veriexec.c) which implements the
  following MAC methods:

mpo_init
  Initializes the veriexec state, meta-data store, fingerprint modules,
  and registers mount and unmount EVENTHANDLERs

mpo_syscall
  Implements the following per-policy system calls:
  MAC_VERIEXEC_CHECK_FD_SYSCALL
    Check a file descriptor to see if the referenced file has a valid
    fingerprint.
  MAC_VERIEXEC_CHECK_PATH_SYSCALL
    Check a path to see if the referenced file has a valid fingerprint.

mpo_kld_check_load
  Check if loading a kld is allowed. This checks if the referenced vnode
  has a valid fingerprint.

mpo_mount_destroy_label
  Clears the veriexec slot data in a mount point label.

mpo_mount_init_label
  Initializes the veriexec slot data in a mount point label.
  The file system identifier is saved in the veriexec slot data.

mpo_priv_check
  Check if a process is allowed to write to /dev/kmem and /dev/mem
  devices.
  If a process is flagged as trusted, it is allowed to write.

mpo_proc_check_debug
  Check if a process is allowed to be debugged. If a process is not
  flagged with VERIEXEC_NOTRACE, then debugging is allowed.

mpo_vnode_check_exec
  Check is an exectuable is allowed to run. If veriexec is not enforcing
  or the executable has a valid fingerprint, then it is allowed to run.
  NOTE: veriexec will complain about mismatched fingerprints if it is
  active, regardless of the state of the enforcement.

mpo_vnode_check_open
  Check is a file is allowed to be opened. If verification was not
  requested, veriexec is not enforcing, or the file has a valid
  fingerprint, then veriexec will allow the file to be opened.

mpo_vnode_copy_label
  Copies the veriexec slot data from one label to another.

mpo_vnode_destroy_label
  Clears the veriexec slot data in a vnode label.

mpo_vnode_init_label
  Initializes the veriexec slot data in a vnode label.
  The fingerprint status for the file is stored in the veriexec slot data.

* Some sysctls, under security.mac.veriexec, for setting debug level,
  fetching the current state in a human-readable form, and dumping the
  fingerprint database are implemented.

* The MAC policy implementation source file also contains some utility
  functions.

* A set of fingerprint modules for the following cryptographic hash
  algorithms:
  RIPEMD-160, SHA1, SHA2-256, SHA2-384, SHA2-512

* Loadable module builds for MAC/veriexec and fingerprint modules.

 WARNING: Using veriexec with NFS (or other network-based) file systems is
          not recommended as one cannot guarantee the integrity of the files
          served, nor the uniqueness of file system identifiers which are
          used as key in the meta-data store.

ebf95d96d9 Split the PowerISA 3.0 HPT implementation from historic
PowerISA 3.0 makes several changes to not only the format of the HPT but
also the behavior surrounding it.  For instance, TLBIE no longer requires
serialization.  Removing this lock cuts buildworld time in half on a
18-core/72-thread POWER9 system, demonstrating that this lock is highly
contended on such a system.

There was odd behavior observed trying to make this change in a
backwards-compatible manner in moea64_native.c, so the best option was to
fully split it, and largely revert the original changes adding POWER9
support to the original file.

7b2c7b92be md: use prestaged mfs_root
On PowerNV systems, the rootfs is passed through kexec, which loads the rootfs
into memory and set two fdt entries to describe where the file is located in
the memory;

I need to pass this memory region to the md device as a mfs_root, but, current
md driver does not support two things:

 * Just getting a pointer from an external (bootloader) memory. If I need to
workaround it, I would need to declare a static array and memcopy from this
external memory to this static variable.

 * The size of the image. The usage of mfs_root_end, which is not a pointer,
seems to be not possible for this prestaged scenario.

This patch simply adds a new way to load mfs_root from memory.

gzipped aout.  It is currently broken even for i386 (a call to vm fails).
amd64 has always attempted to configure and test it, but it depends on
COMPAT_AOUT (as noted).  The bug that it depends on unconfigured files

e92a1350b5 hwpmc: remove unused pre-table driven bits for intel
Intel now provides comprehensive tables for all performance counters
and the various valid configuration permutations as text .json files.
Libpmc has been converted to use these and hwpmc_core has been greatly
simplified by moving to passthrough of the table values.

The one gotcha is that said tables don't support pentium pro and and pentium
IV. There's very few users of hwpmc on _amd64_ kernels on new hardware. It is
unlikely that anyone is doing low level optimization on 15 year old Intel
hardware. Nonetheless, if someone feels strongly enough to populate the
corresponding tables for p4 and ppro I will reinstate the files in to the
build.

3df266dff9 arm64: rockchip: Add proper armclock support
The core clock (armclk) on RockChip SoC is special.
It can derive it's clock from many PLLs but RockChip recommand to do it
from "apll" on old SoC and "npll" on new SoC. The reason for choosing npll
is that it's have less jitter and is more close to the arm core on the SoC.
r333314 added the core clock as a composite clock but due to it's specials
property we need to deal with it differently.
A new rk_clk_armclk type is added for this and it supports only the "npll"
as we don't run on old RockChip SoC that only have the "apll".
It will always reparent to "npll" and set the frequency according to a rate
table that is known to be good.
For now we set the "npll" to the desired frequency and just set the core clk
divider to 1 as its parent it just used for the core clk.

Summary:
PowerNV architectures (in the test case POWER9) export sensors via the device
tree, which are accessed via OPAL calls.  This adds sysctl nodes for each
device in a generic fashion.  New sysctl nodes are:

dev.opal_sensor.N.sensor
dev.opal_sensor.N.sensor_min
dev.opal_sensor.N.sensor_max
dev.opal_sensor.N.type
dev.opal_sensor.N.label

These are rooted at a parent attachment under opal, called opalsens.  This does
not add support for the "sensor groups" defined in the device tree.

3076898a56 allwinner: Add h3 spi driver
This driver is compatible with H3/H5/A64.
Test was done on the OrangePi-PC2 board (H5 based), which have a mx25l1606e
spi flash on it, by writing u-boot image, reading it and booting from the spi.
There is still room for improvement especially on reading using the controller
automatic burst which will avoid us to write dummy data to the TX FIFO.
DMA is also not supported as we currently don't support the DMA controller on
those SoCs
Only add a kernel module for it.

09f6ff4f1a iflib(9): Add support for cloning pseudo interfaces
Part 3 of many ...
The VPC framework relies heavily on cloning pseudo interfaces
(vmnics, vpc switch, vcpswitch port, hostif, vxlan if, etc).

This pulls in that piece. Some ancillary changes get pulled

ff8f1e8332 Error out on attempt to link amd64 kernel with old binutils linker
As of r333461 we require ifunc support to link a working amd64 kernel.
The default in-tree bootstrap linker is lld and it has the required
support, as does any modern out-of-tree binutils linker.  The in-tree
GNU ld is from binutils 2.17.50 and it does not have ifunc support,
so produce an error rather than a broken kernel.

6a909b9680 amd64: replace libkern's memset and memmove with assembly variants
memmove is repurposed bcopy (arguments swapped, return value added)
The libkern variant is a wrapper around bcopy, so this is a big
improvement.

memset is repurposed memcpy. The librkern variant is doing fishy stuff,
including branching on 0 and calling bzero.

Both functions are rather crude and subject to partial depessimization.

This is a soft prerequisite to adding variants utilizing the
'Enhanced REP MOVSB/STOSB' bit and let the kernel patch at runtime.

This is a component of a system which lets the kernel dump core to

The server component is available in the ports tree. netdump is
particularly useful on diskless systems.

The netdump(4) man page contains some details describing the protocol.
Support for configuring netdump will be added to dumpon(8) in a future
commit. To use netdump, the kernel must have been compiled with the
NETDUMP option.

The initial revision of netdump was written by Darrell Anderson and
was integrated into Sandvine's OS, from which this version was derived.

d86c1f0dc1 i386 4/4G split.
The change makes the user and kernel address spaces on i386
independent, giving each almost the full 4G of usable virtual addresses
except for one PDE at top used for trampoline and per-CPU trampoline
stacks, and system structures that must be always mapped, namely IDT,
GDT, common TSS and LDT, and process-private TSS and LDT if allocated.

By using 1:1 mapping for the kernel text and data, it appeared
possible to eliminate assembler part of the locore.S which bootstraps
initial page table and KPTmap.  The code is rewritten in C and moved
into the pmap_cold(). The comment in vmparam.h explains the KVA
layout.

There is no PCID mechanism available in protected mode, so each
kernel/user switch forth and back completely flushes the TLB, except
for the trampoline PTD region. The TLB invalidations for userspace
becomes trivial, because IPI handlers switch page tables. On the other
hand, context switches no longer need to reload %cr3.

copyout(9) was rewritten to use vm_fault_quick_hold().  An issue for
new copyout(9) is compatibility with wiring user buffers around sysctl
handlers. This explains two kind of locks for copyout ptes and
accounting of the vslock() calls.  The vm_fault_quick_hold() AKA slow
path, is only tried after the 'fast path' failed, which temporary
changes mapping to the userspace and copies the data to/from small
per-cpu buffer in the trampoline.  If a page fault occurs during the
copy, it is short-circuit by exception.s to not even reach C code.

The change was motivated by the need to implement the Meltdown
mitigation, but instead of KPTI the full split is done.  The i386
architecture already shows the sizing problems, in particular, it is
impossible to link clang and lld with debugging.  I expect that the
issues due to the virtual address space limits would only exaggerate
and the split gives more liveness to the platform.

711c77093c Fix using wrong SYSDIR after r331683.
This was inadvertently overriding the first found SYSDIR with the last
of /usr/src which could result in the wrong headers being used if not
building from /usr/src.

SYSDIR?= is not used here to avoid evaluating the exists() when unneeded.

3d5b3b0a44 Tune xDMA interface slightly:
o Move descriptors allocation to DMA engine driver
o Add generic xdma_request() routine
o Add less-generic scatter-gather application based on xdma interface

Typical operation flow in peripheral device driver is:

1. Get xDMA controller
sc->xdma_tx = xdma_ofw_get(sc->dev, "tx");

2. Allocate virtual channel
sc->xchan_tx = xdma_channel_alloc(sc->xdma_tx, caps);

3. Setup transfer status callback
xdma_setup_intr(sc->xchan_tx, my_tx_intr, sc, &sc->ih_tx);

4. Request a transfer(s)
ret = xdma_request(sc->xchan_tx, &req);

5. Free the channel
xdma_channel_free(sc->xdma_tx);

6. Free the controller
xdma_put(sc->xdma_tx);

2ff91c175e netmap: align codebase to the current upstream (commit id 3fb001303718146)
Changelist:
    - Turn tx_rings and rx_rings arrays into arrays of pointers to kring
      structs. This patch includes fixes for ixv, ixl, ix, re, cxgbe, iflib,
      vtnet and ptnet drivers to cope with the change.
    - Generalize the nm_config() callback to accept a struct containing many
      parameters.
    - Introduce NKR_FAKERING to support buffers sharing (used for netmap
      pipes)
    - Improved API for external VALE modules.
    - Various bug fixes and improvements to the netmap memory allocator,
      including support for externally (userspace) allocated memory.
    - Refactoring of netmap pipes: now linked rings share the same netmap
      buffers, with a separate set of kring pointers (rhead, rcur, rtail).
      Buffer swapping does not need to happen anymore.
    - Large refactoring of the control API towards an extensible solution;
      the goal is to allow the addition of more commands and extension of
      existing ones (with new options) without the need of hacks or the
      risk of running out of configuration space.
      A new NIOCCTRL ioctl has been added to handle all the requests of the
      new control API, which cover all the functionalities so far supported.
      The netmap API bumps from 11 to 12 with this patch. Full backward
      compatibility is provided for the old control command (NIOCREGIF), by
      means of a new netmap_legacy module. Many parts of the old netmap.h
      header has now been moved to netmap_legacy.h (included by netmap.h).

6469bdcdb6 Move most of the contents of opt_compat.h to opt_global.h.
opt_compat.h is mentioned in nearly 180 files. In-progress network
driver compabibility improvements may add over 100 more so this is
closer to "just about everywhere" than "only some files" per the
guidance in sys/conf/options.

Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset of
sys/compat/linux/*.c.  A fake _COMPAT_LINUX option ensure opt_compat.h
is created on all architectures.

Move COMPAT_LINUXKPI to opt_dontuse.h as it is only used to control the
set of compiled files.

b09de0b34a Add support for the Coresight technology from ARM Ltd.
ARM Coresight is a solution for debug and trace of complex SoC designs.

This includes a collection of drivers for ARM Coresight interconnect
devices within a small Coresight framework.

Supported devices are:
o Embedded Trace Macrocell v4 (ETMv4)
o Funnel
o Dynamic Replicator
o Trace Memory Controller (TMC)
o CPU debug module

Devices are connected to each other internally in SoC and the
configuration of each device endpoints is described in FDT.

Typical trace flow (as found on Qualcomm Snapdragon 410e):
CPU0 -> ETM0 -> funnel1 -> funnel0 -> ETF -> replicator -> ETR -> DRAM
CPU1 -> ETM1 -^
CPU2 -> ETM2 -^
CPU3 -> ETM3 -^

Note that both Embedded Trace FIFO (ETF) and Embedded Trace Router (ETR)
are hardware configurations of TMC.

This is required for upcoming HWPMC tracing support.

This is tested on single-core system only.

28da5c6d7a Remove MK_AUTO_OBJ from env passed to PORTS_MODULES
This fixes a failure to resolve object file paths seen when buildkernel
(which sets MK_AUTO_OBJ=yes) and installkernel (which sets MK_AUTO_OBJ=no)
are run as separate steps.  r329232 partially fixed this scenario by removing
MAKEOBJDIR, but it seems the AUTO_OBJ setting also needs to be on the same
page for the build and install steps.

ef270ab1b6 Bring in the Broadcom/Emulex Fibre Channel driver, ocs_fc(4).
The ocs_fc(4) driver supports the following hardware:

Emulex 16/8G FC GEN 5 HBAS
	LPe15004 FC Host Bus Adapters
	LPe160XX FC Host Bus Adapters

Emulex 32/16G FC GEN 6 HBAS
	LPe3100X FC Host Bus Adapters
	LPe3200X FC Host Bus Adapters

The driver supports target and initiator mode, and also supports FC-Tape.

Note that the driver only currently works on little endian platforms.  It
is only included in the module build for amd64 and i386, and in GENERIC
on amd64 only.
