Subject: [PATCH] Only allocate percpu data for possible CPUs
X-Git-Tag: v2.6.17-rc1~1004
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=63872f87a151413100678f110d1556026002809e;p=pandora-kernel.git

[PATCH] Only allocate percpu data for possible CPUs

percpu_data blindly allocates bootmem memory to store NR_CPUS instances of
cpudata, instead of allocating memory only for possible cpus.

This patch saves ram, allocating num_possible_cpus() (instead of NR_CPUS)
instances.
