21ef14008d Add SMP aware cache flushing functions, which operate on a single physical
page.  These send IPIs if necessary in order to keep the caches in sync on
all cpus.

6aad34df02 Add a support macro to convert the 5-bit packed register field of
a floating point instruction into a 6-bit register number for
double and quad arguments.
Make use of the new INSFPdq_RN macro where apporpriate; this
is required for correctly handling the "high" fp registers
(>= %f32).
Fix a number of bugs related to the handling of the high registers
which were caused by using __fpu_[gs]etreg() where __fpu_[gs]etreg64()
should be used (the former can only access the low, single-precision,
registers).

d6121aa92f Make a macro for the guts of tl0_immu_miss, like dmmu_miss and prot.
Rearrange things slightly so that the contents of the tag access
register are read and restored outside of the macros.  The intention
is to pass the page size to look up as an argument to the macros.

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.

6965731537 Check the alignment of the stack pointer before copying in windows from the
user stack in response to a failed window fill, allowing the process to be
killed if its wrong.  This caused user programs which misalign their stack
pointer to get stuck in an infinite loop at the kernel-userland boundary,
which is mostly harmless.

The same thing causes a fatal RED state exception on OpenBSD and probably
NetBSD.

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.)

a72383027f Rename some fields in struct frame to be compatible with NetBSD/OpenBSD,
and add some compatibility defines.  Add fields for ins and locals to
struct reg also for the same reason; these aren't filled in yet because
getting at those registers sucks and I'd rather not save them in the
trapframe just for this.  Reorder struct reg to be ABI compatible as
well.  Add needed include of machine/emul.h.

This gets pmdb (poor man's debugger) from OpenBSD mostly compiling but it
doesn't work yet :(

14ae95f735 Moved signal handling and rescheduling from userret() to ast() so that
they aren't in the usual path of execution for syscalls and traps.
The main complication for this is that we have to set flags to control
ast() everywhere that changes the signal mask.

Avoid locking in userret() in most of the remaining cases.

  and initializing MI mutexes.  Change the various MD startup routines
  to call this function instead of duplicating all the code themselves.

3ac364813a Fix crashes that would happen when more than one 4MB page was used to
hold the kernel text, data and loader metadata by not using a fixed slot
to store the TSB page(s) into. Enter fake 8k page entries into the kernel
TSB that cover the 4M kernel page(s), sot that pmap_kenter() will work
