From d5a7430ddcdb598261d70f7eb1bf450b5be52085 Mon Sep 17 00:00:00 2001 From: Mike Travis Date: Tue, 16 Oct 2007 01:24:05 -0700 Subject: Convert cpu_sibling_map to be a per cpu variable Convert cpu_sibling_map from a static array sized by NR_CPUS to a per_cpu variable. This saves sizeof(cpumask_t) * NR unused cpus. Access is mostly from startup and CPU HOTPLUG functions.
