From f6325e30ebd6fc870315b017a5d4a6ab15bf790b Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 17 Dec 2009 11:43:08 -0600 Subject: [PATCH] cpumask: use cpu_online in kernel/perf_event.c Also, we want to check against nr_cpu_ids, not num_possible_cpus(). The latter works, but the correct bounds check is < nr_cpu_ids.
