Luis Chamberlain 4fa7252338 include/linux/cache.h: expand documentation over __read_mostly
__read_mostly can easily be misused by folks, its not meant for just
read-only data.  There are performance reasons for using it, but we also
don't provide any guidance about its use.  Provide a bit more guidance
over its use.
