Subject: [v2.6.34-stable 76/77] x86: Get rid of asmregparm

From: Richard Weinberger <richard@....at>

                   -------------------
    This is a commit scheduled for the next v2.6.34 longterm release.
    http://git.kernel.org/?p=linux/kernel/git/paulg/longterm-queue-2.6.34.git
    If you see a problem with using this for longterm, please comment.
                   -------------------

commit 1b4ac2a935aaf194241a2f4165d6407ba9650e1a upstream.

As UML does no longer need asmregparm we can remove it.
