From 5dd3c9949a3e92ea7fd8c75d888031f7aff1f1d0 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Mon, 16 Mar 2009 14:12:42 +1030 Subject: cpumask: prepare for iterators to only go to nr_cpu_ids/nr_cpumask_bits.: ia64 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.
