Subject: cpumask: remove unused cpu_mask_all
X-Git-Tag: v2.6.32-rc1~144^2~31
X-Git-Url: http://ftp.safe.ca/?p=safe%2Fjmp%2Flinux-2.6;a=commitdiff_plain;h=72d78d05cbaa69f2a32f5f9d65a4551ba0da571f

cpumask: remove unused cpu_mask_all

It's only defined for NR_CPUS > BITS_PER_LONG; cpu_all_mask is always
defined (and const).
