As only one person replied to this patch with test information, I'm
not happy to push this into -rc, and hence that prevents it going into
-stable too.  That means omap2plus_defconfig .38 mainline kernels
(including -stable) will remain potentially dangerous when run on
SMP capable hardware.

Therefore, I see no alternative at the moment but to purposely cause
builds which cover ARMv6, and ARMv6K or ARMv7 CPUs to save people from
data corruption.

Please get your tested-by's to me for at least the first three patches
of this series ASAP.
