From 2c6e6db41f01b6b4eb98809350827c9678996698 Mon Sep 17 00:00:00 2001 From: "holt@sgi.com" Date: Thu, 3 Apr 2008 15:17:13 -0500 Subject: [IA64] Minimize per_cpu reservations. This attached patch significantly shrinks boot memory allocation on ia64. It does this by not allocating per_cpu areas for cpus that can never exist. In the case where acpi does not have any numa node description of the cpus, I defaulted to assigning the first 32 round-robin on the known nodes.. For the !CONFIG_ACPI I used for_each_possible_cpu().
