From ec7c14bde80a11e325f26b339b8570a929e87223 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Mon, 16 Mar 2009 14:40:24 +1030 Subject: cpumask: prepare for iterators to only go to nr_cpu_ids/nr_cpumask_bits.: sparc Impact: cleanup, futureproof In fact, all cpumask ops will only be valid (in general) for bit numbers < nr_cpu_ids. So use that instead of NR_CPUS in various places. This is always safe: no cpu number can be >= nr_cpu_ids, and nr_cpu_ids is initialized to NR_CPUS at boot.
