SubjectNot able to use HIGH_RES_TIMERS on ARM
From
Hi John, refering to you patch:

ARM: remove 'select GENERIC_TIME'
GENERIC_TIME is now enabled by default, so 'select GENERIC_TIME' is
redundant. Remove them.

The following config's are not selectable:
config NO_HZ, config HIGH_RES_TIMERS, config IRQSOFF_TRACER, config
PREEMPT_TRACER

As far as I know, ARM now uses GENERIC_TIME via the arch_getoffset()
infrastructure, i.e ARCH_USES_GETTIMEOFFSET=y
