Subject: um: fix global timer issue when using CONFIG_NO_HZ
From: Richard Weinberger <richard@xxxxxx>
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.
