Subject: [PATCH v2 05/14] mm/page_alloc: rename page_alloc_init() to page_alloc_init_cpuhp()

From: "Mike Rapoport (IBM)" <rppt@...nel.org>

The page_alloc_init() name is really misleading because all this
function does is sets up CPU hotplug callbacks for the page allocator.

Rename it to page_alloc_init_cpuhp() so that name will reflect what the
function does.
