All I/O APIC pins are masked when an I/O APIC is first probed. The
APIC enumerator (MP Table or MADT) then parses its associated tables to
configure individual pins to set custom delivery modes or alternate
routing (e.g. routing IRQ 0 to intpin 2). Pins for regular interrupt
pins are left masked until the first interrupt is assigned. However,
pins with unusual settings (e.g. NMI or SMI) are never assigned an
interrupt and thus never re-programmed. The I/O APIC code used to
reprogram all interrupt pins during registration but this was lost in
r151979.
In theory, this is mostly a no-op as the ACPI APIC table does not
include a way to enumerate NMI or SMI pins for the I/O APIC, so only
systems using an MP Table would be affected.

r286227:
Decompose TCP INP_INFO lock to increase short-lived TCP connections scalability:
- The existing TCP INP_INFO lock continues to protect the global inpcb list
stability during full list traversal (e.g. tcp_pcblist()).
- A new INP_LIST lock protects inpcb list actual modifications (inp allocation
and free) and inpcb global counters.
It allows to use TCP INP_INFO_RLOCK lock in critical paths (e.g. tcp_input())
and INP_INFO_WLOCK only in occasional operations that walk all connections.

Some tools produce objects with a combined strtab and shstrtab.
These objects are not supported by crunchide since it rewrites the
symtab and strtab to "hide" symbols. This invalidates section header
offsets into a combined strtab/shstrtab.
In the future we could support these objects (by ensuring that we retain
unmodified section name strings in the output .strtab, and then rewriting
each section header's sh_name).

Specifically, use .Ta instead of tabs to separate column entries. While
here fix a few other things:
- Use .Sy for all column headers (previously only the first column header
was bold)
- Use .Dv to markup constants used for MIB names.
- Use "1234" and "4321" for the byte order descriptions without
thousands separators.
- Mark up header files in the first table with .In.

EFER_NXE is set in the EFER MSR by initializecpu() and must be set on all
CPUs in the system. When PG_NX support was added to PAE on i386, the
block to enable EFER_NXE was placed in a section of initializecpu() that
only runs if 'cpu == CPU_686'. During early boot, locore does an
initial pass to set cpu that sets it to CPU_686 on all CPUs later than
a Pentium. Later, printcpuinfo() adjusts the 'cpu' variable on
PII and later CPUs to one of CPU_PII, CPU_PIII, or CPU_P4. However,
printcpuinfo() is called after initializecpu() on the BSP, so the BSP
would enable EFER_NXE and pg_nx. The APs execute initializecpu() much
later after printcpuinfo() has run. The end result on a modern CPU was
that cpu was set to CPU_PIII when the APs invoked initializecpu(), so
they did not enable EFER_NXE. As a result, the APs would fault when
trying to access any pages marked with PG_NX set.
When booting a 2 CPU PAE kernel in bhyve this manifested as a hang before
single user mode. The attempt to execute /bin/init tried to copy out
the exec strings (argv, etc.) to a non-executable mapping while running
on the AP. The instruction kept faulting due to invalid bits in the PTE
in an infinite loop.
Fix this by moving the code to enable EFER_NXE out of the switch statement
on 'cpu' and always doing it if 'amd_feature' supports AMDID_NX.

307584 added the __min_size macro and replaced some static array sizes with
__min_size. However, stable/10 doesn't yet have any static array sizes, so
all this MFC does is add the __min_size macro.
Original commit message:
Fix C++ includability of crypto headers with static array sizes
C99 allows array function parameters to use the static keyword for their
sizes. This tells the compiler that the parameter will have at least the
specified size, and calling code will fail to compile if that guarantee is
not met. However, this syntax is not legal in C++.
This commit reverts r300824, which worked around the problem for
sys/sys/md5.h only, and introduces a new macro: min_size(). min_size(x) can
be used in headers as a static array size, but will still compile in C++
mode.

Currently, '/etc/rc.d/swaplate stop' removes all swap devices. This can be
very slow and may not even be possible if there is a lot of swap space in
use. However, removing swap devices is only needed for late swap devices
that may depend on daemons that subsequent shutdown steps stop. Normal swap
devices such as hard disk partitions will remain available throughout the
shutdown process and need not be removed.
In swapoff, interpret -aL to remove late swap devices only, and use this in
etc/rc.d/swaplate. The meaning of -aL in swapon remains unchanged (add all
swap devices, both normal and late).

r306740:
groff: use changelog date rather than file modification date in man pages
The source checkout date is not particularly relevant, and this makes
groff man pages build reproducibly.
r307150:
Avoid using 'head' in generating groff doc date
It may not be available in certain cross build cases.
Note that this is a slight change in functionality, in that now only the
first line of the source ChangeLog file is processed. This is acceptable
as groff will be retired and we won't encounter a possibly-different
ChangeLog format.

Fix ZIL records ordering when ZVOL opened both with and without FSYNC.
Before this an earlier writes to a ZVOL opened without FSYNC could get to
ZIL after later writes to the same ZVOL opened with FSYNC. Fix this by
replicating functionality of ZPL (zv_sync_cnt equivalent to z_sync_cnt),
marking all log records sync if anybody opened the ZVOL with FSYNC.

It allows to avoid extra GEOM providers flapping without significant need.
Since GEOM got resize support, we don't need to reopen provider to get new
size. If provider was orphaned and no longer valid, ZFS should already
know that, and in such case reopen should be done in full as expected.

In case of vdev detach, causing top level mirror vdev destruction, leaf
vdev changes its GUID to one of the destroyed mirror, that creates race
condition when GUID in vdev label may not match one in the pool config.
This change replicates logic nuance of vdev_validate() by adding special
exception, matching the vdev GUID against the top level vdev GUID.
Since this exception is not completely reliable (may give false positives
if we fail to erase label on detached vdev), use it only as last resort.
Quick way to reproduce this scenario now is detach vdev from a pool with
enabled autoextend. During vdev detach autoextend logic tries to reopen
remaining vdev, that always fails now since in-memory configuration is
already updated, while on-disk labels are not yet.

6988 spa_sync() spends half its time in dmu_objset_do_userquota_updates
Using a benchmark which creates 2 million files in one TXG, I observe
that the thread running spa_sync() is on CPU almost the entire time we
are syncing, and therefore can be a performance bottleneck. About 50% of
the time in spa_sync() is in dmu_objset_do_userquota_updates().
The problem is that dmu_objset_do_userquota_updates() calls
zap_increment_int(DMU_USERUSED_OBJECT) once for every file that was
modified (or created). In this benchmark, all the files are owned by the
same user/group, so all 2 million calls to zap_increment_int() are
modifying the same entry in the zap. The same issue exists for the
DMU_GROUPUSED_OBJECT.
We should keep an in-memory map from user to space delta while we are
syncing, and when we finish, iterate over the in-memory map and modify
the ZAP once per entry. This reduces the number of calls to
zap_increment_int() from "number of objects modified" to "number of
owners/groups of modified files".
This reduced the time spent in spa_sync() in the file create benchmark
by ~33%, from 11 seconds to 7 seconds.
