ad | pmap_remove_all(): Return a boolean value to indicate the behaviour. If
true, all mappings have been removed, the pmap is totally cleared out, and
UVM can then avoid doing the work to call pmap_remove() for each map entry.
If false, either nothing has been done, or some helpful arch-specific voodoo
has taken place.

rin | Retire tlbpid_t (u_short):
- PID (ctx, ASID) is 8-bit length, not half word.
- For struct pmap, no need to use integer types smaller than word as
pm_ctx because of alignment.
- For ppc4xx_tlb_enter(), we need word-length storage for pid (and msr).
XXX
Better to rewrite pmap module with more suggestive integer types rather
than char, int, long, and so on.

Modify mapiodev to take a third argument indicating whether the space
should be prefetchable (true) or not (false).

matt | PowerPC now exports a common view of cpu.h, vmparam.h and pmap.h
when building a MODULAR kernel or compiling _MODULE.
It should be noted that MODULAR or _MODULE export a view of the kernel
as being MULTIPROCESSOR (even if isn't).
The shared pmap TLB uses mdpg in places where it used mdpg to avoid
deadly embrance inclusion problems.

matt | branches: 1.15.4;
Add support for BookE Freescale MPC85xx (e500 core) processors.
Add fast softint support for PowerPC (though only booke uses it).
Redo FPU/VEC support and add e500 SPE support.
Rework trap/intrs to use a common trapframe format.
Support SOFTFLOAT (no hardfloat or fpu emulation) for BookE.

pooka | branches: 1.14.6; 1.14.8;
Make pmap_kernel() a MI macro for struct pmap *kernel_pmap_ptr,
which is now the "API" provided by the pmap module. pmap_kernel()
remains as the syntactic sugar.
Bonus cosmetics round: move all the pmap_t pointer typedefs into
uvm_pmap.h.
Thanks to Greg Oster for providing cpu muscle for doing test builds.

Replace the Mach-derived boolean_t type with the C99 bool type. A
future commit will replace use of TRUE and FALSE with true and false.

chs | branches: 1.10.8;
implement pmap_wired_count(). fix some places we would forget to splx().
move the parts of pte.h that were used into pmap.c (since they were really
pmap-internal details) and delete ibm4xx/pte.h. other misc cleanup.

chs | it really helps to get the stub right before cutting + pasting it 27 times.
alas, I did not. doh.
|

chs | add pmap_remove_all() hook (empty on most platforms so far).
|

eeh | pmap improvements:
Remove the cache flush routines that have been moved to cpu.c
Make sure we clear out the unused PA bits in the TTE which causes breakage
on some MMU models.

Add a port to IBM's PPC405GP Reference Board (the "walnut")
by Eduardo Horvath and Simon Burge of Wasabi Systems.
IBM 4xx series CPU features:
- New pmap and revised trap handler.
- Support on-chip timers, PCI controller, UARTs
- Framework for on-chip ethernet and watchdog timer.
General PowerPC features:
- Add in-kernel PPC floating point emulation
- New in{,4}_cksum that is between 1.5 and 5 times faster than the
old version depending on CPU type.
General changes:
- Kernel support for generic dbsym-style symbols.

sys/arch/powerpc/include/ibm4xx/tlb.h: revision 1.6
sys/arch/powerpc/include/ibm4xx/pmap.h: revision 1.20
Misc non-critical fixes.
- __asm --> __asm volatile for sure
- turn DEBUG code in __asm into DIAGNOSTIC code in C
- style
ppc4xx_tlb_enter(): invalidate entry after clearing MSR for sure.
pmap_procwr(): use dcbst instead of dcbf as a tiny optimization.
Retire tlbpid_t (u_short):
- PID (ctx, ASID) is 8-bit length, not half word.
- For struct pmap, no need to use integer types smaller than word as
pm_ctx because of alignment.
- For ppc4xx_tlb_enter(), we need word-length storage for pid (and msr).
XXX
Better to rewrite pmap module with more suggestive integer types rather
than char, int, long, and so on.
Fix pmap_procwr().
While we need to turn off IMMU, DMMU should be kept on. Otherwise,
dcbst (and also icbi probably, though not documented clearly both
for 405 and 403) should not work correctly.
