ee71ea68bc microSPARC-IIep is a sun4m but with an integrated PCI controller. 
In a lot of places (like pmap &c) we want it to be treated as SUN4M.
But since various low-level things are done very differently from
normal sparcs (and since for now it requires a relocated kernel
anyway), the MSIIEP kernels are not supposed to support any other
system.  So when MSIIEP is defined - insist on SUN4M defined and SUN4
and SUN4C not defined.

88ff68974a Changes from Martin Husemann and myself: 
- Make the 32-bit SPARC profile support work with the GCC 2.95.3
  SPARC ELF compiler, which uses a different name for mcount.
- Make the 64-bit SPARC profile support header look more like the 32-bit
  SPARC header (no functional change -- 64-bit SPARC already used the
  correct mcount name).

e727e3f180 Split elf32 vs. elf64 handling in loadfile(), including support for 
each separately and explicitly.  BOOT_ELF is now BOOT_ELF32 and
BOOT_ELF64, and ELFSIZE should no longer be defined in loadfile_machdep.h.

0e7661f023 Update pmap_update to now take the updated pmap as an argument. 
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

2b27ac7a99 Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for 
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.
