I am not really sure if these patches should go through the ACPI or x86 tree.
I think they are more x86-ish related and earlier patches for tboot went through
tip.. Thoughts?
Theset two patches cleanup the ACPI code by removing the 'tboot_sleep'
function call within the ACPI call and instead use a function call.
The function call is set if Intel TXT is detected, otherwise we just skip over
and continue on in hwsleep.c.
Tested on AMD, Intel w/TXT and w/o TXT. Also compile tested on IA64 which has
some reference to tboot but does not use it.
The diff-stat:
arch/x86/kernel/tboot.c | 9 ++++++---
drivers/acpi/acpica/hwsleep.c | 10 +++++++---
drivers/acpi/osl.c | 24 ++++++++++++++++++++++++
include/acpi/acexcep.h | 1 +
include/linux/acpi.h | 10 ++++++++++
include/linux/tboot.h | 1 -
6 files changed, 48 insertions(+), 7 deletions(-)
The purpose of this cleanup is two-fold:
1). Cleanup the call a bit - that 'tboot_sleep' in ACPICA, which is suppose to
be
OS-agnostic code looks odd.
2). Piggy-back on the function call if running under Xen
[https://lkml.org/lkml/2011/12/16/447].
Those patches are still going through review, but the cleanup patches
can be submitted as standalone.
Thanks!
