Commit 14bd8c08, that replaced Loongson2-specific ifdefs with cpu tests, inverted the CPU test in local_r4k_flush_icache_range. Loongson2 won't boot up using the generic icache flush code. Presumably other CPUs might face other problems when presented with Loongson2-specific icache flush code too. This patch enabled my Yeeloong to boot up successfully a 3.13-rc kernel for the first time, after a long git bisect session.
