Subject: [PATCH 01/10] -mm: clocksource: increase initcall priority
Date: Fri, 06 Oct 2006 11:54:40 -0700 [thread overview]
Message-ID: <20061006185456.261581000@mvista.com> (raw)
In-Reply-To: 20061006185439.667702000@mvista.com
[-- Attachment #1: clocksource_init_call.patch --]
[-- Type: text/plain, Size: 4627 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.
