Some PROMs get really uneasy if the prom_reboot() function is called
...
after the other CPUs have already return into the PROM through prom_cpustop().
So don't do it; try to halt the other CPUs only when an actual `halt'
is requested.
My guess in this case is that the PROM does not expect its original boot
CPU to call prom_cpustop(0), or possibly treats it as the equivalent of
a prom_halt() which is then called again by some other CPU. In any case,
the result is garbage.

0d8f526f58
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.

Add the MIPS3_CONFIG_SE (name taken from Rm52xx manual) bit, which is the
...
external cache enable bit -- this allows software to enable or disable the
(external) L2 cache on the R5k and Rm527x and the (external) L3 cache on
the Rm7k. If the (external) cache is disabled, treat it as if there were
no cache for the purposes of the cache setup code.
Also, update sgimips code to use the new name.
