Hi,

These fixes are more band-aids than anything else but they at least
improve on the original situation where running a zephyr build with:

  -icount shift=6,align=off,sleep=off

would lock the monitor hard as time rushed into the future. With these
patches time still runs to the future pretty fast as Zephyr spends
most of it's time in WFI waiting for input with a CVAL far in the
future. This does does raise the question of what sleep=off is even
for?

Alex Bennée (2):
  qemu-timer: gracefully handle the end of time
  target/arm: only set the nexttick timer if !ISTATUS
