Settings ack for inclusion in 5.1.z stream.

Reassigning to Chris at his request.

Updating to urgent to get z-stream ack.

This needs to be fixed in the kernel rpm.

__clean_user needs to be added to the ppc kernel whitelist (as it is already on
the x86_64 & x86 whitelists).  We're currently working around the issue in 5.1,
but it should be in 5.2 if at all possible.

The actual symbol is __clear_user (not __clean_user), I've updated the bug subject.

in kernel-2.6.18-73.el5
You can download this test kernel from http://people.redhat.com/dzickus/el5

verified __clear_user is being exported on ppc and I could install the
2.6.18-88.el5 kernel rpm without issues.
