From d85a881d780cc7aaebe1b7aefcddbcb939acbe2d Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 23 Feb 2009 00:29:45 +0100 Subject: [PATCH] x86: remove various unused subarch hooks Impact: remove dead code Remove: - pre_setup_arch_hook() - mca_nmi_hook() If needed they can be added back via an x86_quirk handler.
