017d485987 synaptics: more support for semi-MT trackpads.
Several improvements to the Synaptics driver to support
semi-multitouch trackpads and some other fixes:

- Two finger scrolling support for "semi-MT" touchpads. Those include
many of the older Synaptics touchpads before "true" multitouch support
(indicated by capMultiFinger). Semi-MT touchpads can report a second
finger position, but the X or Y coordinate may be swapped with some
coordinate of the first finger. This is a result of how the hardware
works internally. Therefore, all that can be reliably extracted is the
bounding box of the two finger positions. Semi-MT touchpads can be
recognized by the capAdvancedGestures capability bit. After setting the
mode byte, advanced gestures mode has to be enabled. Then, data packets
compatible with the capMultiFinger format are sent, so the same two
finger scrolling code can be leveraged. Enabling advanced gestures mode
on true multitouch touchpads should be harmless. Linux seems to always
enable advanced gestures mode.

- Put mode setting logic into own functions synaptics_preferred_mode()
and synaptics_set_mode() to have this in one place.
synaptics_passthrough_on() and synaptics_passthrough_off() currently
always use 0xc1 as the mode byte, which may be wrong for touchpads that
don't have capExtended.

- Expose X and Y resolution of touchpad to userland. Also expose minimum
and maximum X and Y coordinates. This is useful for programs in
userspace that read raw PSM packets (with PSM_LEVEL_NATIVE enabled) and
need to interpret the coordinates.

- Also send "extended w mode" packets (see section 3.2.9 of
511-000275-01_RevB.pdf) to userspace if PSM_LEVEL_NATIVE is enabled.
This is useful for userspace programs/drivers such as
xf86-input-synaptics that can handle these packets.

- Fix parsing of nExtendedQueries, and request extended/continued
capability bits depending on this value.

- capReportsMax, capClearPad, capAdvancedGestures and capCoveredPad must
be extracted from status[0] and not status[2], I think.

31825f28cf Create a relocatable instance of ubldr for ARM. The original ubldr,
static-linked to run at a fixed position, is still installed to maintain
compatibility with existing configurations.  The makefile now also creates
and installs ubldr.bin, a stripped binary (no elf headers) with an entry
point offset of 0 that can be loaded by u-boot at any address and launched
with "go ${loadaddr}".

To use ubldr.bin, U-Boot must still be built with the CONFIG_API option,
but no longer needs the CONFIG_ELF option.

53d1c63711 recv(),send(): Directly call interposing entry instead of going through PLT.
recv() and send()'s calls to recvfrom() and sendto() are much like
waitpid()'s call to wait4(), and likewise need not allow PLT interposing on

16bf8dd6dc Don't check the return value from self_reloc(), it can't fail and doesn't
return a value.

Despite what I said in my prior commit, it turns out this one platform
was checking the return value from the old self-reloc code (which returned
a hard-coded 0).

5b1c03fd13 The self-relocation code is not efi-specific, move it to boot/common.
The function was defined as taking 4 parameters and returning EFI_STATUS,
but all existing callers (in asm code) passed only two parameters and don't
use the return value. The function signature now matches that usage, and
doesn't refer to efi-specific types.

Parameters and variables now use the cannonical typenames set up by elf.h
(Elf_Word, Elf_Addr, etc) instead of raw C types. Hopefully this will
prevent suprises as new platforms come along and use this code.

The function was renamed from _reloc() to self_reloc() to emphasize its
difference from the other elf relocation code found in boot/common.

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.

* Intel 5100, STA mode
* AR5416, STA mode

3265af355a Attempt to address Bug - 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.
