The series makes the arm_pmu driver use NMIs for the perf interrupt when NMIs are available on the platform (currently, only arm64 + GICv3). To make it easier to play with the patches, I've pushed a branch at [1]: $ git clone -b pmu-nmi-v5 git://linux-arm.org/linux-ae
For people who wanted to test the series, but couldn't because their firmware was setting SCR_EL3.FIQ, I pushed some patches [1] to fix that. Now pseudo-NMIs work on all GICv3 security + SCR_EL3.FIQ combinations.
