fded2e508a Optimize R3k TLB Load/Store/Modified handlers, by scheduling 
delay slots properly and avoiding an unnecessary jump to a jump.

d5b6f1db5d For MIPS32/MIPS64 cp0.config.mt == 1 implies a standard (R4k-style) 
TLB, so no need to set it separately for each implementation.

baee502ce2 Get rid of the eir struct mips_fpu_emulator_private member. It's 
never initialized been initialized anywhere, just saved to and
restored from signal frames so nonsense anyway.  As neat side effect
of being shared between all processors it was also abusable as a
nice covert channel between processes.

b382fe8483 No point in checking cpu_has_tlb before we've computed the CPU options. 
So for now we just unconditionally set the option - Linux wouldn't
work without a TLB anyway.
    
Setting MIPS_CPU_4KTLB was missing for Alchemy and Sandcraft, add that
back.

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.
