a3b8e6c9c7 Move the definition of ElfN_Hashelt to common headers. The only platform 
which has a different definition for this is alpha.

ae97f0c60a Remove an assertion as to whether the current thread already had the FPU or 
not.  It may be desirable to put something similar back, but it's getting in
the way in it's current form.

4fc9c21665 - Move macros that represent where syscall args are kept in a trapframe from 
trap.c to frame.h
- Use the macros in vm_machdep.c:cpu_fork() to set up the trap frame of the

d7323955b4 Get the correct memory regions from OpenFirmware. We were getting the 
"available" ranges, not the "physical" ranges.  Clean up some of the
bootstrap code in the process.

88bdee3b2f Make the run queue parameters machine dependent. Optimize 64 bit 
architectures by using a 64 bit word for the bit array which keeps
track of non-empty queues.

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)

56d625090e 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.

3d8c7d4cab Pass vm_page_t instead of physical addresses to pmap_zero_page[_area]() 
and pmap_copy_page().  This gets rid of a couple more physical addresses
in upper layers, with the eventual aim of supporting PAE and dealing with
the physical addressing mostly within pmap.  (We will need either 64 bit
physical addresses or page indexes, possibly both depending on the
circumstances.  Leaving this to pmap itself gives more flexibilitly.)
