Subject: [PATCH 01/10] -mm clocksource: increase initcall priority
Date: Thu, 03 Aug 2006 20:24:15 -0700 [thread overview]
Message-ID: <20060804032510.405094000@mvista.com> (raw)
In-Reply-To: 20060804032414.304636000@mvista.com
[-- Attachment #1: clocksource_init_call.patch --]
[-- Type: text/plain, Size: 4626 bytes --]
Since it's likely that this interface would get used during bootup
I moved all the clocksource registration into the postcore initcall.
This also eliminated some clocksource shuffling during bootup.
