Subject: Revert "percpu: free percpu allocation info for uniprocessor system"
From: Guenter Roeck <linux@xxxxxxxxxxxx>
commit bb2e226b3bef596dd56be97df655d857b4603923 upstream.
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.
