KVM: Depend on HIGH_RES_TIMERS

Liu, Jinsong · avikivity · commit 92b5265d38f6 · 2012-09-10T11:10:03.000+03:00
KVM lapic timer and tsc deadline timer based on hrtimer,
setting a leftmost node to rb tree and then do hrtimer reprogram.
If hrtimer not configured as high resolution, hrtimer_enqueue_reprogram
do nothing and then make kvm lapic timer and tsc deadline timer fail.
