X-Git-Tag: v2.6.17-rc6~11 X-Git-Url: https://git.kernelconcepts.de/?p=karo-tx-linux.git;a=commitdiff_plain;h=aa32374aaa2e516a9b0719477efae0782a62a79e [MIPS] SB1: Only pass1 FPUs are broken beyond recovery. The wrong revision number in the check was forcing a fallback to FPU emulation for all SB1 cores in 2.6.
