Subject: [PATCH 12/14] RTC: Remove RTC UIP synchronization on Alpha
Date: Fri, 17 Mar 2006 17:30:37 -0600 [thread overview]
Message-ID: <13.132654658@selenic.com> (raw)
In-Reply-To: <2.132654658@selenic.com>
Remove RTC UIP synchronization on Alpha
The sync may still be needed for CPU clock calibration but we don't
sync in the regular case.
