Subject: x86: allow user to impress friends.
X-Git-Tag: v2.6.26-rc1~1154^2~369
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=904541e2f76bc3efe4cc9978b7adb3323ea8607e;p=pandora-kernel.git

x86: allow user to impress friends.

Impressing friends is a very important thing.
Do it in a separate function to make it even more
explicit, and ease integration.
