* Detect 4KSD and treat it like 4KSc.Ralf Baechle2005-10-29
| | | | Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* Define and initialize kdb_lock using DEFINE_SPINLOCK.Ralf Baechle2005-10-29
| | | | | | | | | Convert kgdb_cpulock into a raw_spinlock_t. SPIN_LOCK_UNLOCKED is deprecated and it's replacement DEFINE_SPINLOCK is not suitable for arrays of spinlocks. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* Make kgdb_wait static.Ralf Baechle2005-10-29
| | | | | | | Nothing outside gdb-stub.c uses kgdb_wait, so change it's definition to static. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

| | | | Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* Avoid SMP cacheflushes. This is a minor optimization of startup butRalf Baechle2005-10-29
| | | | | | | 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>

* Use an irq_enable_hazard hazard barrier in unmask_mips_irq. ThisRalf Baechle2005-10-29
| | | | | | | | | 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>

* No point in checking cpu_has_tlb before we've computed the CPU options.Ralf Baechle2005-10-29
| | | | | | | | | | 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>
