Date: Tue, 17 Sep 2013 14:48:13 +0800 From: "Yan, Zheng" <zheng.z.yan@...el.com> To: peterz@...radead.org Cc: eranian@...gle.com, mingo@...nel.org, linux-kernel@...r.kernel.org, "Yan, Zheng" <zheng.z.yan@...el.com> Subject: [PATCH] perf/x86/intel/uncore: don't use smp_processor_id() in validate_group() From: "Yan, Zheng" <zheng.z.yan@...el.com> uncore_validate_group() can't call smp_processor_id() because it is in preemptible context. Pass NUMA_NO_NODE to the allocator instead.
