Date: Thu, 31 Jan 2008 23:36:54 -0500 From: Len Brown <lenb@...nel.org> To: linux-pm@...ts.linux-foundation.org Cc: linux-acpi@...r.kernel.org, linux-kernel@...r.kernel.org, Johannes Berg <johannes@...solutions.net>, Pavel Machek <pavel@...e.cz>, "Rafael J. Wysocki" <rjw@...k.pl>, Len Brown <len.brown@...el.com> Subject: [PATCH 23/37] Suspend: Clean up Kconfig (V2) From: Johannes Berg <johannes@...solutions.net> This cleans up the suspend Kconfig and removes the need to declare centrally which architectures support suspend. All architectures that currently support suspend are modified accordingly.
