[Qemu-devel] [PULL 12/18] qemu-timer: fix off-by-one

[Paolo Bonzini]

If the first timer is exactly at the current value of the clock, the
deadline is met and the timer should fire.  This fixes itself on the next
iteration of the loop without icount; with icount, however, execution
of instructions will stop exactly at the deadline and won't proceed.
