For HP Inc. mobile workstation with hybrid graphics support, dGPU can
directly output to external monitors; however, Nvidia and AMD's Linux
drivers aren't able to support this feature.
The OEM _OSI string "Linux-HPI-Hybrid-Graphics" is used by BIOS to
implement dGPU direct output to external monitors.
The form of the OEM _OSI strings is defined by each OEMs and is
discussed in Documentation/acpi/osi.txt.

Some ThinkPad systems have a power-saving feature that turns off HDMI
audio device in Windows, but NVidia Linux driver does not support this
feature. As a result, HDMI audio will not work on Linux.
A BIOS workaround is added with an OEM_OSI string
"Linux-Lenovo-NV-HDMI-Audio" to power on NVidia HDMI audio when booting.
The form of the OEM _OSI strings is defined by each OEMs and is
discussed in Documentation/acpi/osi.txt.

A number of Dell systems require an OEM _OSI string "Linux-Dell-Video"
as a BIOS workaround to disable RTD3 which causes systems hangs when
NVidia graphics cards are installed. The affected Dell systems are
with system IDs: 0818, 0819, 0820, 0850, 0851, 086F, 0870, 0885 and
0886.
The form of the OEM _OSI strings is defined by each OEMs and is
discussed in Documentation/acpi/osi.txt.

We're about to amend ACPI bus scan with DMI checks whether we're running
on a Mac to support Apple device properties in AML. The DMI checks are
performed for every single device, adding overhead for everything x86
that isn't Apple, which is the majority. Rafael and Andy therefore
request to perform the DMI match only once and cache the result.
Outside of ACPI various other Apple DMI checks exist and it seems
reasonable to use the cached value there as well. Rafael, Andy and
Darren suggest performing the DMI check in arch code and making it
available with a header in include/linux/platform_data/x86/.
To this end, add early_platform_quirks() to arch/x86/kernel/quirks.c
to perform the DMI check and invoke it from setup_arch(). Switch over
all existing Apple DMI checks, thereby fixing two deficiencies:
* They are now #defined to false on non-x86 arches and can thus be
optimized away if they're located in cross-arch code.
* Some of them only match "Apple Inc." but not "Apple Computer, Inc.",
which is used by BIOSes released between January 2006 (when the first
x86 Macs started shipping) and January 2007 (when the company name
changed upon introduction of the iPhone).

The function acpi_osi_dmi_linux() is local and does not need to be in
global scope, so make it static.
Cleans up sparse warning:
"symbol 'acpi_osi_dmi_linux' was not declared. Should it be static?"

_OSI handling code grows giant and it's time to move them into one file.
This patch collects all _OSI handling code into one single file.
So that we only have the following functions to be used externally:
early_acpi_osi_init(): Used by DMI detections;
acpi_osi_init(): Used to initialize OSI command line settings and install
Linux specific _OSI handler;
acpi_osi_setup(): The API that should be used by the external quirks.
acpi_osi_is_win8(): The API is used by the external drivers to determine
if BIOS supports Win8.
CONFIG_DMI is not useful as stub dmi_check_system() can make everything
stub because of strip.
No functional changes.
