From dc565b525d4b7091a3abb6616d210c8a896a11d7 Mon Sep 17 00:00:00 2001 From: "hawkes@sgi.com" Date: Mon, 10 Oct 2005 08:43:26 -0700 Subject: [IA64] wider use of for_each_cpu_mask() in arch/ia64 In arch/ia64 change the explicit use of for-loops and NR_CPUS into the general for_each_cpu() or for_each_online_cpu() constructs, as appropriate. This widens the scope of potential future optimizations of the general constructs, as well as takes advantage of the existing optimizations of first_cpu() and next_cpu().
