Ah, yes, OK. I suppose it's possible that __GFP_HIGHMEM was set. do_huge_pmd_anonymous_page ->pte_alloc_one ->alloc_pages(__userpte_alloc_gfp==__GFP_HIGHMEM) but I haven't traced that through and that's 32-bit. But anyway - Luke, please attach your .config to https://bugzilla.kernel.org/show_bug.cgi?id=87891? _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
