Log message:
Introduce assembly macros for specific processor hazards: tlb update, status
register update, status register update causing a change to the interrupt
enable flag, and a few other arcane ones. <mips64/asm.h> will provide
(supposedly sane) defaults, and <machine/asm.h> may override these with
better tuned versions.
Use these macros instead of random strings of nop in the various .S files
requiring hazard workarounds.
