Subject: [PATCH (2.6.25) 1/2] hibernation: clean up Kconfig
Date: Wed, 07 Nov 2007 14:57:59 +0100 [thread overview]
Message-ID: <20071107135848.417344000@sipsolutions.net> (raw)
In-Reply-To: 20071107135758.100171000@sipsolutions.net
This cleans up the hibernation Kconfig and removes the need to
declare centrally which architectures support hibernation. All
architectures that currently support hibernation are modified
accordingly.
