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
