Subject: [PATCH 22/37] Hibernation: Clean up Kconfig (V2)
Date: Thu, 31 Jan 2008 23:36:53 -0500 [thread overview]
Message-ID: <03f5cd73a5b5b30f6f3bcf8d68b3b79afb8cb880.1201840183.git.len.brown@intel.com> (raw)

In-Reply-To: <edae89f5d1eb1fbe1cab74333db5a8e29776900e.1201840183.git.len.brown@intel.com>
From: Johannes Berg <johannes@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.
