ACPI / init: Make it possible to override _REV

The platform firmware on some systems expects Linux to return "5" as
the supported ACPI revision which makes it expose system configuration
information in a special way.

For example, based on what ACPI exports as the supported revision,
Dell XPS 13 (2015) configures its audio device to either work in HDA
mode or in I2S mode, where the former is supposed to be used on Linux
until the latter is fully supported (in the kernel as well as in user
space).

Since ACPI 6 mandates that _REV should return "2" if ACPI 2 or later
is supported by the OS, a subsequent change will make that happen, so
make it possible to override that on systems where "5" is expected to
be returned for Linux to work correctly one them (such as the Dell
machine mentioned above).

ACPI: move models with win8 brightness problems from win8 blacklist to use_native_backlight

When the windows8 related backlight problems became evident, 2 approaches
were follow in parallel, one was to stop claiming to be windows 8 / 2012,
the other was to tell acpi_video to stop registering a backlight driver.

I've read all the threads and it seems that which approach ended up being
applied to which model laptop was never really a concious decision (AFAIK):

https://bugzilla.kernel.org/show_bug.cgi?id=51231
https://bugzilla.kernel.org/show_bug.cgi?id=60682

So lets move all the models which are only on the win8 blacklist because of
brightness issues to the use_native_backlight list, which is the smaller
hammer to use to solve the backlight issues.

Making this change is esp. attractive now that 3.16 has
video.use_native_brightness=1 by default. If that new default does not get
reverted because of regressions, then we can drop all the models
with a use_native_backlight quirk, greatly reducing the number of models we've
a quirk for.

ACPI / video: Add systems that should favour native backlight interface

Some system's ACPI video backlight control interface is broken and the
native backlight control interface should be used by default. This patch
sets the use_native_backlight parameter to true for those systems so
that video backlight control interface will not be created. For detailed
models that are added here, reference the following list.

Note that the user specified kernel cmdline option will always have the
highest priority, i.e. if use_native_backlight=0 is specified and the
system is in the DMI table, the video module will not skip registering
backlight interface for it.

ACPI: Clean up inclusions of ACPI header files

Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and
<acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h>
inclusions and remove some inclusions of those files that aren't
necessary.

First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>
should not be included directly from any files that are built for
CONFIG_ACPI unset, because that generally leads to build warnings about
undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set,
<linux/acpi.h> includes those files and for CONFIG_ACPI unset it
provides stub ACPI symbols to be used in that case.

Second, there are ordering dependencies between those files that always
have to be met. Namely, it is required that <acpi/acpi_bus.h> be included
prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the
latter depends on are always there. And <acpi/acpi.h> which provides
basic ACPICA type declarations should always be included prior to any other
ACPI headers in CONFIG_ACPI builds. That also is taken care of including
<linux/acpi.h> as appropriate.

ACPI: delete CONFIG_ACPI_BLACKLIST_YEAR

About 10 years ago, this option was created to help
distros enable ACPI and not get distracted by ACPI
BIOS issues in machines which were deemed old
at that time, eg 1999 and earlier.

After a couple of years, the high volume distros
stopped bothering to set this option, and instead
simply ran in ACPI mode on all systems with an
ACPI BIOS -- regardless of BIOS DMI year.

Recently there have been some ACPI-enabled systems
with no DMI, mandating that CONFIG_ACPI_BLACKLIST_YEAR=0.

So it seems vanishingly unlikely that this option
is helping anybody run a 2013 kernel on a 1998 system,
and now more systems mandate this option be disabled,
so we simplify by deleting it entirely.

ACPI: blacklist win8 OSI for buggy laptops

Since v3.7 the acpi backlight driver doesn't work correctly in several
machines because ACPI code has different code for Windows 8, and the
rest.

The commit ea45ea7 (in v3.11-rc2) tried to fix this problem by using the
intel backlight driver, however it introduced several other issues in
different machines.

This patch fixes both regressions by blacklisting the win8 OSI, so we
are back to v3.6 behavior, and it should remain that way until the intel
backlight driver is fixed.

Since v3.7, users have been forced to fix the initial regression by
modifying the boot arguments (acpi_osi="!Windows 2012").

Once the Intel backlight driver works correctly for all machines, this
blacklist can be removed and that driver can be used instead.

ACPI: blacklist win8 OSI for ASUS Zenbook Prime UX31A

Since v3.7 the ACPI backlight driver doesn't work at all on this
machine, because presumably the backlight AML code in the ACPI
tables contains a code path that triggers when the OS identifies
itself as compatible with Windows 8 (which the kernel started to
do in 3.7). That code path is never used by Windows and on this
particular machine it turns out to be unusable at all.

Work around this problem by blacklisting the win8 OSI, so we are back
to v3.6 behavior (that is, we don't tell the BIOS that we are
compatible with Windows 8).

Since v3.7, users have been forced to work around the initial
regression by modifying the boot arguments [1].

ACPI: disable _OSI(Windows 2009) on Asus K50IJ

Fix a win7 compability issue on Asus K50IJ.

Here is the _BCM method of this laptop:
Method (_BCM, 1, NotSerialized)
{
If (LGreaterEqual (OSFG, OSVT))
{
If (LNotEqual (OSFG, OSW7))
{
Store (One, BCMD)
Store (GCBL (Arg0), Local0)
Subtract (0x0F, Local0, LBTN)
^^^SBRG.EC0.STBR ()
...
}
Else
{
DBGR (0x0B, Zero, Zero, Arg0)
Store (Arg0, LBTN)
^^^SBRG.EC0.STBR ()
...
}
}
}
LBTN is used to store the index of the brightness level in the _BCL.
GCBL is a method that convert the percentage value to the index value.
If _OSI(Windows 2009) is not disabled, LBTN is stored a percentage
value which is surely beyond the end of _BCL package.

dmi: extend dmi_get_year() to dmi_get_date()

There are cases where full date information is required instead of
just the year. Add month and day parsing to dmi_get_year() and rename
it to dmi_get_date().

As the original function only required '/' followed by any number of
parseable characters at the end of the string, keep that behavior to
avoid upsetting existing users.

The new function takes dates of format [mm[/dd]]/yy[yy]. Year, month
and date are checked to be in the ranges of [1-9999], [1-12] and
[1-31] respectively and any invalid or out-of-range component is
returned as zero.

The dummy implementation is updated accordingly but the return value
is updated to indicate field not found which is consistent with how
other dummy functions behave.

ACPI: Move definition of PREFIX from acpi_bus.h to internal..h

Linux/ACPI core files using internal.h all PREFIX "ACPI: ",
however, not all ACPI drivers use/want it -- and they
should not have to #undef PREFIX to define their own.

Add GPL commment to internal.h while we are there.

This does not change any actual console output,

ACPI: DMI blacklist to reduce console warnings on OSI(Linux) systems.

This DMI blacklist reduces the console messages
on systems which have a BIOS that invokes OSI(Linux).

As the DMI blacklist already knows about these systems,
the request for DMI info itself is disabled.

Further, if OSI(Linux) has already been determined
to have no beneift, we disable the console message
requesting acpi_osi=Linux test results.

ACPI: make _OSI(Linux) console messages smarter

If BIOS invokes _OSI(Linux), the kernel response
depends on what the ACPI DMI list knows about the system,
and that is reflectd in dmesg:

1) System unknown to DMI:

ACPI: BIOS _OSI(Linux) query ignored
ACPI: DMI System Vendor: LENOVO
ACPI: DMI Product Name: 7661W1P
ACPI: DMI Product Version: ThinkPad T61
ACPI: DMI Board Name: 7661W1P
ACPI: DMI BIOS Vendor: LENOVO
ACPI: DMI BIOS Date: 10/18/2007
ACPI: Please send DMI info above to linux-acpi@vger.kernel.org
ACPI: If "acpi_osi=Linux" works better, please notify linux-acpi@vger.kernel.org

2) System known to DMI, but effect of OSI(Linux) unknown:

ACPI: DMI detected: Lenovo ThinkPad T61
...
ACPI: BIOS _OSI(Linux) query ignored via DMI
ACPI: If "acpi_osi=Linux" works better, please notify linux-acpi@vger.kernel.org

3) System known to DMI, which disables _OSI(Linux):

ACPI: DMI detected: Lenovo ThinkPad T61
...
ACPI: BIOS _OSI(Linux) query ignored via DMI

4) System known to DMI, which enable _OSI(Linux):

ACPI: DMI detected: Lenovo ThinkPad T61

ACPI: BIOS _OSI(Linux) query honored via DMI

cmdline overrides take precidence over the built-in

IMHO, ACPI disabled due to DMI failure or blacklisted year should be noted,
as is done with other ACPI blacklisting.

This will help people troubleshoot when ACPI isn't working. Status quo is
a mysterious "ACPI Disabled" message without explanation on BIOS that
implements ACPI but not DMI. This is actually fairly common on embedded

[PATCH] x86_64: Clean up and tweak ACPI blacklist year code

- Move the core parser into dmi_scan.c. It can be useful for other
subsystems too.
- Differentiate between field doesn't exist and field is 0 or
unparseable. The first case is likely an old BIOS with broken ACPI,
the later is likely a slightly buggy BIOS where someone forget to
edit the date. Don't blacklist in the later case.

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
