Subject: [PATCH 05/28] ppc64: rename ppc64_paca_init to
 ppc64_paca_percpu_offset_init

ppc64_paca_init() function is specifically used to initialize percpu
data_offset for kernels older than v2.6.36. So, the name is slightly
misleading. Rename it to ppc64_paca_percpu_offset_init to reflect its
purpose.
