acpi_graph_get_child_prop_value() is intended to find a child node with a
certain property value pair. The check
if (!fwnode_property_read_u32(fwnode, prop_name, &nr))
continue;
is faulty: fwnode_property_read_u32() returns zero on success, not on
failure, leading to comparing values only if the searched property was not
found.
Moreover, the check is made against the parent device node instead of
the child one as it should be.

Commit 2d2a954375a0 (ACPICA: Update two error messages to emit
control method name) causes acpi_evaluate_object_typed() to fail
if its pathname argument is NULL, but some callers of that function
in the kernel, particularly acpi_nondev_subnode_data_ok(), pass
NULL as pathname to it and expect it to work.
For this reason, make acpi_evaluate_object_typed() check if its
pathname argument is NULL and fall back to using the pathname of
its handle argument if that is the case.

Commit 2a5708409e4e (ACPI / EC: Fix a gap that ECDT EC cannot handle
EC events) introduced acpi_ec_ecdt_start(), but that function is
invoked before acpi_ec_query_init(), which is too early. This causes
the kernel to crash if an EC event occurs after boot, when ec_query_wq
is not valid:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000102
...
Workqueue: events acpi_ec_event_handler
task: ffff9f539790dac0 task.stack: ffffb437c0e10000
RIP: 0010:__queue_work+0x32/0x430
Normally, the DSDT EC should always be valid, so acpi_ec_ecdt_start()
is actually a no-op in the majority of cases. However, commit
c712bb58d827 (ACPI / EC: Add support to skip boot stage DSDT probe)
caused the probing of the DSDT EC as the "boot EC" to be skipped when
the ECDT EC is valid and uncovered the bug.
Fix this issue by invoking acpi_ec_ecdt_start() after acpi_ec_query_init()
in acpi_ec_init().

ACPICA commit 01b8f5a2350b9cc329cd8402ac8faec36fc501f5
In order to build ACPICA EFI tools with EDK-II on Windows, 64-bit
multiply/shift supports are also required to be implemented. Otherwise,
MSVC complains:
acpidump.lib(utstrtoul64.obj) : error LNK2001: unresolved external symbol __allmul

Note:
1. This patch also splits _EDK2_EFI from _GNU_EFI as they might have
different math64 supports.
2. Support of gcc math64 is not included in this patch.
3. Support of EDK2 arch independent math64 is done via linking to base_lib.
This patch fixes this issue. Reported by Shao Ming, fixed by Lv Zheng.

ACPICA commit cf27b3c98883d2a15d932016792fcb8272ace96d
The following commit introduces definition of access width to ACPICA.
Commit: 2bece49394872d36bbc5767fd643deac05920c55
Subject: ACPI: SPCR: Use access width to determine mmio usage
Actually the access bit width can be calculated via access width. It
would be better to define a macro calculating bit width rather than
defining fixed values. This patch thus cleans up the definitions to
reduce divergences.

The work-around for Qualcomm Technologies QDF2400 Erratum 44 hinges on a
global variable defined in the pl011 driver. The ACPI SPCR parsing code
determines whether the work-around is needed, and if so, it changes the
console name from "pl011" to "qdf2400_e44". The expectation is that
the pl011 driver will implement the work-around when it sees the console
name. The global variable qdf2400_e44_present is set when that happens.
The problem is that work-around needs to be enabled when the pl011
driver probes, not when the console name is queried. However, sbsa_probe()
is called before pl011_console_match(). The work-around appeared to work
previously because the default console on QDF2400 platforms was always
ttyAMA1. The first time sbsa_probe() is called (for ttyAMA0),
qdf2400_e44_present is still false. Then pl011_console_match() is called,
and it sets qdf2400_e44_present to true. All subsequent calls to
sbsa_probe() enable the work-around.
The solution is to move the global variable into spcr.c and let the
pl011 driver query it during probe time. This works because all QDF2400
platforms require SPCR, so parse_spcr() will always be called.
pl011_console_match still checks for the "qdf2400_e44" console name,
but it doesn't do anything else special.
Fixes: 5a0722b898f8 ("tty: pl011: use "qdf2400_e44" as the earlycon name for QDF2400 E44")

Commit eed4d47efe95 (ACPI / sleep: Ignore spurious SCI wakeups from
suspend-to-idle) introduced acpi_freeze_sync() whose purpose is to
flush all of the processing of possible wakeup events signaled via
the ACPI SCI. However, it doesn't flush the query workqueue used
by the EC driver, so the events generated by the EC may not be
processed timely which leads to issues (increased overhead at least,
lost events possibly).
To fix that introduce acpi_ec_flush_work() that will flush all of
the outstanding EC work and call it from acpi_freeze_sync().

ACPICA commit 8b14afac65d983610cc5387ede6d85ea5ee075be
The following ACPI table contains an invalid target node within the
Alias operator:
definition_block ("", "SSDT", 1, "Bug", "BugTable", 0x00001000)
{
Scope (_SB)
{
Device (DEV0)
{
Name (_ADR, 1)
Device (DEV1)
{
Alias (_ADR, _ADR)
}
}
}
}
If an ACPI table contains such an invalid target node in an Alias
operator, a segmentation fault will occur when the target node is
dereferenced within acpi_ex_create_alias. Add a check for such an invalid
target node in acpi_ex_create_alias and return AE_NULL_OBJECT as suggested
by @acpibob.

ACPICA commit 894e49ef22db354eb1685cdb6f5f991766351d3c
acpisrc now has capability to convert both the followings:
1. Form 1:
typedef struct/union foo { struct/union foo {
.... --> ...
} FOO; }
2. Form 2:
typedef struct/union foo FOO; --> typedef struct/union foo foo;
It becomes unable to handle the following:
3. Form3:
typedef struct/union foo { /* comment */
...
} FOO;
-->
strut/union foo { /* comment */
...
};
As:
1. The purpose of acpisrc is to convert formatted code (ACPICA coding
style) into linux coding style,
2. acpisrc is a very simple tool that doesn't fully handle C language.
This commit changes the definitions side in order not to regress and we
shall make "no comments in struct/union line" as a new ACPICA coding style
rule. Lv Zheng.

After commit 8110dd281e15 (ACPI / sleep: EC-based wakeup from
suspend-to-idle on recent systems) the configuration of GPEs,
including the EC one, is not changed during suspend-to-idle on
recent systems. That's in order to make system wakeup events
generated by the EC work, in particular.
However, on some of the systems in question (for example on Dell
XPS13 9365), in addition to generating system wakeup events the
EC generates a heartbeat sequence of interrupts that have nothing
to do with wakeup while suspended, and the Low Power Idle S0 _DSM
interface doesn't change that behavior.
The users of those systems may prefer to disable the EC GPE during
system suspend, for the cost of non-functional power button wakeup
or similar, but currently there is no way to do that.
For this reason, add a new module parameter, ec_no_wakeup, for the
EC driver module that, if set, will cause the EC GPE to be disabled
during system suspend and re-enabled during the subsequent system
resume.

nfit_init() calls nfit_mce_register() on module load. When the module
load fails the nfit mce decoder is not unregistered. The module's
memory is freed leaving the decoder chain referencing junk. This will
cause panics as future registrations will reference the free'd memory.
Unregister the nfit mce decoder on module init failure.
[v2]: register and then unregister mce handler to avoid losing mce events
[v3]: also cleanup nfit workqueue

The _STA method of the Venue 11 Pro 7130 touchscreen has this ugliness:
Method (_STA, 0, NotSerialized) // _STA: Status
{
If ((SDS1 & One) == One)
{
If (RST1 == Zero)
{
Return (0x0F)
}
ElseIf (RST2 == Zero)
{
RST2 = One
TMRV = Timer
}
Else
{
Local0 = ((Timer - TMRV) / 0x2710)
If (Local0 > TMRI)
{
RST2 = Zero
RST1 = Zero
}
}
}
Else
{
Return (Zero)
}
}
Whereby RST1 gets set by _SB.PCI0.GFX0.LCD.LCD1._ON, this means that
after RST1 has been set first _STA must be called to set TIMER and
then after enough time has elapsed _STA must be called twice more, once
to clear RST1 and once to finally return 0xf before the touchscreen will
show up. Which is just crazy.
This commit adds an always_present_ids entry for the SYNA7500 touchscreen

touchscreen not working on this device.

On some x86 systems the DSDT hides APCI devices to work around Windows
driver bugs. On one such system the device is even hidden until a certain
time after _SB.PCI0.GFX0.LCD.LCD1._ON gets called has passed *and*
_STA has been called at least 3 times since. TL;DR: it is a mess.
Until now the always_present_id matching was used to force status
for a whole class of devices, e.g. always enable PWM1 on CHerry Trail
devices.
This commit extends the always_present_id matching code to optionally
also check for a DMI match so that we can also add system specific
quirks to the always_present_id array.

On Lenovo ThinkPad X1 Carbon - the 5th Generation, enabling an earlier
EC event freezing timing causes acpitz-virtual-0 to report a stuck
48C temparature. And with EC firmware revisioned as 1.14, without
reverting back to old EC event freezing timing, the fan still blows
up after a system resume.
This reverts the culprit change so that the regression can be fixed
without upgrading the EC firmware.

According to bug reports, although the busy polling mode can make
noirq stages execute faster, it causes abnormal fan blowing up after
system resume (see the first link below for a video demonstration)
on Lenovo ThinkPad X1 Carbon - the 5th Generation. The problem can
be fixed by upgrading the EC firmware on that machine.
However, many reporters confirm that the problem can be fixed by
stopping busy polling during suspend/resume and for some of them
upgrading the EC firmware is not an option.
For this reason, drop the noirq stage hooks from the EC driver
to fix the regression.
