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.

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).

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.

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.
