Atsushi Nemoto 1acf1ca7e9 [MIPS] Fix modpost warning: Rename op_model_xxx to op_model_xxx_ops.
The modpost uses a whitelist for commonly used suffix on checking the
section mismatch.  Adding "_ops" suffix to op_modex_xxx get rid of
this modpost warning.
    
WARNING: arch/mips/oprofile/oprofile.o - Section mismatch: reference to .init.text: from .data after 'op_model_mipsxx' (at offset 0x528)

Chris Dearman c620953c32 [MIPS] Fix detection and handling of the 74K processor.
Nothing exciting; Linux just didn't know it yet so this is most adding
a value to a case statement.

Ralf Baechle 54176736f7 More oprofile bits for MIPS32-style performance counters. The code to
bolt this into the actual hardware interrupt is yet missing from this
commit.
