Subject: [RFC PATCH 8/8] Revert "percpu: free percpu allocation info for uniprocessor system"

This reverts commit 3189eddbcafcc4d827f7f19facbeddec4424eba8.

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.
