2014-02-06hp_accel: Add a new PnP ID HPQ6007 for new HP laptopsTakashi Iwai
commit b0ad4ff35d479a46a3b995a299db9aeb097acfce upstream. The DriveGuard chips on the new HP laptops are with a new PnP ID "HPQ6007". It should be compatible with older chips.

2013-06-07thinkpad-acpi: recognize latest V-Series using DMI_BIOS_VENDORManoj Iyer
commit a4f46bb9fa84642e356898ee44b670989622f8bb upstream. In the latest V-series bios DMI_PRODUCT_VERSION does not contain the string Lenovo or Thinkpad, but is set to the model number, this causes the thinkpad_acpi module to fail to load. Recognize laptop as Lenovo using DMI_BIOS_VENDOR instead, which is set to Lenovo.

commit 7783819920ca52fc582a2782f654fe6ed373f465 upstream. The error in lis3lv02_poweron() is harmless in the resume path, so we should ignore it.

2013-03-28asus-laptop: Do not call HWRS on initBen Hutchings
commit cb7da022450cdaaebd33078b6b32fb7dd2aaf6db upstream. Since commit 8871e99f89b7 ('asus-laptop: HRWS/HWRS typo'), module initialisation is very slow on the Asus UL30A. The HWRS method takes about 12 seconds to run, and subsequent initialisation also seems to be delayed. Since we don't really need the result, don't bother calling it on init. Those who are curious can still get the result through the 'infos' device attribute. Update the comment about HWRS in show_infos().

2013-02-14samsung-laptop: Disable on EFI hardwareMatt Fleming
commit e0094244e41c4d0c7ad69920681972fc45d8ce34 upstream. It has been reported that running this driver on some Samsung laptops with EFI can cause those machines to become bricked as detailed in the following report, https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557 There have also been reports of this driver causing Machine Check Exceptions on recent EFI-enabled Samsung laptops, https://bugzilla.kernel.org/show_bug.cgi?id=47121 So disable it if booting from EFI since this driver relies on grovelling around in the BIOS memory map which isn't going to work.

2013-02-14efi: Make 'efi_enabled' a function to query EFI facilitiesMatt Fleming
commit 83e68189745ad931c2afd45d8ee3303929233e7f upstream. Originally 'efi_enabled' indicated whether a kernel was booted from EFI firmware. Over time its semantics have changed, and it now indicates whether or not we are booted on an EFI machine with bit-native firmware, e.g. 64-bit kernel with 64-bit firmware. The immediate motivation for this patch is the bug report at, https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557 which details how running a platform driver on an EFI machine that is designed to run under BIOS can cause the machine to become bricked. Also, the following report, https://bugzilla.kernel.org/show_bug.cgi?id=47121 details how running said driver can also cause Machine Check Exceptions. Drivers need a new means of detecting whether they're running on an EFI machine, as sadly the expression, if (!efi_enabled) hasn't been a sufficient condition for quite some time. Users actually want to query 'efi_enabled' for different reasons - what they really want access to is the list of available EFI facilities. For instance, the x86 reboot code needs to know whether it can invoke the ResetSystem() function provided by the EFI runtime services, while the ACPI OSL code wants to know whether the EFI config tables were mapped successfully. There are also checks in some of the platform driver code to simply see if they're running on an EFI machine (which would make it a bad idea to do BIOS-y things). This patch is a prereq for the samsung-laptop fix patch.

Due to new supported hardware, of which the actual temperature limits of processor, harddisk and other components are unknown, it feels safer with lower fanon / fanoff settings. It won't change much for most people, already using acerhdf, as they use their own fanon/fanoff variable settings when loading the module. Furthermore seems like kernel and userspace tools have been improved to work more efficient and netbooks don't get so hot anymore.

2012-03-26asus-wmi: store backlight power status for AIO machineAceLan Kao
Due to some implementation reasons, ASUS ET2012 All-in-One machines can't report the correct backlight power status, it will always return 1. To track the backlight power status correctly, we have to store the status by ourselves. BTW, by the BIOS design, the backlight power will be turn on/off sequently, no matter what the value of the parameter will be. More over, the brightness adjustment command will turn on the backlight power. Those behaviors will make us fail to track the backlight power status. For example, While we are trying to turn on the backlight power, we will send out the brightness adjustment command and then trying to figure out if we have to turn on the backlight power, then send out the command. But, the real case is that, the backlight power turns on while sending the brightness adjustment command, and then we send out the command to turn on the backlight power, it actually will turn off the backlight power and the backlight power status we recorded becomes wrong. So, we have to seperate these two commands by a if statement.

2012-03-26asus-wmi: add scalar board brightness adj. supportAceLan Kao
Some ASUS ET2012E/I All-in-One machines that use a scalar board to control the brightness, and they only accept brightness up and down command. So, I introduced a get_scalar_command() function to pass the command to the scalar board through WMI. Besides, we have to store the brightness value locally, for we need the old value to know the brightness value is increasing or decreasing. BTW, since there is no way to retrieve the actual brightness(it would be a fixed value), and the max brightness value would be fixed to 1, so we have to keep passing the brightness up/down command when we reached the max brightness value or 0.

There's also a new initcall_debug feature from Arjan which will print out quirk timing information to help identify slow quirks for fixing or refinement (Yinghai sent in a few patches to do just that once the new debug code landed). Beyond that, I'm handing off PCI maintainership to Bjorn Helgaas. He's been a core PCI and Linux contributor for some time now, and has kindly volunteered to take over. I just don't feel I have the time for PCI review and work that it deserves lately (I've taken on some other projects), and haven't been as responsive lately as I'd like, so I approached Bjorn asking if he'd like to manage things. He's going to give it a try, and I'm confident he'll do at least as well as I have in keeping the tree managed, patches flowing, and keeping things stable."

2012-03-22toshiba_acpi: Support alternate hotkey interfacesSeth Forshee
There are two types of problems that prevent hotkeys from working on many of the machines supported by toshiba_acpi. The first of these is the lack of a functioning SCI for hotkey events. For these machines it is possible to filter the Fn keypresses from the keyboard and generate a notification by executing the ACPI NTFY method. The second problem is a lack of support for HCI_SYSTEM_EVENT, which is used for reading the hotkey scancodes. On these machines the scancodes can be read by executing the ACPI NTFY method. This patch fixes both problems by installing an i8042 filter when the NTFY method is present to generate notifications and by detecting which of INFO or HCI_SYSTEM_EVENT is supported for reading scancodes. If neither method of reading scancodes is supported, the hotkey input device is not registered.
