I ran these patches through my autobuilder, and while most builds didn't
seem to be a problem, the randconfigs found errors:

The root cause is that the kernel being built is supposed to support
both ARMv7 and ARMv6K CPUs. However, "rbit" is only available on
ARMv6T2 (thumb2) and ARMv7, and not plain ARMv6 or ARMv6K CPUs.
