From 801e4062fda6496fe9bee3e6915a2aa108f974e5 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sat, 8 Dec 2007 02:12:39 +0100 Subject: [PATCH] Hibernation: Clean up Kconfig (V2) 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. Signed-off-by: Johannes Berg Acked-by: Paul Mackerras Cc: Pavel Machek Signed-off-by: Rafael J.
