From: David Woodhouse <[email protected]> get_kvmclock_base_ns() needs CLOCK_MONOTONIC_RAW + offs_boot. Compute this directly rather than reading offs_boot from the pvclock_gtod_data private copy. offs_boot only changes at suspend/resume so does not need to be atomically paired with the raw clock read.
