a9093e846d Move macros describing extended attributes in UFS from
<sys/extattr.h> to <ufs/ufs/extattr.h>. Move description
of extended attributes in UFS from man9/extattr.9 to
man5/fs.5.

Note that restore will not compile until <sys/extattr.h>
and <ufs/ufs/extattr.h> have been updated.

dc3a205bc4 Better fix for the errors under high load. Returning CAM_SCSI_BUSY is almost
never correct as CAM has no real understanding of it, and will just immediately
retry the command.  This leads to undesirable cycling of the camisr as well as
a high possibility for the command to exhaust its retries before the driver
can get around to servicing it.

The better fix, as demonstrated here, is to freeze the simq and mark the
command as needing to be tried.  Then when driver can service the command,
the simq gets unfrozen.  This is correct, and documented here to help reduce
the mystery.  However, it also points out a shortcoming in CAM error handling
that makes writing drivers harder.

8da3fc95a7 Acquiring smp_ipi_mtx on every call to pmap_invalidate_*() is wasteful.
For example, during a buildworld more than half of the calls do not
generate an IPI because the only TLB entry invalidated is on the calling
processor.  This revision pushes down the acquisition and release of
smp_ipi_mtx into smp_tlb_shootdown() and smp_targeted_tlb_shootdown() and
instead uses sched_pin() and sched_unpin() in pmap_invalidate_*() so that
thread migration doesn't lead to a missed TLB invalidation.

4d44d81742 Check the _TMP value for sanity also. On some systems (HP NX laptops), the
EC occasionally times out and provides bogus values (3000C).  This change
prevents those systems from prematurely shutting down while we work on the
underlying problem.  Also, bump the sanity value to 0...200C from 0...150C.

d78180f8f5 Partial fix for a bug in rev.1.231. If suspend/resume clobbers the
RTC state, then it may clobber the RTC index register, so the index
register must be restored before using it to restore control registers
in rtc_restore().

The following problems remain:
- rtc_restore() is only called if pmtimer is configured.  Buggy
  suspend/resumes are more likely to clobber the index register than
  a control register, so pmtimer is more needed than it used to be.
- pmtimer doesn't exist for amd64.
- Restoring of the RTC state may race with rtcintr().  If an RTC
  interrupt is handled before the state is restored, then rtcin(RTC_INTR)
  in rtcintr() may read from the wrong register, so rtcintr() may spin
  forever.  This may be mitigated by the most common state clobbering
  being to turn off RTC interrupts.

59a0d28bac Catch up the rest of the drivers with the ether_vlan_mtap modifications.
If these drivers are setting M_VLANTAG because they are stripping the
layer 2 802.1Q headers, then they need to be re-inserting them so any
bpf(4) peers can properly decode them.

It should be noted that this is compiled tested only.
