Merge branch 'timecounter-next'
Richard Cochran says: ==================== Fixing the "Time Counter fixes and improvements" For this series I had only tested the build with ARCH=x86 and arm, but others like sparc64, microblaze, powerpc, and s390 will fail because they somehow don't indirectly include clocksource.h for the drivers in question. This series fixes the build issues reported by: kbuild test robot <fengguang.wu@intel.com> ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
