Cover letter [patch v2 0/3] kvmclock: allow stable sched clock
kvmclock provides the behaviour sched_clock users expect. Mark it as stable allowing nohz_full in guests. See individual patches for more details.
v2: address comments from Paolo:
- set COUNTS_FROM_ZERO unconditionally (host).
- rely on KVM_FEATURE_CLOCKSOURCE_STABLE_BIT (guest).
