X-Git-Tag: v2.6.34-rc1~285^2~122 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a6198a238baceae9d4e0ce3915f6d239c89b5c08;p=pandora-kernel.git sh: Guard against early IPIs in flush_cache_all(). flush_cache_all() gets called in to when we do some early ioremapping. Unfortunately on SDK7786 the interrupt controller itself requires ioremapping, leading to a bit of a chicken and egg scenario. For now, don't bother with IPI crosscalls if there aren't any other CPUs online. Signed-off-by: Paul Mundt --- Reading git-diff-tree failed
