7b445033ff On exec, single-threading must be enforced before arguments space is
allocated from exec_map.  If many threads try to perform execve(2) in
parallel, the exec map is exhausted and some threads sleep
uninterruptible waiting for the map space.  Then, the thread which won
the race for the space allocation, cannot single-thread the process,
causing deadlock.

bfca9c9400 Turn ieee80211_start_scan_locked() into a swscan module private method.
It turns out that ieee80211_start_scan_locked() is only ever called by
the swscan code and it won't likely be required by firmware scanning
implementations.

So, don't bother keeping it in ieee80211_scan.c and it likely won't
become an API call.

Tested:

* Intel 5100, STA mode
* AR5416, STA mode

3265af355a Attempt to address Bug #176201 - don't advertise what the AP announced
to us. Instead, advertise what we can do based on what the AP says and what
we're capped at by the VAP settings.

For non-STA modes we still advertise what our VAP settings are.

It may be that I've over-complicated this and instead of capping things
we can just always announce what we're capable of.  But this should at least
stop the blatantly wrong handling of A-MPDU parameters.

(I'll happily simplify things if someone can dig up a replacement, better
compliant behaviour.)

88feae84be Merge ^/projects/release-arm-redux into ^/head.
Of note:

- This commit adds native FreeBSD/arm release build support without
  requiring out-of-tree utilities.

- Part of this merge removes the WANDBOARD-{SOLO,DUAL,QUAD} kernel
  configuration files, for which the IMX6 kernel configuration file
  should be used instead.

- The resulting images have a 'freebsd' user (password 'freebsd'),
  to allow ssh(1) access when console access is not available (VGA
  or serial).  The default 'root' user password is set to 'root'.

- The /etc/ttys file for arm images now enable both ttyv0 and ttyu0
  by default.

44ec2b63c5 The vmem callback to reclaim kmem arena address space on low or
fragmented conditions currently just wakes up the pagedaemon.  The
kmem arena is significantly smaller then the total available physical
memory, which means that there are loads where kmem arena space could
be exhausted, while there is a lot of pages available still.  The
woken up pagedaemon sees vm_pages_needed != 0, verifies the condition
vm_paging_needed() which is false, clears the pass and returns back to
sleep, not calling neither uma_reclaim() nor lowmem handler.

To handle low kmem arena conditions, create additional pagedaemon
thread which calls uma_reclaim() directly.  The thread sleeps on the
dedicated channel and kmem_reclaim() wakes the thread in addition to
the pagedaemon.

a546448b8d Rewrite amd64 PCID implementation to follow an algorithm described in
the Vahalia' "Unix Internals" section 15.12 "Other TLB Consistency
Algorithms".  The same algorithm is already utilized by the MIPS pmap
to handle ASIDs.

The PCID for the address space is now allocated per-cpu during context
switch to the thread using pmap, when no PCID on the cpu was ever
allocated, or the current PCID is invalidated.  If the PCID is reused,
bit 63 of %cr3 can be set to avoid TLB flush.

Each cpu has PCID' algorithm generation count, which is saved in the
pmap pcpu block when pcpu PCID is allocated.  On invalidation, the
pmap generation count is zeroed, which signals the context switch code
that already allocated PCID is no longer valid.  The implication is
the TLB shootdown for the given cpu/address space, due to the
allocation of new PCID.

The pm_save mask is no longer has to be tracked, which (significantly)
reduces the targets of the TLB shootdown IPIs.  Previously, pm_save
was reset only on pmap_invalidate_all(), which made it accumulate the
cpuids of all processors on which the thread was scheduled between
full TLB shootdowns.

Besides reducing the amount of TLB shootdowns and removing atomics to
update pm_saves in the context switch code, the algorithm is much
simpler than the maintanence of pm_save and selection of the right
address space in the shootdown IPI handler.

b57a73f8e7 If x86 CPU implementation of the MWAIT instruction reasonably
interacts with interrupts, query ACPI and use MWAIT for entrance into
Cx sleep states.  Support C1 "I/O then halt" mode.  See Intel'
document 302223-007 "Intelб╝ Processor Vendor-Specific ACPI Interface
Specification" for description.

Move the acpi_cpu_c1() function into x86/cpu_machdep.c and use
it instead of inlining "sti; hlt" sequence in several places.

In the acpi(4) man page, besides documenting the dev.cpu.N.cx_methods
sysctl, correct the names for dev.cpu.N.{cx_usage,cx_lowest,cx_supported}
sysctls.

Both jkim and avg have some other patches implementing the mwait
functionality; this work is unrelated.  Linux does not rely on the
ACPI to provide correct tables describing Cx modes.  Instead, the
driver has pre-defined knowledge of the CPU models, it was supplied by
Intel.

e735691b61 Place VM objects on the object list when created and never remove them.
This is ok since objects come from a NOFREE zone and allows objects to
be locked while traversing the object list without triggering a LOR.

Ensure that objects on the list are marked DEAD while free or stillborn,
and that they have a refcount of zero.  This required updating most of
the pagers to explicitly mark an object as dead when deallocating it.
(Only the vnode pager did this previously.)

1ca4eb3acc Port x86 busdma to ARM64
The x86 busdma subsystem allows using multiple implementations.
By default the classic bounce buffer approach is used, however
on systems with IOMMU it could be in runtime switched to more
efficient hardware accelerated implementation.

This commit adds ARM64 port of the x86 busdma framework and bounce
buffer backend. It is ready to use on IO coherent systems. If the
IO coherency cannot be guaranteed, the cache management operations have
to be added to this code in places marked by /* XXX ARM64TODO (...) */
comments. Also IOMMU support might be added by registering another
busdma implementation like it is already done on the x86.
