skrll | Adjust egister usage so that r4 and r5 are preserved as cur{cpu,lwp}
respectively as required by the change to make ASTs operate per-LWP
rather than per-CPU. DO_AST_AND_RESTORE_ALIGNMENT_FAULTS expects this.
Remove the call to dosoftints while I'm here as it's dont in DO_AST...

Interrupt handling changes, in discussion since February:
- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.

Merge the ppcoea-renovation branch to HEAD.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

In irq_setmasks(), refer spl_masks[current_spl_level] directly
rather than spl_mask which is a saved value in splraise() and
splx() functions because the latter one is not always sync'ed with
current_spl_level and interrupt state could be mangled.
Okay'ed by chris@, and should close PR port-shark/22355.

Rewrite the ARM mutex implementation to be of the simple-mutex variety.
Because pre-v6 ARM lacks support for an atomic compare-and-swap, we
implement _lock_cas() as a restartable atomic squence that is checked
in the IRQ handler right before AST processing. (This is safe because,
for all practical purposes, there are no SMP pre-v6 ARM systems.)
This can serve as a model for other non-MP platforms that lack the
necessary atomic operations for mutexes (SuperH, for example).
Upshots of this change:
- kmutex_t is now down to 8 bytes on ARM; about as good as we can get.
- ARM2 systems don't have to trap and emulate SWP or SWPB for mutexes.
The acorn26 port is not updated by this commit to do the LOCK_CAS_CHECK.
That is left as an exercise for the port maintainer.
Reviewed and tested by Matt Thomas.

Continue the " - . - 8" purge. Specifically:
add rd, pc, #foo - . - 8 -> adr rd, foo
ldr rd, [pc, #foo - . - 8] -> ldr rd, foo
Also, when saving the return address for a function pointer call, use
"mov lr, pc" just before the call unless the return address is somewhere
other than just after the call site.
Finally, a few obvious little micro-optimisations like using LDR directly
rather than ADR followed by LDR, and loading directly into PC rather than
bouncing via R0.

Kill arch/arm32. The last platform supported there, Shark, is now
in arch/shark.
(NOTE: arch/dnard, a premature move to split out the Shark support
code, is going to be deleted. It has bit-rotted.)

sys/arch/shark/isa/isa_irq.S: revision 1.8

Make clockintr() return 1 since it's always handled so that
clock interrupt is properly acounted by evcnt(9) in isa_irq.S.
In irq_setmasks(), refer spl_masks[current_spl_level] directly
rather than spl_mask which is a saved value in splraise() and
splx() functions because the latter one is not always sync'ed with
current_spl_level and interrupt state could be mangled.

Remove _SPL_* aliases.
Don't store irqmasks in ci_cpl, just make it an ipl level.
