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.

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.

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.

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.
system calls now enter without Giant held, and then in some cases, acquire

Remove a number of other MPSAFE annotations in the credential code and
tweak one or two other adjacent comments.
Add some comments to explain how 10 was picked. 20 was completely
arbitrary, at least 10 has some reasoning behind it.
Also, update the comments about how long we sleep to reflect the new,
shorter timeout we use.
- Remove unnecessary findcpuspeed() function.
- Initialize the timer_freq in i8254_init().
- Fix inittodr() and resettodr(). These are broken by rev.1.154.
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.

specifies the offset at which the timestamp should be inserted.
NG_SOURCE(4) gives an example usage that queues an ICMP packet. Using that
example, the following command will insert a timestamp in the ICMP's data
payload:
ngctl msg src0: settimestamp '{ offset=0x2a flags=1 }'
