Subject[PATCH 3.10 23/24] powerpc: 32 bit getcpu VDSO function uses 64 bit instructions
Date
3.10-stable review patch.  If anyone has any objections, please let me know.

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

From: Anton Blanchard <anton@samba.org>

commit 152d44a853e42952f6c8a504fb1f8eefd21fd5fd upstream.

I used some 64 bit instructions when adding the 32 bit getcpu VDSO
function. Fix it.

Fixes: 18ad51dd342a ("powerpc: Add VDSO version of getcpu")
