1d40cfcd34 Avoid SMP cacheflushes. This is a minor optimization of startup but 
will also avoid smp_call_function from doing stupid things when called
from a CPU that is not yet marked online.

569f75bd02 Use an irq_enable_hazard hazard barrier in unmask_mips_irq. This 
hasn't been an actual bug, so it's more a change to be 100% compliant
with the requirements of the architecture spec.  Similar fix to
mask_mips_irq where there was a slightly less theoretical chance of
getting hit.

a3701ca487 When CONFIG_PM is enabled, it uses the TOY_MATCH2 interrupt as the system 
timer tick. Prior to this patch, if IDE IRQ probing occured, then the
TOY_MATCH2 interrupt would be permanently disabled, and no system timer
tick occurs. This patch corrects this situation by correctly registering
the TOY_MATCH2 interrupt so that IDE IRQ probing doesn't have adverse
side effects.
