2005-10-29Define and initialize kdb_lock using DEFINE_SPINLOCK.Ralf Baechle
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>
2005-10-29Make kgdb_wait static.Ralf Baechle
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>
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>
2005-10-29Philips PNX8550 support: MIPS32-like core with 2 Trimedias on it.Pete Popov

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>

2005-10-29Redo RM9000 workaround which along with other DSP ASE changes wasRalf Baechle
causing some headache for debuggers knowing about signal frames. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2005-10-29Enable a suitable ISA for the assembler around ll/sc so that codeMaciej W. Rozycki
builds even for processors that don't support the instructions. Plus minor formatting fixes. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2005-10-29For MIPS32/MIPS64 cp0.config.mt == 1 implies a standard (R4k-style)Maciej W. Rozycki
TLB, so no need to set it separately for each implementation. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2005-10-29Support the MIPS32 / MIPS64 DSP ASE.Ralf Baechle
Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2005-10-29Fix tasteless #ifdef mess in audit_arch(), minor cleanups.Ralf Baechle
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>
2005-10-29sys_nfsservctl() needs translation.Maciej W. Rozycki
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>
2005-10-29Cleanup decoding of MIPSxx config registers.Ralf Baechle
