e9d8b9c383 This update primarily addresses the ability to have both the em
and the igb driver static in the kernel. But it also reflects
some other bug fixes in my development stream at Intel.
PR 122373 is also fixed in this code.

53eb99795c Back out revision 1.6, the addition of "BEFORE: mountcritremote".
mountcritremote REQUIREs FILESYSTEMS, and that script REQUIREs zfs,
so this change is a noop. By removing it we make life a little easier
both for rcorder(8) and for debugging down the road.

20c46652dc PR ports/121363 (& ports/73797) has been committed, so we can now go back
to JB's revision 1.96 change to remove -fno-strict-aliasing from CFLAGS.

This makes the default CFLAGS to match the simple defaults that the
tinderboxes use.  By using -fno-strict-aliasing by default we are
choosing to ignore problems in code which had the potential to
shoot ourselves in the foot.

8d809d5061 Implement per-cpu callout threads, wheels, and locks.
- Move callout thread creation from kern_intr.c to kern_timeout.c
 - Call callout_tick() on every processor via hardclock_cpu() rather than
   inspecting callout internal details in kern_clock.c.
 - Remove callout implementation details from callout.h
 - Package up all of the global variables into a per-cpu callout structure.
 - Start one thread per-cpu.  Threads are not strictly bound.  They prefer
   to execute on the native cpu but may migrate temporarily if interrupts
   are starving callout processing.
 - Run all callouts by default in the thread for cpu0 to maintain current
   ordering and concurrency guarantees.  Many consumers may not properly
   handle concurrent execution.
 - The new callout_reset_on() api allows specifying a particular cpu to
   execute the callout on.  This may migrate a callout to a new cpu.
   callout_reset() schedules on the last assigned cpu while
   callout_reset_curcpu() schedules on the current cpu.

d6e0eb0a48 Replace function _umtx_op with _umtx_op_err, the later function directly
returns errno, because errno can be mucked by user's signal handler and
most of pthread api heavily depends on errno to be correct, this change
should improve stability of the thread library.

bc8a0d87bd Optimize pmap_pml4e() and pmap_pdpe() based upon two observations: The
given pmap is never NULL, and therefore pmap_pml4e() can never return
NULL.  The pervasive use of these inline functions throughout the pmap
makes these simple changes worthwhile.

55aa113659 Calling RequestSupplementAdapterInfo before RequestAdapterInfo appears
to trip a bug causing the latter to return a zeroed struct
aac_adapter_info.  This causes two issues.  One is cosmetic only --
a verbose boot prints information about the controller, and shows all
zero:

aac0: Unknown processor 0MHz, 0MB memory (0MB cache, 0MB execution),
  unknown battery platform

The second problem is that the firmware version information is stored
away for aac_rev_check, for userland tools (like aaccli) to query via
the FSACTL_MINIPORT_REV_CHECK and FSACTL_LNX_MINIPORT_REV_CHECK ioctls.
When aaccli encounters this issue it prints

Command Error: <The current AFAAPI.DLL is too old to work with the
  current controller software.>

Move the RequestSupplementAdapterInfo call after RequestAdapterInfo,
which seems to fix both problems.

These functions try the specified operation (rlocking and wlocking) and
true is returned if the operation completes, false otherwise.

manpage updating will happen soon.

e955d4fd10 The MPT driver treats the "core" module with the same importance and
abstraction as the RAID and CAM modules, making it nearly impossible
for enough initialization to be done in time for the RAID module to
know whether to attach.  On top of this, no reset was being done on
the controller on attach, in violation of the spec.  Additionally,
the port enable step was being deferred to the end of the attach
process, long after it should have been done to ensure reliable
operation from the controller.  Fix all of these with a few hacks
to force the "attach" and "enable" steps of the core module early
on, and ensure that a reset and port enable also happens early on.
In the future, the driver needs to be refactored to eliminate the
core module abstraction, clean up withe reset/enable steps, and
defer event messages until all of the modules are available to
recieve them.
