Will,
In next-20120523, the following two commits of yours collided:
d33c88c ARM: 7315/1: perf: add support for the Cortex-A7 PMU
(adds new entry to perf_event_v7.c)
b3426c5 ARM: perf: remove arm_perf_pmu_ids global enumeration
(removes a field from entries in perf_event_v7.c)
This causes:
> In file included from arch/arm/kernel/perf_event.c:610:0:
> arch/arm/kernel/perf_event_v7.c: In function 'armv7_a7_pmu_init':
> arch/arm/kernel/perf_event_v7.c:1294:10: error: 'struct arm_pmu' has no member named 'id'
> arch/arm/kernel/perf_event_v7.c:1294:17: error: 'ARM_PERF_PMU_ID_CA7' undeclared (first use in this function)
The following fixes the compilation error, although I put no thought
into whether it actually works at run-time:
