   Please also specify that commit's summary line in parens.

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.
