Subject: linux-next: manual merge of the arm-perf tree with Linus' and teh
arm-current trees
Hi Will,
Today's linux-next merge of the arm-perf tree got a conflict in
arch/arm/kernel/perf_event_cpu.c between commit 338d9dd3e2ae ("ARM:
8351/1: perf: don't warn about missing interrupt-affinity property for
PPIs") from Linus' tree and 8d2812849acb ("ARM: 8357/1: perf: fix
memory leak when probing PMU PPIs") from the arm-current tree and
commit 64d0d3943e14 ("arm: perf: make of_pmu_irq_cfg take arm_pmu")
from the arm-perf tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
