X-Git-Tag: v2.6.26-rc1~1146^2~3^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2c6e6db41f01b6b4eb98809350827c9678996698;p=pandora-kernel.git [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().
