Btw,

while you're at it, this is what I get on 32-bit defconfig build:

arch/x86/kernel/cpu/perf_event_intel_uncore.c: In function ‘uncore_pmu_hrtimer’:
arch/x86/kernel/cpu/perf_event_intel_uncore.c:1892:43: warning: integer overflow in expression
arch/x86/kernel/cpu/perf_event_intel_uncore.c: In function ‘uncore_pmu_start_hrtimer’:
arch/x86/kernel/cpu/perf_event_intel_uncore.c:1899:16: warning: integer overflow in expression

due to UNCORE_PMU_HRTIMER_INTERVAL overflowing 32 bit.

.config is attached.

HTH.
