    Subject[107/289] um: fix global timer issue when using CONFIG_NO_HZ
    2.6.36-stable review patch.  If anyone has any objections, please let us know.

    ------------------

    From: Richard Weinberger <richard@nod.at>

    commit 482db6df1746c4fa7d64a2441d4cb2610249c679 upstream.

    This fixes a issue which was introduced by fe2cc53e ("uml: track and make
    up lost ticks").

    timeval_to_ns() returns long long and not int. Due to that UML's timer
    did not work properlt and caused timer freezes.
