From bb1f17b0372de93758653ca3454bc0df18dc2e5c Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Tue, 16 Jun 2009 15:31:18 -0700 Subject: mm: consolidate init_mm definition * create mm/init-mm.c, move init_mm there * remove INIT_MM, initialize init_mm with C99 initializer * unexport init_mm on all arches: init_mm is already unexported on x86. One strange place is some OMAP driver (drivers/video/omap/) which won't build modular, but it's already wants get_vm_area() export. Somebody should look there.
