8131f8e4f6 boot: use -march=i386 for both i386 and amd64 builds
.. so that consistent compilation algorithms are used for both
architectures as in practice the binaries are expected to be
interchangeable (for time being).
Previously i386 used default setting which were equivalent to
-march=i486 -mtune=generic.
The only difference is using smaller but slower "leave" instructions.

1211b4598c Hide the unfortunate named sysctl kern.ipc.somaxconn from sysctl -a
output and replace it with a new visible sysctl kern.ipc.acceptqueue
of the same functionality.  It specifies the maximum length of the
accept queue on a listen socket.

The old kern.ipc.somaxconn remains available for reading and writing
for compatibility reasons so that existing programs, scripts and
configurations continue to work.  There no plans to ever remove the
orginal and now hidden kern.ipc.somaxconn.

807619d8ba - Give PIL_PREEMPT the lowest priority just above low/stray interrupts.
The reason for this is that the SPARC v9 architecture allows nested
  interrupts of higher priority/level than that of the current interrupt
  to occur (and we can't just entirely bypass this model, also, at least
  for tick interrupts, this also wouldn't be wise). However, when a
  preemption interrupt interrupts another interrupt of lower priority,
  f.e. PIL_ITHREAD, and that one in turn is nested by a third interrupt,
  f.e. PIL_TICK, with SCHED_ULE the execution of interrupts higher than
  PIL_PREEMPT may be migrated to another CPU. In particular, tl1_ret(),
  which is responsible for restoring the state of the CPU prior to entry
  to the interrupt based on the (also migrated) trap frame, then is run
  on a CPU which actually didn't receive the interrupt in question,
  causing an inappropriate processor interrupt level to be "restored".
  In turn, this causes interrupts of the first level, i.e. PIL_ITHREAD
  in the above scenario, to be blocked on the target of the migration
  until the correct PIL happens to be restored again on that CPU again.
  Making PIL_PREEMPT the lowest real priority, this effectively prevents
  this scenario from happening, as preemption interrupts no longer can
  interrupt any other interrupt besides stray ones (which is no issue).
  Thanks to attilio@ and especially mav@ for helping me to understand
  this problem at the 201208DevSummit.
- Give PIL_STOP (which is also used for IPI_STOP_HARD, given that there's
  no real equivalent to NMIs on SPARC v9) the highest possible priority
  just below the hardwired PIL_TICK, so it has a chance to interrupt
  more things.

766d50825e zfs: wait in arc_lowmem only if curproc == pageproc
... otherwise the current thread might be holding ARC locks and thus run
into a deadlock.  This happens, for example, when a thread does memory
allocation in the ARC code and runs into KVA shortage.
Also, it really makes the most sense to wait in pageproc, so that the
results of ARC reclamation are seen before the page cache is acted upon.
In other cases where vm_lowmem is invoked, e.g. on KVA space shortage,
the callers perform multiple attempts (up to 8) and wait for rather
long intervals between them (up to 4 seconds), so ARC reclaim results
should become visible even without explicit waiting on the ARC thread.

Note that this is not a critical issue for typical ZFS usages where KVA
space should already be large enough.  On amd64 systems setting KVA size
to twice the physical memory size is known to mitigate KVA fragmentation
issues in practice.

Side note: perhaps vm_lowmem 'how' parameter should be used to
differentiate between causes of the event.

b052199244 When checking to see if a video output's _ADR matches an entry in the
parent adapter's _DOD list, only check the low 16 bits of both _ADR and
_DOD.  The language in the ACPI spec seems to indicate that the _ADR values
should exactly match the entries in _DOD.  However, I assume that the
masking added to _DOD values was added to work around some known busted
machines (the commit history doesn't indicate either way), and the ACPI
spec does require that the low 16 bits are unique for all video outputs,
so only check the low 16 bits should be fine.

This fixes recognition of video outputs that use the new standardized
device ID scheme in ACPI 3.0 that set bit 31 such as certain Dell laptops.
