  - mips: select CONFIG_WEAK_REORDERING_BEYOND_LLSC from CONFIG_EYEQ On I6500 CPU cores, lld and scd give no     ordering guarantees (same as all other instructions). To respect the assumption that arch_cmpxchg() is     fully ordered, we must inject sync instructions above and below our lld/scd loops using the already in     place WEAK_REORDERING_BEYOND_LLSC infrastructure.
