[PATCH 0/4] arm_arch_timer: VDSO preparation, code consolidation

This series contains the necessary changes to allow architected timer
access from user-space on 32-bit ARM.  This allows the VDSO to support
high resolution timestamps for clock_gettime and gettimeofday.  This
also merges substantially similar code from arm and arm64 into the
core arm_arch_timer driver.

These patches have been carried as part of the ARM VDSO patch set over
the last several months, but I am splitting them out here as I assume
they should go through the clocksource maintainer.

Nathan Lynch (4):
  clocksource: arm_arch_timer: change clocksource name if CP15
    unavailable
  clocksource: arm_arch_timer: enable counter access for 32-bit ARM
  ARM: arch_timer: remove unused functions
  arm64: arch_timer: remove unused functions
