Subject: For MIPS32/MIPS64 cp0.config.mt == 1 implies a standard (R4k-style)
X-Git-Tag: v2.6.15-rc1~731^2~1^2~199
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d5b6f1db5d5a7ba3f2271e5018db7c8c5c4eeea1;p=platform%2Fkernel%2Flinux-3.10.git

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