Subject: s390/time: cast tv_nsec to u64 prior to shift in update_vsyscall
From: Martin Schwidefsky <schwidefsky@xxxxxxxxxx>
commit b6f4296279ab3ada554d993d12844272fd86b36a upstream.
Analog to git commit 28b92e09e25bdc0ae864b22eacf195a74f861389
first cast tk->wall_to_monotonic.tv_nsec to u64 before doing
the shift with tk->shift to avoid loosing relevant bits on a
32-bit kernel.
