Ok, as far as stable goes, this patch wouldn't apply cleanly going all the way back to 0d651e4e65e9 As-is, it would need to go after 220069945b29 "clocksource: arch_timer: Add support for memory mapped timers" and there would need to be another, simpler, version that went between those two commits.
