Subject: [PATCH] percpu: factor out pcpu_addr_in_first/reserved_chunk() and
 update per_cpu_ptr_to_phys()

Factor out pcpu_addr_in_first/reserved_chunk() from
pcpu_chunk_addr_search() and use it to update per_cpu_ptr_to_phys()
such that it handles first chunk differently from the rest.

This patch doesn't cause any functional change and is to prepare for
percpu nommu support.
