6c2607ad88 Many fixes to low-level trap and interrupt handling: 
- Tidy up clock code.  Don't repeatedly call hardclock().
- Remove intrnames, decrnest and intrcnt from locore.s
- Coalesce all trap handling into a single stub that then calls a dispatch
  function.

e102a9b6dd Add an MD callout like cpu_exit, but which is called after sched_lock is 
obtained, when all other scheduling activity is suspended.  This is needed
on sparc64 to deactivate the vmspace of the exiting process on all cpus.
Otherwise if another unrelated process gets the exact same vmspace structure
allocated to it (same address), its address space will not be activated
properly.  This seems to fix some spontaneous signal 11 problems with smp
on sparc64.

df4ec1a7b3 Deorbit suibyte(). It was only used for split address space systems 
for supporting UIO_USERISPACE (ie: it wasn't used).

4830c34648 Move the "- 1" into the RQB_FFS(mask) macro itself so that 
implementations can provide a base zero ffs function if they wish.
This changes
  #define RQB_FFS(mask) (ffs64(mask))
  foo = RQB_FFS(mask) - 1;
to
  #define RQB_FFS(mask) (ffs64(mask) - 1)
  foo = RQB_FFS(mask);
On some platforms we can get the "- 1" for free, eg: those that use the
C code for ffs64().

2aa855d8b1 - Fixup / remove obsolete comments. 
- ktrace no longer requires Giant so do ktrace syscall events before and
  after acquiring and releasing Giant, respectively.
- For i386, ia32 syscalls on ia64, powerpc, and sparc64, get rid of the
  goto bad hack and instead use the model on ia64 and alpha were we
  skip the actual syscall invocation if error != 0.  This fixes a bug
  where if we the copyin() of the arguments failed for a syscall that
  was not marked MP safe, we would try to release Giant when we had
  not acquired it.

7b2f527b76 Commit of stuff that's been sitting in my tree for a while. 
Highlights include:
- New low-level trap code from NetBSD.  The high level code still needs a lot
  of work.
- Fixes for some pmap handling in thread switching.
- The kernel will now get to attempting to jump into init in user mode.  There
  are some pmap/trap issues which prevent it from actually getting there though.

c0e3147cc6 Tidy up some loose ends. 
i386/ia64/alpha - catch up to sparc64/ppc:
- replace pmap_kernel() with refs to kernel_pmap
- change kernel_pmap pointer to (&kernel_pmap_store)
  (this is a speedup since ld can set these at compile/link time)
all platforms (as suggested by jake):
- gc unused pmap_reference
- gc unused pmap_destroy
- gc unused struct pmap.pm_count
(we never used pm_count - we track address space sharing at the vmspace)
