Some Asus laptops (verified on X550VXK/FX502VD/FX502VE) get no
interrupts when pressing media keys thus the corresponding functions
are not invoked. It's due to the _GPE defines in DSDT for EC returns
differnt value compared to the GPE Number in ECDT. Confirmed with Asus
that the vale in ECDT is the correct one. This commit uses DMI quirks
to prevent calling _GPE when doing ec_parse_device() and keep the ECDT
GPE number setting for the EC device.

With previous commit, it is ensured that if there is an ECDT, it can
always be kept as boot_ec, this patch thus can implement a quirk on
top of the determined ECDT boot_ec.

We prepared _INI/_STA methods for \_SB, \_SB.PCI0, \_SB.LID0 and
\_SB.EC, _HID(PNP0C09)/_CRS/_GPE for \_SB.EC to poke Windows behavior
with qemu, we got the following execution sequence:

 \_SB._INI
 \_SB.PCI0._STA
 \_SB.LID0._STA
 \_SB.EC._STA
 \_SB.PCI0._INI
 \_SB.LID0._INI
 \_SB.EC._INI

There is no extra DSDT EC device enumeration process occurring before
the main ACPI device enumeration process. That means acpi_ec_dsdt_probe()
is not Windows-compatible.

Tracking back, it was added by the following commit:

  Commit: c5279dee
  Subject: ACPI: EC: Add some basic check for ECDT data

but that commit was misguided.

Why we shouldn't enumerate DSDT EC before the main ACPI device
enumeration?

The only way to know if the DSDT EC is valid would be to evaluate its
_STA control method, but it's not safe to evaluate this control method
that early and out of the ACPI enumeration process, because _STA may
refer to entities (such as resources or ACPI device objects) that may
not have been initialized before OSPM starts to enumerate them via
the main ACPI device enumeration.

But after we had reverted back to the expected behavior, a regression
was reported.  On that platform, there is no ECDT, but the platform
control methods access EC operation region earlier than Linux expects
causing some ACPI method execution errors. For this reason, we just
go back to old behavior to still probe DSDT EC as the boot EC.

However, that turns out to lead to yet another functional breakage
and in order to work around all of the problems, we skip boot stage
DSDT probe when the ECDT exists so that a later quirk can always use
correct ECDT GPE setting.

It's reported that some buggy BIOS tables can contain 2 DSDT ECs, one of
them is invalid but acpi_ec_dsdt_probe() fails to pick the valid one.
This patch simply enhances sanity checks in ec_parse_device() as a

The Dell Precision 7510 has a broken acpi-video implementation.

The backlight control bits work, but when the brightness is changed via
the acpi-video interface the backlight flickers annoyingly before settling
at the new brightness, switching to using the native interface fixes the
flickering so add a quirk for this (the vendor interface can not change the
brightness at all).

acpi_ec_cmd_string() currently is only enabled for "DEBUG" macro, but users
trend to use CONFIG_DYNAMIC_DEBUG and enable ec.c pr_debug() print-outs by
"dyndbg='file ec.c +p'". In this use case, all command names are turned
into UNDEF and the log is confusing. This affects bugzilla triage work.

This patch fixes this issue by enabling acpi_ec_cmd_string() for
CONFIG_DYNAMIC_DEBUG.

The EC event IRQ (SCI_EVT) can only be handled by submitting QR_EC. As the
EC driver handles SCI_EVT in a workqueue, after SCI_EVT is flagged and
before QR_EC is submitted, there is a period risking IRQ storming. EC IRQ
must be masked for this period but linux EC driver never does so.

No end user notices the IRQ storming and no developer fixes this known
issue because:

 1. The EC IRQ is always edge triggered GPE, and
 2. The kernel can execute no-op EC IRQ handler very fast.

For edge-triggered EC GPE platforms, it is only reported of post-resume EC
event lost issues, there won't be an IRQ storming. For level triggered EC
GPE platforms, fortunately the kernel is always fast enough to execute such
a no-op EC IRQ handler so that the IRQ handler won't be accumulated to
starve the task contexts, causing a real IRQ storming.

But the IRQ storming actually can still happen when:

 1. The EC IRQ performs like level triggered GPE, and
 2. The kernel EC debugging log is turned on but the console is slow enough.

There are more and more platforms using EC GPE as wake GPE where the EC GPE
is likely designed as level triggered. Then when EC debugging log is
enabled, the EC IRQ handler is no longer a no-op but dumps IRQ status to
the consoles. If the consoles are slow enough, the EC IRQs can arrive much
faster than executing the handler. Finally the accumulated EC event IRQ
handlers starve the task contexts, causing the IRQ storming to occur, and
the kernel hangs can be observed during boot/resume.

This patch fixes this issue by masking EC IRQ for this period:

 1. Begins when there is an SCI_EVT IRQ pending, and
 2. Ends when there is a QR_EC completed (SCI_EVT acknowledged).

A recent commit included linux/slab.h in linux/irq.h. This breaks the build
of vdso32 on a 64-bit kernel.

The reason is that linux/irq.h gets included into the vdso code via
linux/interrupt.h which is included from asm/mshyperv.h. That makes the
32-bit vdso compile fail, because slab.h includes the pgtable headers for
64-bit on a 64-bit build.

Neither linux/clocksource.h nor linux/interrupt.h are needed in the
mshyperv.h header file itself - it has a dependency on <linux/atomic.h>.

Remove the includes and unbreak the build.
