2005-10-29Now that a struct is the only member left in structRalf Baechle
mips_fpu_emulator_stats cleanup that unnecessary nesting of structs. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2005-10-29Get rid of the eir struct mips_fpu_emulator_private member. It'sRalf Baechle
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. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
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>
