When KVM_CAP_ADJUST_CLOCK is passed to KVM_CHECK_EXTENSION, it returns the
set of bits that KVM can return in struct kvm_clock_data's flag member.
The only flag defined now is KVM_CLOCK_TSC_STABLE. If set, the returned
value is the exact kvmclock value seen by all VCPUs at the instant
when KVM_GET_CLOCK was called. If clear, the returned value is simply
CLOCK_MONOTONIC plus a constant offset; the offset can be modified
with KVM_SET_CLOCK. KVM will try to make all VCPUs follow this clock,
but the exact value read by each VCPU could differ, because the host
TSC is not stable.
