[MIPS] Fix WARNING: at kernel/smp.c:290
trap_init issues flush_icache_range(), which uses ipi functions to get icache flushing done on all cpus. But this is done before interrupts are enabled and caused WARN_ON messages. This changeset introduces a new local_flush_icache_range() and uses it before interrupts (and additional CPUs) are enabled to avoid this problem.
