mm: fixup compilation error due to an asm write through a const pointer
This regression has been introduced in commit f56f821feb7b36223f309e0ec05986bb137ce418 Author: Daniel Vetter <daniel.vetter@ffwll.ch> 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.
