55bd918aab o Remove the pmap argument to pmap_invalidate_all() as it's not used
other than in a potentially dangerous KASSERT.
o   Hand-inline pmap_remove_page() as it's only called from 1 place and
    the abstraction that pmap_remove_page() provides is not enough to
    warrant the obfuscation. Eliminate the dangerous KASSERT in the
    process.
o   In pmap_remove_pte(), remove the KASSERT for pmap being the current
    one as it's not safe in the face of CPU migration.

pam_end() already contains a NULL check, and it is not unreasonable to
call it with a NULL pamh in a cleanup / error-handling situation.  Remove
OPENPAM_NONNULL, which may cause gcc to optimize away the NULL check.

f73ddcd50b Drop the pmap argument to pmap_invalidate_page(). It's not used other
than in a KASSERT. The KASSERT is broken in that it's done outside the
critical section and as such isn't protected against CPU migration.
Improve pmap_invalidate_page() as follows:
o   calculate vhpt_ofs inside the critical region for exactly the same
    reason.
o   calculate the tag outside the FOREACH loop, as it's loop-invariant.
    This is more efficient.
o   Replace the test and set with an atomic cmpset operation because we
    are changing other CPU's VHPT tables and this avoids invalidating
    after the entry got modified. Not necessarily a problem, but better
    safe than sorry.

7bc8a5971b With preemption, the high FP registers may get enabled by cpu_switch()
before we grab the mutex. Don't assert that they must be disabled at
that point. We pretty much bypass all logic in that case anyway and
leave immediately, so there's no harm.

95b11053b3 Fix interrupt handling by extending the critical region so that
preemption doesn't happen until after all pending interrupt have
been services.
While here again, simplify the EOI handling by doing it after we
call the XIV-specific handlers, rather than in each of them. The
original thought was that we may want to do an EOI first and the
actual IPI handling next, but that's mostly a micro-optimization.

cc7a041c2b Disable interrupts when calling into SAL for PCI configuration
cycles. This serves 2 purposes:
1.  It prevents preemption and CPU migration while running SAL code.
2.  It reduces the chance of stack overflows: we're supposed to enter
    SAL with at least 16KB of either memory- or register stack space,
    which we can't do without switching to a different stack.

07e6e81e2f - The firmware of Sun Fire V1280 has a misfeature of setting %wstate to
7 which corresponds to WSTATE_KMIX in OpenSolaris whenever calling into
  it which totally screws us even when restoring %wstate afterwards as
  spill/fill traps can happen while in OFW. The rather hackish OpenBSD
  approach of just setting the equivalent of WSTATE_KERNEL to 7 also is
  no option as we treat %wstate as a bit field. So in order to deal with
  this problem actually implement spill/fill handlers for %wstate 7 which
  just act as the WSTATE_KERNEL ones except of theoretically also handling
  32-bit, turn off interrupts completely so we don't even take IPIs while
  in OFW which should ensure we only take spill/fill traps at most and
  restore %wstate after calling into OFW once we have taken over the trap
  table. While at it, actually set WSTATE_{,PROM}_KMIX before calling into
  OFW just like OpenSolaris does, which should at least help testing this
  change on non-V1280.
- Remove comments referring to the %wstate usage in BSD/OS.
- Remove the no longer used RSF_ALIGN_RETRY macro.
- Correct some trap table addresses in comments.
- Ensure %wstate is set to WSTATE_KERNEL when taking over the trap table.
- Ensure PSTATE_AM is off when entering or exiting to OFW as well as that
  interrupts are also completely off when exiting to OFW as the firmware
  trap table shouldn't be used to handle our interrupts.

c613313c10 Improve the KVA space sizing of 186682; on machines with large dTLBs we
can actually use all of the available lockable entries of the tiny dTLB
for the kernel TSB. With this change the KVA space sizing happens to be
more in line with the MI one so up to at least 24GB machines KVA doesn't
need to be limited manually. This is just another stopgap though, the
real solution is to take advantage of ASI_ATOMIC_QUAD_LDD_PHYS on CPUs
providing it so we don't need to lock the kernel TSB pages into the dTLB
in the first place.

Scrt1_c.o was accidentally compiled with -DGCRT (profiling), like gcrt1_c.o.
This problem is i386-specific, the other architectures are OK.

If you have problems with PIE executables such as samba and cups leaving

b28ad3ebc9 - While SPARC V9 allows tininess to be detected either before or after
rounding (impl. dep. #55), the SPARC JPS1 responsible for SPARC64 and
  UltraSPARC processors defines that in all cases tinyness is detected
  before rounding, therefore rounding up to the smallest normalised
  number should set the underflow flag.
- If an infinite result is rounded down, the result should have an
  exponent 1 less than the value for infinity.
