Subject: mm: move vmalloc_init() declaration to mm/internal.h
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b671491199acd3609f87754d268f2f5cb10de18d;p=linux.git

mm: move vmalloc_init() declaration to mm/internal.h

vmalloc_init() is called only from mm_core_init(), there is no need to
declare it in include/linux/vmalloc.h

Move vmalloc_init() declaration to mm/internal.h
