Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2005-10-29Avoid SMP cacheflushes. This is a minor optimization of startup butRalf Baechle
will also avoid smp_call_function from doing stupid things when called from a CPU that is not yet marked online. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2005-10-29Use an irq_enable_hazard hazard barrier in unmask_mips_irq. ThisRalf Baechle
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. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2005-10-29__compute_return_epc() uses CFC1 instruction which might result in aRalf Baechle

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
