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. Arnd
