And it looks like this seeding is where much of the remaining backwards
deltas are coming from: While on local_time_calibration()'s slow path
we use the platform time as reference (and hence the seeding is fine),
on the fast path we don't, and hence using the platform time in
init_percpu_time() to initialize local stime introduces a discontinuity.
