8253dcabe7 Fix a problem when CARP is enabled on the interface for IPv4
but not for IPv6.  The current checks in nd6_nbr.c along with the
old version will result in ifa being NULL and subsequently the
packet will be dropped.  This prevented NS/NA, from working and
with that IPv6.

Now return the ifa from the carp lookup function in two cases:
1) if the address matches, is a carp address, and we are MASTER
   (as before),
2) if the address matches but it is not a carp address at all (new).

3f6e7b9b11 Add rmb() to tsc_read_##x to enforce serialization of rdtsc captures.
Intel Architecture Manual specifies that rdtsc instruction is not serialized,
so without this change, TSC synchronization test would periodically fail,
resulting in use of HPET timecounter instead of TSC-low.  This caused
severe performance degradation (40-50%) when running high IO/s workloads due to
HPET MMIO reads and GEOM stat collection.

Tests on Xeon E5-2600 (Sandy Bridge) 8C systems were seeing TSC synchronization
fail approximately 20% of the time.

52baf267be Update to latest git version of dtc to get new dtsv2 support,
including the include directive.

Fix minor build issue corrected by converting yypush_buffer_state and
yypop_buffer_state to yy_set_buffer_state and a hard-coded 100-deep
stack.  It was easier to fix it here than to import that support into
our flex.

The new tools and test hardness remain unsupported at the moment.

b225878c75 Quirk MS keyboard so that function keys work
The function keys on a Microsoft Natural Egronomic Keyboard 4000 have been
repurposed as "Help", "Undo", "Redo" etc., and a special "F Lock" key is
required to return them to their normal purpose.

This change enables the UQ_KBD_BOOTPROTO quirk for the MS Natural 4000
keyboard to get the keys working again.  More extensive changes to the USB
keyboard infrastructure would be needed to fully support the "F Lock" mode
and the extended keys on this keyboard.

700de5109a The PT_I386_{GET,SET}XMMREGS and PT_{GET,SET}XSTATE operate on the
stopped threads. Implementation assumes that the thread's FPU context
is spilled into the PCB due to stop. This is mostly true, except when
FPU state for the thread is not initialized. Then the requests operate
on the garbage state which is currently left in the PCB, causing
confusion.

The situation is indeed observed after a signal delivery and before
#NM fault on execution of any FPU instruction in the signal handler,
since sendsig(9) drops FPU state for current thread, clearing
PCB_FPUINITDONE. When inspecting context state for the signal handler,
debugger sees the FPU state of the main program context instead of the
clear state supposed to be provided to handler.

Fix this by forcing clean FPU state in PCB user FPU save area by
performing getfpuregs(9) before accessing user FPU save area in
ptrace_machdep.c.

Note: this change will be merged to i386 kernel as well, where it is
much more important, since e.g. gdb on i386 uses PT_I386_GETXMMREGS to
inspect FPU context on CPUs that support SSE. Amd64 version of gdb
uses PT_GETFPREGS to inspect both 64 and 32 bit processes, which does
not exhibit the bug.
