    Hi Sergei,

    Can you test the two patched attached instead please?

    I confirm that these two patches indeed fix the bug. I've applied them
    to the 6.1.128-1 kernel and used erlc (Erlang compiler) to reproduce
    the bug in QEMU. So far:

    1) Without the patches erlc emits efault (14) once in a 30-40 runs;
    2) With the patches erlc did not emit any efaults in a few thousand runs.

    So I think the patches are good.
    Cheers!
