66e42ee57c ACPICA: Reduce regression fix divergence from upstream ACPICA
Linux has been fixed during 20151218 release cycle by reverting wrong code
in the following commit:
  ACPICA commit: 071eff738c59eda1792ac24b3b688b61691d7e7c
  Subject: Add per-table execution of module-level code, early region
           handlers
While upstream ACPICA fixes later in the following commit:
  ACPICA commit: bf6cfddb4784c349f781758981b207253b5a1252
  Subject: Fix for module-level-code regression introduced in 20151218

This results in the divergences and this patch is meant to reduce such
divergences. Lv Zheng.

14e9355363 ACPI / video: Fix using an uninitialized mutex / list_head in acpi_video_handles_brightness_key_presses()
If acpi_video_handles_brightness_key_presses() was called before
acpi_video_register(), it would use the video_list mutex / list_head
uninitialized.

This patch fixes this by using DEFINE_MUTEX / LIST_HEAD when declaring
these, instead of initializing them runtime from acpi_video_register().

970530cd00 ACPI / video: Revert "ACPI / video: driver must be registered before checking for keypresses"
On systems with an intel video opcode region, the completion used in the
patch this commit reverts will only complete if the i915 driver loads.

If for some reason the i915 driver never loads calls to
acpi_video_handles_brightness_key_presses() may be delayed indefinitely.

This reverts commit aecbd9b1bf ("ACPI / video: driver must be registered
before checking for keypresses") fixing this.

This reintroduces a potential NULL pointer deref due to using an
uninitalized mutex, this is fixed differently in a follow-up patch.

989561de9b PM / Domains: add setter for dev.pm_domain
Adds a function that sets the pointer to dev_pm_domain in struct device
and that warns if the device has already finished probing. The reason
why we want to enforce that is because in the general case that can
cause problems and also that we can simplify code quite a bit if we can
always assume that.

This patch also changes all current code that directly sets the
dev.pm_domain pointer.

eebb3e8d8a ACPI / LPSS: override power state for LPSS DMA device
This is a third approach to workaround long standing issue with LPSS on
BayTrail. First one [1] was reverted since it didn't resolve the issue
comprehensively. Second one [2] was rejected by internal review.

The LPSS DMA controller does not have neither _PS0 nor _PS3 method. Moreover it
can be powered off automatically whenever the last LPSS device goes down. In
case of no power any access to the DMA controller will hang the system. The
behaviour is reproduced on some HP laptops based on Intel BayTrail [3,4] as
well as on ASuS T100TA transformer.

Power on the LPSS island through the registers accessible in a specific way.

aecbd9b1bf ACPI / video: driver must be registered before checking for keypresses
acpi_video_handles_brightness_key_presses() may use an uninitialized mutex.
The error has been reported by lockdep: DEBUG_LOCKS_WARN_ON(l->magic != l).
The function assumes that the video driver has been registered before being
called. As explained in the comment of acpi_video_init(), the registration
of the video class may be defered and thus may not take place in the init
function of the module.

Use completion mechanisms to make sure that
acpi_video_handles_brightness_key_presses() wait for the completion of
acpi_video_register() before using the mutex.
Also get rid of register_count since task completion can replace it.

e3e9b577b4 ACPICA: Drop Linux-specific waking vector functions
Commit f06147f9fb (ACPICA: Hardware: Enable firmware waking vector
for both 32-bit and 64-bit FACS) added three functions that aren't
present in upstream ACPICA, acpi_hw_set_firmware_waking_vectors(),
acpi_set_firmware_waking_vectors() and acpi_set_firmware_waking_vector64(),
to allow Linux to use the previously existing API for setting the
platform firmware waking vector.

However, that wasn't necessary, since the ACPI sleep support code
in Linux can be modified to use the upstream ACPICA's API easily
and the additional functions may be dropped which reduces the code
size and puts the kernel's ACPICA code more in line with the upstream.

Make the changes as per the above.  While at it, make the relevant
function desctiption comments reflect the upstream ACPICA's ones.

Execute any module-level code after each ACPI table (DSDT or SSDT)
is loaded into the namespace (rather than after all AML tables have
been loaded).  This matches the behavior of other ACPI
implementations and is required to support BIOS code that

d815346f76 ACPICA: Events: Introduce ACPI_REG_DISCONNECT invocation to acpi_ev_execute_reg_methods()
ACPICA commit 1cf1a1e090f61f0c27f1dcf1905c7cc79a9c51c8

It is likely that we should synchronously invoke _REG(DISCONNECT) only when
the acpi_remove_address_space_handler() is invoked because of dependencies.
If it is invoked when the object is not referenced, problem may occur
if the operation region fields accessed in _REG are no longer driven by any
device driver.

Noticed that _REG(CONNECT)/_REG(DISCONNECT) only mean to inform the AML of
the handler availability, no return value is required for the caller.

This patch only introduces ACPI_REG_DISCONNECT invaocation, but doesn't
introduce a real change. Lv Zheng.

ACPICA commit 31178590dde82368fdb0f6b0e466b6c0add96c57

We can ensure no early _REG evaluations by ensuring the following rules in
acpi_ev_execute_reg_method():
1. If an address space handler is installed during early stage,
   _REG(CONNECT) evaluations are blocked. This is achieved using
   acpi_gbl_reg_methods_enabled which is renamed from
   acpi_gbl_reg_methods_executed.
2. If _REG(CONNECT) has never been evalauted for the region object,
   _REG(DISCONNECT) evaluations are blocked. This is achieved by a new
   region object flag: AOPOBJ_REG_CONNECTED.
Note that, after applying this patch, we can ensure _REG(DISCONNECT) is
always paired to _REG(CONNECT). Lv Zheng

849c25719a ACPICA: Events: Split acpi_ev_associate_reg_method() from region initialization code
ACPICA commit 87c85610250ff7141a84507f68dbc1e00f2936db

This patch introduces a new region initialization function
acpi_ev_associate_reg_method(), which is invoked to associate the _REG method
to its related region object.

Region object's default value assignments are also sorted by cleaning up
the code using this new function. Lv Zheng.

ACPICA commit 6ebcb24d3225b6c7715a3ce061c327b4c3a6b76e

The logic in acpi_ev_attach_region() is not correct, it can break address
space handler link. This patch fixes this problem. But be aware that this
fix must be applied along with a region object race issue fix. Lv Zheng.

2e1beaf6a9 ACPICA: Utilities: Reorder initialization code
ACPICA commit 3894fa9d071343e6ebc7ea480255fa4f27a290be

This patch re-orders initialization code in acpi_enable_subsystem()
so that all hardware reduced stuffs can be collected together.

Note this patch contains code from the following 2 ACPICA upstream commits
so that the changes can be made clearer for the reviewers:
 https://github.com/acpica/acpica/commit/071eff73
 https://github.com/acpica/acpica/commit/3894fa9d
And additional change to remove the global variable and unused code
fragments due to the test result. Lv Zheng.

cca7a6ea0b ACPICA: Update parameter type for ObjectType operator
ACPICA commit 67953304a34944548f2fa53a4b0786a5db0ca2ea

The grammar for this operator changed in ACPI 5.0A, but it was
not necessary to update the interpreter/parser until now.

The UserTerm (method invocation) element was removed. Previously
a SuperName, the lone argument now requires a new ARGP_ type.

SuperName parameters that are in fact control method invocations were
not handled correctly by the parser. This change fixes the problem
by identifying these properly as method invocations. This affects
about 14 different ASL operators that contain SuperName parameters.

ACPICA commit 918a840d27d620942e0ecb69de320bb71ea86c5a

ElseIf is a macro that resolves to an Else..If in the AML byte code.
This support merges an Else followed immediately by an If to an
ASL ElseIf operator. Simplifies decoded ASL, especially for large
Switch statements.

This patch only applies to iasl, and is no-op for Linux kernel.

ACPICA commit 80e60d72959bb51c5d08c8500d978607a42ed81d

BIOS developers may accidently put the quotes around the name strings,
which converts the object references in the packages indicated by the name
strings into the data objects (strings). Such kind of error has been seen
in _DEP control methods on some platforms. This patch implements a
workaround to correct it. Reported by Bastien Nocera. Fixed by Lv Zheng.
