Ralf Baechle 02416dcf5a Redo RM9000 workaround which along with other DSP ASE changes was
causing some headache for debuggers knowing about signal frames.

Maciej W. Rozycki aac8aa7717 Enable a suitable ISA for the assembler around ll/sc so that code
builds even for processors that don't support the instructions.
Plus minor formatting fixes.

Maciej W. Rozycki fded2e508a Optimize R3k TLB Load/Store/Modified handlers, by scheduling
delay slots properly and avoiding an unnecessary jump to a jump.

Maciej W. Rozycki 15b6e09b66 dec_esp: Use physical addresses
These should really be addresses obtained with ioremap() or some
bus-specific backend, but for now...

no further action wanted.

Maciej W. Rozycki d5b6f1db5d For MIPS32/MIPS64 cp0.config.mt == 1 implies a standard (R4k-style)
TLB, so no need to set it separately for each implementation.

Ralf Baechle baee502ce2 Get rid of the eir struct mips_fpu_emulator_private member. It's
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.

Ralf Baechle 1d74f6bc85 __compute_return_epc() uses CFC1 instruction which might result in a
coprocessor unusable exception since the process can lose its fpu
context by preemption.

Ralf Baechle b382fe8483 No point in checking cpu_has_tlb before we've computed the CPU options.
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.
