The control method auto-serialization can interfere with existing
ASL code that makes use of Mutex/Method SyncLevel support. This
change makes the auto-serialization transparent to the SyncLevel

ACPICA commit 75c0da9e796bdf9bdd46d75f028a3e1779903214
In the error logs and debugger outputs, use new external path format that
does not contain a trailing underscore.
This patch takes care of acpi_ns_get_external_pathname() invocations, chaning
them into acpi_ns_get_normalized_pathname(TRUE) where possible. Along with some
error log fixes, the following debugger commands are fixed: resources,
handlers, paths. Lv Zheng.

applied with reduced human intervention.
The pscode.c has already been out of sync for months, and it becomes more

available for device driver.
Make available polarity and triggering information in acpi_find_gpio by
renaming acpi_gpio_info field active_low to polarity and adding triggering

The Dell Vostro V131 has an especially 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 has the same
problem).
Brightness keypresses reported through the acpi-video-bus are also broken,
they get reported one event delayed, so if you press the brightness-up
hotkey on the keyboard nothing happens, then if you press brightness-down,
the previous brightness-up event gets reported. Since the keypresses are
also reported via wmi (if active) and via atkbd (when wmi is not active)
add a quirk to simply filter out the delayed (broken) events.

Add a module option to disable the reporting of keypresses, in some buggy
firmware implementatinon, the reported events are wrong. E.g. they lag
reality by one event in the case triggering the writing of this patch.
In this case it is better to not forward these wrong events to userspace
(esp.) when there is another source of the same events which is not buggy.
Note this is only intended to work around implementations which send
events which are plain wrong. In some cases we get double events, e.g.
from both acpi-video and the atkbd driver, in this case acpi-video is
considered the canonical source, and the events from the other source
should be filtered (using e.g. /lib/udev/hwdb.d/60-keyboard.hwdb).

Several drivers want to know if the acpi-video is generating key-presses
for brightness change hotkeys to avoid sending double key-events to
userspace for these. Currently these driver use this construct for this:
if (acpi_video_get_backlight_type() == acpi_backlight_vendor)
report_brightness_key_event();
This indirect way of detecting if acpi-video is active does not make the
code easier to understand, and in some cases it is wrong because just
because the preferred type != vendor does not mean that acpi-video is
actually listening for brightness events, e.g. there may be no acpi-video
bus on the system at all.
This commit adds a acpi_video_handles_brightness_key_presses() helper
function, making the code needing this functionality both easier to read
and more correct.

Code currently supports 256 maximum interrupts at this moment. The patch is
reconfiguring the penalty array as a dynamic list to remove this
limitation.
A new penalty linklist has been added for all other interrupts greater than
16. If an IRQ is not found in the link list, an IRQ info structure will be
dynamically allocated on the first access and will be placed on the list
for further reuse. The list will grow by the number of supported interrupts
in the ACPI table rather than having a 256 hard limitation.
