Merge tag 'arm-perf-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux into next/drivers
Merge "arm-cci PMU updates for 4.1" from Will Deacon: CCI-400 PMU updates This series reworks some of the CCI-400 PMU code so that it can be used on both ARM and ARM64-based systems, without the need to boot in secure mode on the latter. This paves the way for CCI-500 support in future. * tag 'arm-perf-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux: arm-cci: Fix CCI PMU event validation arm-cci: Split the code for PMU vs driver support arm-cci: Get rid of secure transactions for PMU driver arm-cci: Abstract the CCI400 PMU specific definitions arm-cci: Rearrange code for splitting PMU vs driver code drivers: cci: reject groups spanning multiple HW PMUs + Linux 4.0-rc4 Signed-off-by: Olof Johansson <olof@lixom.net>
