fix two bugs in my last pmap rework:
...
- in tlb_flush_all(), don't skip TLB entries with the high bit on,
I was confused about which MMU register it was using. it's also fine
to use the last hardware context.
- in pmap_create(), don't allocate a hardware context for the new pmap.
it's unnecessary, and when this would cause us to recycle all the contexts,
it would result in the current process's context being set to 0
(ie. the kernel's context). the current process could then return to
userspace without going through the context-switch code (and thus without
having a hardware context reallocated). this would lead to user mappings
being entered in the kernel's context later, causing all sorts of trouble.
add some assertions to catch this kind of thing.

Change the bootstrap procedure to avoid temporarily mapping physical memory.
...
Now, on the Amiga, we copy a small piece of code to chip memory and enable the
MMU from here.
On the DraCo, we setup %itt0 so that we shadow physical memory without
touching the page tables and very temporarily. The DraCo's memory layout
guarantees that there is no overlap in this case between physical and
virtual addresses.
This fixes a bug where Amiga's with physical memory at 0x200000 wouldn't boot
kernels >2M in size, and possibly other corner cases.
Joint work with Ilpo Ruotsalainen and Ignatios Souvatzis.

keep track of which cpu's have run a pmap and only broadcast tlb flushes to
...
cpu's who have done so. implement pmap_deactivate() for MULTIPROCESSOR and
call it from cpu_switch() when we are about to switch proces and when we
enter idle().
with this change, i see significantly reduced tlb IPI traffic and fork/exec
bound processes -- such as "configure" -- run significantly faster, upto
15%. i also obvserved a small (0-2%) benefit to CPU bound tasks as well.
