2005-10-29__compute_return_epc() uses CFC1 instruction which might result in aRalf Baechle
coprocessor unusable exception since the process can lose its fpu context by preemption. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2005-10-29No point in checking cpu_has_tlb before we've computed the CPU options.Ralf Baechle
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. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2005-10-29When CONFIG_PM is enabled, it uses the TOY_MATCH2 interrupt as the systemPete Popov
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. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
