Write a NetBSD disklabel to 2nd sector while retaining the Mips volume
...
header in the ist sector. We now use the NetBSD label in preference
to the Mips Volume header.

Re-enable SR IE bit before calling syscall(). Matches Tohru's mips1 change.

There is no need to handle processor master interrupt mask SR_INT_IE
...
in syscall() anymore. By defition, processor was in SR_INT_IE turn
on prior to have syscall exception. MIPS1 assembler hook arranges
to enable the bit for its own. MIPS3 does the same effect by
turning off EXL bit.

- Reimplement MIPS1 cache size dectection logic taking advantage of the
...
fact the direct mapped cache makes address alias effect.
- Just turn on processor master interrupt mask IEc (SR_INT_IE) bit prior
to call syscall() kernel entry point. IEp is always 1 in this case
by defition.

Add a (commented out for now) VNODE_OP_NOINLINE options line, and mention
...
that it makes smaller and possibly slightly faster kernels.

Use VNODE_OP_NOINLINE - saves about 17k off the INSTALL kernel size.

IDT32364's Config register uses a different base for IC/DC (instruction
...
and data cache sizes). R4000 uses 2^(12+IC) and 2^(12+DC). IDT32364
uses 2^(9+IC) and 2^(9+DC).
abstract around the problem by making the base a parameter to the
MIPS3_CONFIG_CACHE_SIZE macro. we pass the base down from mips_vector_init
to mips3_vector_init and to mips3_ConfigCache (where it is used).
XXX: someone with an MIPS3_4100 should switch to this and get rid
of the ugly ifdefs in cpuregs.h

Use the complete ethernet address stored in nvram on mvme162/mvme167

instead of faking the first 5 nibbles a'la mvme147.
Apparently recent mvme16x boards have a new 5 nibble prefix...

Make sure pmap_collect() doesn't remove wired mappings. Per discussion
...
w/ Chuq Silvers. Fixes a panic when a program with wired pages that
has run for a long time when the system is under heavy memory load
exits (specific case was ntpd, reported by Simon Burge).

Add an align argument to uvm_map() and some callers of that

routine. Works similarly fto pmap_prefer(), but allows callers
to specify a minimum power-of-two alignment of the region.
How we ever got along without this for so long is beyond me.

Do not save t* registers in syscall stub as suggested by cgd. Saves
...
a whole 0.01us in lmbench lat_syscall null on our 250Mhz QED system.
$at is still saved just to be safe, although it looks like it does
not need to be. $v1 is used in syscall(), although I'm not sure why.

Introduce 'segbase' global variable to hold the pointer to current

process's segtab, retiring 'pcb_segtab' field from 'struct pcb'.
This would be another MULTIPROCESSOR unfriendly and the necessity
might be eliminated when the way to hold PTE is redesigned.
