It's going to break again with things like ADI which encode protection keys in the high bits of the 64-bit virtual address. Reallly, it would be nice if these tags were instead encoded in the low bits of suitably aligned memory allocations but I am sure it's to late to do that now. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
