Honggang Li 6baa29b624 percpu: free percpu allocation info for uniprocessor system 
commit 3189eddbca upstream.

Currently, only SMP system free the percpu allocation info.
Uniprocessor system should free it too. For example, one x86 UML
virtual machine with 256MB memory, UML kernel wastes one page memory.
