Add a macro to invalidate the TLB for a given pmap/va pair. TLB
...
invalidation algorithm:
if (old mapping had PG_ASM set || pmap is active) {
TIBS(va);
if (also sync I-stream)
imb();
}
The check for "old mapping had PG_ASM" will get all kernel mappings (since
kernel mappings always have PG_ASM set).
This allows us to remove the bogus check for the kernel pmap in
active_pmap() - do so.
Use the new TLB invalidation macro whenever such action is needed.

Change active_pmap() to use the CPU mask (XXX and check for kernel pmap

as well, until some other changes are made). Nuke active_user_pmap(),
and change the places that used it to use active_pmap() instead (as well
as make some DIAGNOSTIC consistency checks).

Optimize out a TLB invalidation in a common case of pmap_enter(): if
...
the PTE was previously invalid, no TLB invalidation is necessary because:
(1) when a PTE is invalidated, its entry is flushed from the
TLB
(2) the PALcode won't install an invalid PTE into the TLB.

- Make MACHINE_NEW_NONCONTIG non-optional.
...
- Maintain two copies of the number and size of physical memory segments.
One copy, mem_clusters[], contains _all_ of physical RAM, for crash dumps.
The other copy, phys_seg_list[], starts out with all of physical RAM (and
is used to initialize mem_clusters[]), but is adjusted to be the memory
actually managed by the VM system.
- Fix computation of physmem; when support for MACHINE_NEW_NONCONTIG was
added, physmem was accidentally changed to not take into account the memory
located before the kernel, or the memory taken up by the kernel itself.
