Subject: x86: move load_cr3 to a common place.
X-Git-Tag: v2.6.25-rc1~1143^2~545
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c72dcf83ff8585c95739abffa3be7c87ca63d66b;p=pandora-kernel.git

x86: move load_cr3 to a common place.

There are currently two definitions of load_cr3, that essentially do the
same thing. This patch moves them all to processor.h.
