Subject: sh: constify prefetch pointers.
X-Git-Tag: v2.6.38-rc1~234^2~7
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c81fc389255d287dbfb17a70cd172663f962341a;p=karo-tx-linux.git

sh: constify prefetch pointers.

prefetch()/prefetchw() are supposed to take a const void * instead of a
straight void *, which the build recently started complaining about, fix
them up.
