The only known problem right now is that the pageattr.c changes seem to be miscompiled by the redhat compiler (but work with other compilers). But this sounds differently. I am still quite puzzled that this patch causes so many problems, if you look through it most changes are harmless cleanups or fixes only for very specific hardware configurations. But to double check could you just revert the pageattr.c hunk and see if that changes anything? -Andi -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
