From 9923777dff4543050fdf938cf6b19f6d4376b7c5 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Sat, 14 Apr 2012 18:03:10 +0200 Subject: mm: fixup compilation error due to an asm write through a const pointer This regression has been introduced in commit f56f821feb7b36223f309e0ec05986bb137ce418 Author: Daniel Vetter Date: Sun Mar 25 19:47:41 2012 +0200 mm: extend prefault helpers to fault in more than PAGE_SIZE I have failed to notice this because x86 asm seems to happily compile things as-is.
