Subject: [PATCH 05/28] ppc64: rename ppc64_paca_init to
|
|
|
acf3ec |
ppc64_paca_percpu_offset_init
|
|
|
acf3ec |
|
|
|
acf3ec |
ppc64_paca_init() function is specifically used to initialize percpu
|
|
|
acf3ec |
data_offset for kernels older than v2.6.36. So, the name is slightly
|
|
|
acf3ec |
misleading. Rename it to ppc64_paca_percpu_offset_init to reflect its
|
|
|
acf3ec |
purpose.
