Switch the set/clear/change bitops to use the word-based exclusive operations, which are only present in a wider range of ARM architectures than the byte-based exclusive operations. Signed-off-by: Russell King <redacted>
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.
