Subject: [ 087/127] powerpc/tm: Move TM abort cause codes to uapi

3.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Michael Neuling <mikey@...ling.org>

commit b75c100ef24894bd2c8b52e123bcc5f191c5d9fd upstream.

These cause codes are usable by userspace, so let's export to uapi.
