alpha: __cpu_simple_lock audit.

Add missing "cc" and "memory" asm clobbers to the compiler can't
reorder memory access around these.  The necessary memory barrier
instructions, mb, already appear in all the right places.

__cpu_simple_lock(9): Omit needless barriers in init.

It is, and always has been, the caller's responsibility to ensure the
lock is initialized before it can be used -- otherwise the memory
could hold garbage; it is nonsensical to even attempt locking
operations on it before initialization.

So there's no need to issue explicit barriers here.  The barrier
seems to have been introduced in sys/arch/alpha/alpha/lock_machdep.c
rev. 1.1 (since moved to inline asm in alpha/include/lock.h) and then
copied & pasted into several other architectures.

Fix an IPI deadlock scenario that resulted in a TLB shootdown timeout
panic reported by John Klos on port-alpha:

- pmap_tlb_shootnow(): If we acquire a pmap's activation lock, we will
  have raised the IPL on the current CPU to IPL_SCHED until we drop
  the tlb_lock (due to how nested spin mutexes work).  As such, when
  we release the activation lock, forcibly lower our IPL back to IPL_VM
  so that we can receive and process IPIs while waiting for other CPUs
  to process the shootdowns.
- mutex_vector_enter(): Invoke SPINLOCK_SPIN_HOOK while spinning to acquire
  a spin mutex.  This is a nop on most platforms, but it's important on
  the Alpha.  Without this, IPIs (and thus TLB shootdowns) cannot be
  processed if trying to acquire an IPL_SCHED spin mutex such as those
  used by the scheduler.

...and while we're poking around in here:

- Rework the Alpha SPINLOCK_SPIN_HOOK to only check curcpu()->ci_ipis
  if the current CPU's IPL is >= IPL_CLOCK (thus ensuring that preemption
  is disabled and thus guaranteeing that curcpu() is stable).  (Alpha does
  not yet support kernel preemption, but this is now one less thing that
  would need to be fixed.)

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.

SPINLOCK_INTERLOCK_RELEASE_HOOK should actually be
SPINLOCK_SPIN_HOOK, so that we actually check for
pending IPIs on the Alpha more than once.  Also,
when we call alpha_ipi_process(), make sure to go

On the Alpha, interprocessor interrupts come in at the same priority
as normal device interrupts.  Because of this, we won't get IPIs while
servicing such interrupts.  This can lead to the following deadlock
scenario as reported by Bill Sommerfeld:
- Process runs on cpu1, but has FP state on cpu0.
- Process executes FP-using insn, causing an FP trap, which causes
  the kernel lock to be acquired.
- At roughly the same time, cpu0 receives a device interrupt, and attempts
  to acquire the kernel lock, which blocks since cpu1 already has it.
- cpu1 sends cpu0 a SYNCH FPU IPI, and waits for cpu0 to release its
  FP state.
- Since cpu0 cannot notice the IPI until it has processed the device
  interrupt, which it cannot do because it cannot acquire the kernel
  lock, we have deadlock.

Solve the problem by adding a spinlock interlock release hook which
checks for pending IPIs and processes them.

Idea from Bill Sommerfeld.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Require that each each MACHINE/MACHINE_ARCH supply a lock.h.  This file
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED.  These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case).  Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.

These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.
