0c883cef45 Major GEOM MULTIPATH class rewrite:
- Improved locking and destruction process to fix crashes.
 - Improved "automatic" configuration method to make it consistent and safe
by reading metadata back from all specified paths after writing to one.
 - Added provider size check to reduce chance of ordering conflict with
other GEOM classes.
 - Added "manual" configuration method without using on-disk metadata.
 - Added "add" and "remove" commands to allow manage paths manually.
 - Failed paths are no longer dropped from geom, but only marked as FAIL
and excluded from I/O operations.
 - Automatically restore failed paths when all others paths are marked
as failed, for example, because of device-caused (not transport) errors.
 - Added "fail" and "restore" commands to manually control FAIL flag.
 - geom is now destroyed on last path disconnection.
 - Added optional Active/Active mode support. Unlike Active/Passive
mode, load evenly distributed between all working paths. If supported by
the device, it allows to significantly improve performance, utilizing
bandwidth of all paths. It is controlled by -A option during creation.
Disabled by default now.
 - Improved `status` and `list` commands output.

0f1aca6519 A default route learned from the RAs could be deleted manually
after its installation. This removal may be accidental and can
prevent the default route from being installed in the future if
the associated default router has the best preference. The cause
is the lack of status update in the default router on the state
of its route installation in the kernel FIB. This patch fixes
the described problem.

e18783345a To send a frame, controller requires a prepended TX header and
the length of frame should be treated as multiple of 4. Actual
frame length is set in the TX header. The TX header position
should be aligned on 4 byte boundary and actual frame start
position should be aligned on 4 byte boundary as well. This means
we need 4(TX header length) + 3(frame length fixup) additional free
space in TX buffer in addition to actual frame length.
Make sure TX handler check these additional bytes.
ae_tx_avail_size() returns actual free space in TX buffer to ease
the calculation of available TX buffer space in caller. While I'm
here, replace magic number to appropriate sizeof operator to
enhance readability.

This change should fix controller lockup issue happened under
certain conditions but it still does not fix watchdog timeout. It
seems the watchdog timeout is side-effect of TxS and TxD
mismatches. The root cause of TxD/TxD mismatch is not known yet but
it looks like silicon bug. I guess driver may have to reinitialize
controller whenever it sees TxS and TxD mismatches but leave it as
it was at this moment.

cddcb8b4dc On i386, fbt probes are implemented by writing an invalid opcode over
certain instructions in a function prologue or epilogue.  DTrace has a
hook into the invalid opcode fault handler that checks whether the fault
was due to an probe and if so, runs the DTrace magic.

Upon returning from an invalid opcode fault caused by a probe, DTrace must
emulate the instruction that was replaced with the invalid opcode and then
return control to the instruction following the invalid opcode.

There were a pair of related bugs in the emulation for the leave
instruction.  The leave instruction is used to pop off a stack frame prior
to returning from a function.  The emulation for this instruction must
move the trap frame for the invalid opcode fault down the stack to the
bottom of the stack frame that is being removed, and then execute an iret.

At two points in this process, the emulation code was storing values above
the current value of the stack pointer.  This opened up a window in which
if we were two take an interrupt, the trap frame for the interrupt would
overwrite the values stored on the stack, causing the system to panic
later.

The first bug was that at one point the emulation code saves the new value
for $esp above the current stack pointer value.  The fix is to save this
value instead inside of the original trap frame.  At this point we do
not need the original trap frame so this is safe.

The second bug is that when the emulate code loads $esp from the stack, it
points part-way through the new trap frame instead of at its beginning.
The emulation code adjusts the stack pointer to the correct value
immediately afterwards, but this still leaves a one instruction window in
which an interrupt would corrupt this trap frame.  Fix this by adjusting
the stack frame value before loading it into $esp.

This fixes panics in invop_leave on i386 when using fbt return probes.

2e0aa47581 The generated Makefile for the kernel was not running ctfconvert on
object files corresponding to source files that had the compile-with
option set in conf/files.  This means that any fbt probes for functions
in that object file would not have correct argument types.

The fix is to run ctfconvert on any target file that does not have the
no-obj option set in files.

907eed1f50 Revert r227403 for now. Since the cross-tools stage purposefully
doesn't have ${WORLDTMP}/usr/bin in its PATH, if you build world with
CC=clang, tblgen tools from /usr/bin will be used instead of the ones
built under ${WORLDTMP}.  This can lead to various errors, especially if
you upgrade from an older clang.

Note that building world with gcc would not experience these problems,
because it only uses the tblgen tools in the world stage, where PATH
does contain ${WORLDTMP}/usr/bin.

cf5d42d4b0 Bump this up to where it used to be.
I need to investigate this a little closer, but it seems that in noisy
environments the NF load takes longer than 5 * DELAY(10) and this is
messing up future NF calibrations. (The background: NF calibrations
begin at the value programmed in after the load has completed, so
if this is never loaded in, the NF calibrations only ever start at
the currently calibrated NF value, rather than starting at something
high (say -50.)

More investigation about the effect on 11n RX and calibration results
are needed.

ddbe3036e5 Introduce a work-around for issues with the AR5416 based MAC on SMP devices.
The AR5416 MAC (which shows up in the AR5008, AR9001, AR9002 devices) has
issues with PCI transactions on SMP machines. This work-around enforces
that register access is serialised through a (global for now) spinlock.

This should stop the hangs people have seen with the AR5416 PCI devices
on SMP hosts.

338f97fe8d Move building of clang's tblgen tools (and required libraries) from the
bootstrap-tools stage to the cross-tools stage.  These tools are only
needed for generating llvm/clang include files, and are not necessary
for bootstrapping the build itself.

This shaves off some build time, because the required libraries are now
just built twice (during the cross-tools and world stages), instead of
three times.

Also, if you build world using WITHOUT_CLANG= in src.conf(5), no llvm or
clang code will be compiled at all anymore.

38962489b3 If software retransmit occurs with an ath_buf marked ATH_BUF_BUSY,
it's cloned and that clone is retransmitted. This means that the
ath_buf pointer squirreled away on the baw window array is suddenly
wrong and was causing all kinds of console output.

This updates the pointer in that particular BAW slot to the new
ath_buf after ensuring that:

* the new and old buffers have the same seqno;
* the current slot pointer matches the old buffer pointer.

This quietens the debugging output (again), restoring said debugging
to only signify when a broken condition has occured.

009d7740fc Flip on processing interrupt profile events for mips24k.
This is a bit hackish and should be made more generic (ie, support more than
two hard-coded performance counter+config register pairs) so it can be used
for mips74k and other chips.

All this does is process the initial interrupt event. It doesn't (yet) handle
callgraph events, so even if you route the exception/interrupt to this routine
and flip the bit on, it will hang and crash pmc unless you disable callgraph
support when you enable a sample based PMC.
