1d74f6bc85 __compute_return_epc() uses CFC1 instruction which might result in a
coprocessor unusable exception since the process can lose its fpu
context by preemption.

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.

are now working for 80% of the ones I have tried. The other ones that do
not work all fail in the same way with the same messages. Once that bug
is tracked down, we should be in good shape. Task locking still needs
