From a06f916b7a9b57447ceb875eb0a89f1a66b31bca Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 20 Oct 2011 22:04:18 +0100 Subject: ARM: smp: fix clipping of number of CPUs Rather than clipping the number of CPUs using the compile-time NR_CPUS constant, use the runtime nr_cpu_ids value instead. This allows the nr_cpus command line option to work as expected.
