------------------------------------------------------
Subject: ntp: let update_persistent_clock() sleep
From: "Maciej W. Rozycki" <macro@xxxxxxxxxxxxxx>
This is a change that makes the 11-minute RTC update be run in the process
context. This is so that update_persistent_clock() can sleep, which may
be required for certain types of RTC hardware -- most notably I2C devices.
