Subject: x86: move and enhance debug printk for nr_cpu_ids etc.
X-Git-Tag: v2.6.29-rc1~538^2~21^2~13
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=a1681965011916c2f1f0f1f87e70784f5d5d5be5;p=linux-2.6-omap-h63xx.git

x86: move and enhance debug printk for nr_cpu_ids etc.

Impact: cleanup, better debugging

This has proven useful in debugging, *before* we try to use
for_each_possible_cpu().  It also now shows nr_cpumask_bits.
