74eb18b6cc Define a single instance of ahci_devclass and reference it from all the
attachment code for various SOCs and busses.  Remove all the static and
should-have-been-static and named-differently instances of it.

This should eliminate the recently-grown build warnings about multiple
definitions when building arm kernels.

8fb0ef085c Enhance the interrupt capabilities of ti_pruss driver.
The existing ti_pruss driver for the PRUSS Hardware provided by the AM335x
ARM CPU has basic interrupt capabilities.  This updated driver provides some
more options:

 - Sysctl based configuration for the interrupts (for some examples, see the
   test plan in the phabricator review cited below).

 - A device file (/dev/pruss0.irqN) for each enabled interrupt. This file
   can be read and the device blocks if no irq has happened or returns an
   uint64_t timestamp based on nanouptime().

 - Each interrupt device file provides kqueue-based event notification,
   blocking read(), or select().

c5765d84ac Allow Raspberry Pi platform and drivers to be configured with upstream DTBs.
- Added more compatibility strings to drivers not yet converted
 - Added new RPI platform code compatibility string to match the ones used
   upstream
 - Adapted RPI and RPI2 DTS to match the new platform code compatibility
   string

The goal is to use the upstream DTBs as a replacement for our custom one.
This is now possible with these changes.

Additionally, as the RPI firmware automatically chooses the right DTB for
us, this would allow to have one common armv6 kernel for RPI0 and RPI1
(BCM2835-based), and one common armv7 kernel for RPI2 v1.1 (BCM2836-based),
and RPI2 v1.2 / RPI3 (BCM2837-based).

3f43239f21 The soisconnected() call removed from syncache_socket() in r307966 was
not extraneous in the TCP Fast Open (TFO) passive-open case.  In the
TFO passive-open case, syncache_socket() is being called during
processing of a TFO SYN bearing a valid cookie, and a call to
soisconnected() is required in order to allow the application to
immediately consume any data delivered in the SYN and to have a chance
to generate response data to accompany the SYN-ACK.  The removal of
this call to soisconnected() effectively converted all TFO passive
opens to having the same RTT cost as a standard 3WHS.

This commit adds a call to soisconnected() to syncache_tfo_expand() so
that it is only in the TFO passive-open path, thereby restoring TFO
passve-open RTT performance and preserving the non-TFO connection-rate
performance gains realized by r307966.

dfa1f80ce9 Fix an infinite loop in tcp_tw_2msl_scan() when an INP_TIMEWAIT inp has
been destroyed before its tcptw with INVARIANTS undefined.

This is a symmetric change of r307551:

A INP_TIMEWAIT inp should not be destroyed before its tcptw, and INVARIANTS
will catch this case.  If INVARIANTS is undefined it will emit a log(LOG_ERR)
and avoid a hard to debug infinite loop in tcp_tw_2msl_scan().

0bd904ed47 Work around bcm283x silicon bugs to make i2c repeat-start work for the most
common case where it's needed -- a write followed by a read to the same slave.

The i2c controller in this chip only performs complete transfers, it does
not provide control over start/repeat-start/stop operations on the bus.
Thus, we have gotten a full stop/start sequence rather than a repeat-start
when doing a typical i2c slave access of "write address, read data".  Some
i2c slave devices require a repeat-start to work correctly.

These changes cause the controller to do a repeat-start by pre-staging the
read parameters in the controller registers immediate after the controller
has latched the values for the initial write operation, but before any
bytes are actually written.  With the values pre-staged, when the write
portion of the transfer completes, the state machine in the silicon sees
a new start operation already staged and that causes it to perform a
repeat-start.  The key to tricking the buggy hardware into doing this is
to avoid prefilling any output data in the transmit FIFO so that it is
possible to catch the silicon in the state where transmit values are
latched but the transmit isn't completed yet.

  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).

Use make_dev_s(9) to create device, since the device ioctl interface
needs to access si_drv1 to get softc pointer.

Remove the common but not functional attempt to prevent parallel
accesses by file descriptors by blocking more than one open.  Either
threads in one process, or forked siblings, or file descriptors passed
over unix domain sockets all allow to execute parallel requests once
one fd is opened.  Since ioctl handler uses smbus_request_bus() to
take the bus ownership, the correct mechanism establishes exclusive
access already.

0ffc7ed7e3 Have uiomove_object_page() keep accessed pages in the active queue.
Previously, uiomove_object_page() would maintain LRU by requeuing the
accessed page. This involves acquiring one of the heavily contended page
queue locks. Moreover, it is unnecessarily expensive for pages in the
active queue.

As of r254304 the page daemon continually performs a slow scan of the
active queue, with the effect that unreferenced pages are gradually
moved to the inactive queue, from which they can be reclaimed. Prior to
that revision, the active queue was scanned only during shortages of
free and inactive pages, meaning that unreferenced pages could get
"stuck" in the queue. Thus, tmpfs was required to use the inactive queue
and requeue pages in order to maintain LRU. Now that this is no longer
the case, tmpfs I/O operations can use the active queue and avoid the
page queue locks in most cases, instead setting PGA_REFERENCED on
referenced pages to provide pseudo-LRU.

4b06638f20 Update cpucontrol(8).
Mention new -n flag.
Remove optional -h from the operation list lines, -h would cause the
utility to exit without performing the action.
Explain the default path behavior, list default path.
Correct example of update performed from the non-default path,
it needs -n and the trailing slash is redundand.
Remove useless BUGS section.

0539c17353 Allow to disable default microcode updates search path with the new
'-n' option.

Look for updates in the default locations only after user-supplied
locations are tried.

If newer microcode files are put into non-standard path, both measures
allow to avoid situation where older update loaded from the default
path first, and then the second update is applied from non-standard
path.  Applying intermediate updates might be undesirable.

efea6b20b9 Add support for Flex File Layout to the pNFS client structures.
This patch modifies the pNFS client layout and deviceinfo structures
to add fields and unions for the Flex File Layout. Until a future
commit adds Flex File layout support, these new fields are not used.
This patch should not affect the "pnfs" option for File Layout.

e8b437ef9a Remove spurious $flags; it's a paste-o from copying the line from rc.subr.
Also, add a comment documenting the args passed to mount_md().

50e3590c44 Enhance mdmfs(8) to work with tmpfs(5).
Existing scripts and associated config such as rc.initdiskless, rc.d/var,
and others, use mdmfs to create memory filesystems. That program accepts a
size argument which allows SI suffixes and treats an unsuffixed number as a
count of 512 byte sectors. That makes it difficult to convert existing
scripts to use tmpfs instead of mdmfs, because tmpfs treats unsuffixed
numbers as a count of bytes. The script logic to deal with existing user
config that might include suffixed and unsuffixed numbers is... unpleasant.

Also, there is no g'tee that tmpfs will be available. It is sometimes
configured out of small-resource embedded systems to save memory and flash
storage space.

These changes enhance mdmfs(8) so that it accepts two new values for the
'md-device' arg: 'tmpfs' and 'auto'. With tmpfs, the program always uses
tmpfs(5) (and fails if it's not available). With 'auto' the program prefers
tmpfs, but falls back to using md(4) if tmpfs isn't available. It also
handles the -s <size> argument so that the mdconfig interpetation of
unsuffixed numbers applies when tmpfs is used as well, so that existing user
config keeps working after a switch to tmpfs.

A new rc setting, mfs_type, is added to etc/defaults/rc.conf to let users
force the use of tmpfs or md; the default value is "auto".

50cf4f8950 aesni(4): Fix GCC build
The GCC xmmintrin.h header brokenly includes mm_malloc.h unconditionally.
(The Clang version of xmmintrin.h only includes mm_malloc.h if not compiling
in standalone mode.)

Hack around GCC's broken header by defining the include guard macro ahead of
including xmmintrin.h.

51bcc337dd netsmb: Fix buggy/racy smb_strdupin()
smb_strdupin() tried to roll a copyin() based strlen to allocate a buffer
and then blindly copyin that size.  Of course, a malicious user program
could simultaneously manipulate the buffer, resulting in a non-terminated
string being copied.

Later assumptions in the code rely upon the string being nul-terminated.

Just use copyinstr() and drop the racy sizing.
