From: Pavel Machek Date: Sat, 10 Sep 2005 07:27:19 +0000 (-0700) Subject: [PATCH] remove ACPI S4bios support X-Git-Tag: v2.6.14-rc1~160 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=b01d8684e9e5b04270970c97df856d47668267e3;p=linux-2.6-omap-h63xx.git [PATCH] remove ACPI S4bios support Remove S4BIOS support. It is pretty useless, and only ever worked for _me_ once. (I do not think anyone else ever tried it). It was in feature-removal for a long time, and it should have been removed before.
