Kevin Cernekee 081d835fa4 MIPS: Fix build errors in sc-mips.c
Seen with malta_defconfig on Linus' tree:

  CC      arch/mips/mm/sc-mips.o
arch/mips/mm/sc-mips.c: In function 'mips_sc_is_activated':
arch/mips/mm/sc-mips.c:77: error: 'config2' undeclared (first use in this function)
arch/mips/mm/sc-mips.c:77: error: (Each undeclared identifier is reported only once
arch/mips/mm/sc-mips.c:77: error: for each function it appears in.)
arch/mips/mm/sc-mips.c:81: error: 'tmp' undeclared (first use in this function)
make[2]: *** [arch/mips/mm/sc-mips.o] Error 1
make[1]: *** [arch/mips/mm] Error 2
make: *** [arch/mips] Error 2

[Ralf: Cosmetic changes to minimize the number of arguments passed to
mips_sc_is_activated]

Kevin Cernekee ea31a6b203 MIPS: Honor L2 bypass bit
On many of the newer MIPS32 cores, CP0 CONFIG2 bit 12 (L2B) indicates
that the L2 cache is disabled and therefore Linux should not attempt
to use it.

[Ralf: Moved the code added by Kevin's original patch into a separate
function that can easily be replaced for platforms that need more a
different probe.]

Atsushi Nemoto a2c2bc4b26 [MIPS] MIPS32/MIPS64 S-cache fix and cleanup
Use blast_scache_range, blast_inv_scache_range for mips32/mips64 scache
routine.  Also initialize waybit for MIPS32/MIPS64 S-cache.
