b23619e02a Deorbit suibyte(). It was only used for split address space systems 
for supporting UIO_USERISPACE (ie: it wasn't used).

2f9267ec23 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().

99cca534f3 - 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.

b57e802a85 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.

db17c6fc07 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)

d297ad160e Don't use the symbol name to lookup the symbol value when we can use 
the symbol index defined by the relocation. The elf_lookup() support
function is to be used by elf_reloc() when symbol lookups need to be
done. The elf_lookup() function operates on the symbol index and
will do a symbol name based lookup when such is required, otherwise
it uses the symbol index directly. This solves the problem seen on
ia64 where the symbol hash table does not contain local symbols and
a symbol name based lookup would fail for those symbols.

Don't pass the symbol name to elf_reloc(), as it isn't used any more.
