MIPS: octeon: Remove cpu_has_saa (ece51529) · Commits · 戴 / test

The cpu_has_saa feature macro was added along with Cavium Octeon CPU support back in commit ("MIPS: Add Cavium OCTEON processor support files to arch/mips/cavium-octeon.") but has never been used. Remove the dead code. Signed-off-by:
