Disable cpu_has_mmips for everything but SEAD3 and MALTA. Most of these platforms are from before the micromips introduction, so they are very unlikely to implement it. Reduces an -Os compiled, uncompressed kernel image by 8KiB for BCM63XX. Signed-off-by: Jonas Gorski <jogo@xxxxxxxxxxx> --- Position chosen is based on asm/cpu-features.h. Missing hardware and/or data sheets for most platforms I obviously couldn't verify its non-existence, so maintainer acks are appreciated. arch/mips/include/asm/mach-ath79/cpu-feature-overrides.h | 1 +
