Peter Anvin" <hpa@...or.com>, Ingo Molnar <mingo@...e.hu>, Thomas Gleixner <tglx@...utronix.de> CC: linux-kernel@...r.kernel.org Subject: x86: compile pat debugfs interface only if CONFIG_X86_PAT is set Signed-off-by: Andreas Herrmann <andreas.herrmann3@....com> --- arch/x86/mm/pat.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) Recently I've run a kernel w/o PAT support and wondered why there was a file "x86/pat_memtype_list" in debugfs. Of course it's empty if PAT is disabled ... so just get rid of this interface if PAT is disabled. Please apply.
