Subject: [PATCH clocksource 0/2] Clocksource-watchdog classification and
 backoff

Hello!

This series adds comments classifying bogus measurements and adds capped
exponential backoff for messages that are likely caused by overly busy
systems.

1.	Add comments to classify bogus measurements.

2.	Exponential backoff for load-induced bogus watchdog reads.

						Thanx, Paul
