H A D | usercopy.c | 8e1f74ea Wed Sep 07 11:54:34 CDT 2016 Kees Cook <keescook@chromium.org> usercopy: remove page-spanning test for now
A custom allocator without __GFP_COMP that copies to userspace has been found in vmw_execbuf_process[1], so this disables the page-span checker by placing it behind a CONFIG for future work where such things can be tracked down later.
