ffc4969f6e Don't count many items as EVCNT_TYPE_INTR because they clutter up the
systat vmstat display.

104cf0ae89 Add support for kernel preeemption to the i386 and amd64 ports. Notes:
- I have seen one isolated panic in the x86 pmap, but otherwise i386
  seems stable with preemption enabled.

- amd64 is missing the FPU handling changes and it's not yet safe to
  enable it there.

- The usual level for kern.sched.kpreempt_pri will be 128 once enabled
  by default. For testing, setting it to 0 helps to shake out bugs.

9c1818760e - Make some entry/exit points preemption safe.
- Try to avoid mispredicted bracnhes in Xsyscall.
- Interrupts were being enabled in Xsyscall _after_ checking for ASTs,
  while could have resulted in ugly behaviour like delayed signals or
  context switches. Fix it.

01fba5909d Add floppy support to prep (the croud goes wild)
Add an additional argument to pnpbus_intr_establish to allow overriding of
the pnp interrupt type, because some devices lie.
Change how the pnpbus match routine works, to avoid attaching it when we
are probing for cpu's.
Fix a few stray printf's in the autoconf output.

7c334139cd - mutex_spin_enter: avoid SPL NOT LOWERED... errors when running with
preemption. This could also fix similar errors seen with softints.
- Adjust code slightly to try and avoid mispredicted branches. The branch
  hint prefixes are apparently of little use.

27168d9d58 - Rename crit_enter/crit_exit to kpreempt_disable/kpreempt_enable.
DragonflyBSD uses the crit names for something quite different.
- Add a kpreempt_disabled function for diagnostic assertions.
- Add inline versions of kpreempt_enable/kpreempt_disable for primitives.
- Make some more changes for preemption safety to the x86 pmap.
