From: Arjan van de Ven Date: Mon, 18 Feb 2008 17:54:33 +0000 (-0800) Subject: x86: fix WARN_ON() message: teach page_is_ram() about the special 4Kb bios data page X-Git-Tag: v2.6.25-rc3~109^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d8a9e6a51ec58486f850e3606e3fcb86b5b7da41;p=pandora-kernel.git x86: fix WARN_ON() message: teach page_is_ram() about the special 4Kb bios data page This patch teaches page_is_ram() about the fact that the first 4Kb of memory are special on x86, even though the E820 table normally doesn't exclude it. This fixes the WARN_ON() reported by Laurent Riffard who was also very helpful in diagnosing the issue. [ mingo@elte.hu: we are working on doing this properly in the e820 space, but for 2.6.25 this is the better fix. ] Signed-off-by: Arjan van de Ven Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner --- Reading git-diff-tree failed
