Revision 8e1f74ea02cf4562404c48c6882214821552c13f authored by Kees Cook on 07 September 2016, 16:54:34 UTC, committed by Kees Cook on 07 September 2016, 18:33:26 UTC
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.
