Subject: [PATCH] Revert "percpu: free percpu allocation info for uniprocessor system"
Date: Sun, 21 Sep 2014 15:04:53 -0700	[thread overview]
Message-ID: <1411337093-683-1-git-send-email-linux@roeck-us.net> (raw)

This reverts commit 3189eddbcafc ("percpu: free percpu allocation info for
uniprocessor system").

The commit causes a hang with a crisv32 image. This may be an architecture
problem, but at least for now the revert is necessary to be able to boot a
crisv32 image.

Fixes: 3189eddbcafc ("percpu: free percpu allocation info for uniprocessor system")
