Anton Ivanov 747b254ca2 um: Remove unnecessary faulted check in uaccess.c ... It is not necessary to check if a fault has occured or not after disabling pagefaults. kmap_atomic does that in all cases and we can disable it for 64 bit where kmap is not needed and a simple page_address would suffice. dd if=/dev/zero of=/dev/null bs=1M count=1M Before: 3.1GB/s. After: 3.5GB/s There is a noticeable difference for file disk read and write as well as less noticeable difference for network IO.
