mm: move get_user_pages()-related code to separate file
mm/memory.c is overloaded: over 4k lines. get_user_pages() code is pretty much self-contained let's move it to separate file. No other changes made. Signed-off-by: Kirill A. Shutemov <kirill.shutemov@linux.intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
