I can still restructure this and pull the INTEGRATOR_CM1136JFS
removal a little earlier. At the moment, this is part of the
patch to remove CPU_ARM1136R0, which I had planned to submit
once the arch/arm/mach-*/ platform removal patches are done:
https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc.git/commit/?id=a8cfcc5533e33a
I could turn the mach-versatile/Kconfig change into a separate
(trivial) patch and add it to the platform series to avoid
churn here. The armv6 cmpxchg() code would still exist
in 7.4 then, but be unreachable.
