Kees Cook f9ae153c05 UPSTREAM: 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.
