Generic Serial Bus transfers use a data struct like this:
struct gsb_buffer {
u8 status;
u8 len;
u8 data[0];
};
acpi_ex_write_data_to_field() copies the data which is to be written from
the source-buffer to a temp-buffer. This is done because the OpReg-handler
overwrites the status field and some transfers do a write + read-back.
Commit f99b89eefeb6 ("ACPICA: Update for generic_serial_bus and
attrib_raw_process_bytes protocol") acpi_ex_write_data_to_field()
introduces a number of problems with this:
1) It drops a "length += 2" statement used to calculate the temp-buffer
size causing the temp-buffer to only be 1/2 bytes large for byte/word
transfers while it should be 3/4 bytes (taking the status and len field
into account). This is already fixed in commit e324e10109fc ("ACPICA:
Update for field unit access") which refactors the code.
The ACPI 6.0 spec (ACPI_6.0.pdf) "5.5.2.4.5.2 Declaring and Using a
GenericSerialBusData Buffer" (page 232) states that the GenericSerialBus
Data Buffer Length field is only valid when doing a Read/Write Block
(AttribBlock) transfer, but since the troublesome commit we unconditionally
use the len field to determine how much data to copy from the source-buffer
into the temp-buffer passed to the OpRegion.
This causes 3 further issues:
2) This may lead to not copying enough data to the temp-buffer causing the
OpRegion handler for the serial-bus to write garbage to the hardware.
3) The temp-buffer passed to the OpRegion is allocated to the size
returned by acpi_ex_get_serial_access_length(), which may be as little
as 1, so potentially this may lead to a write overflow of the temp-buffer.
4) Commit e324e10109fc ("ACPICA: Update for field unit access") drops a
length check on the source-buffer, leading to a potential read overflow
of the source-buffer.
This commit fixes all 3 remaining issues by not looking at the len field at
all (the interpretation of this field is left up to the OpRegion handler),
and copying the minimum of the source- and temp-buffer sizes from the
source-buffer to the temp-buffer.
This fixes e.g. an Acer S1003 no longer booting since the troublesome
commit.

acpi_gbl_execute_tables_as_methods instead
acpi_gbl_group_module_level_code and acpi_gbl_execute_tables_as_methods were
used to enable different table load behavior. The different table
load behaviors are as follows:
A.) acpi_gbl_group_module_level_code enabled the legacy approach where
ASL if statements are executed after the namespace object has
been loaded.
B.) acpi_gbl_execute_tables_as_methods is currently used to enable the
table load to be a method invocation. This meaning that ASL If
statements are executed in-line rather than deferred until after
the ACPI namespace has been populated. This is the correct
behavior and option A will be removed in the future.
We do not support a table load behavior where these variables are
assigned the same value. In otherwords, we only support option A or B
and do not need acpi_gbl_group_module_level_code to enable A. From now on,
acpi_gbl_execute_tables_as_methods == 0 enables option A and
acpi_gbl_execute_tables_as_methods == 1 enables option B.
Note: option A is expected to be removed in the future and option B
will become the only supported table load behavior.

AML opcodes come in two lengths: 1-byte opcodes and 2-byte, extended opcodes.
If an error occurs due to illegal opcodes during table load, the AML parser
needs to continue loading the table. In order to do this, it needs to skip
parsing of the offending opcode and operands associated with that opcode.
This change fixes the AML parse loop to correctly skip parsing of incorrect
extended opcodes. Previously, only the short opcodes were skipped correctly.

initialization
The table load process omitted adding the operation region address
range to the global list. This omission is problematic because the OS
queries the global list to check for address range conflicts before
deciding which drivers to load. This commit may result in warning
messages that look like the following:
[ 7.871761] ACPI Warning: system_IO range 0x00000428-0x0000042F conflicts with op_region 0x00000400-0x0000047F (\PMIO) (20180531/utaddress-213)
[ 7.871769] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
However, these messages do not signify regressions. It is a result of
properly adding address ranges within the global address list.

Commit fa85015c0d95 (ACPICA: Clear status of all events when entering
S5) made the sleep state entry code in ACPICA clear the status of all
ACPI events when entering S5 to fix a functional regression reported
against commit 18996f2db918 (ACPICA: Events: Stop unconditionally
clearing ACPI IRQs during suspend/resume). However, it is reported
now that the regression also affects system states other than S5 on
some systems and causes them to wake up from sleep prematurely.
For this reason, make the code in question clear the status of all
ACPI events when entering all sleep states (in addition to S5) to
avoid the premature wakeups (this may cause some wakeup events to
be missed in theory, but the likelihood of that is small and the
change here simply restores the previous behavior of the code).

Field elements listed in the init file used to be initialized after
the table load and before executing module-level code blocks. The
recent changes in module-level code mean that the table load becomes
a method execution. If fields are used within module-level code and
we are executing with -fi option, then these values are populated
after the table has finished loading. This commit changes the
initialization of objects listed in the init file so that field unit
values are populated during the table load.

Previous change in the AML parser code blindly set all non-successful
dispatcher statuses to AE_OK. That approach is incorrect, though,
because successful control method invocations from module-level
return AE_CTRL_TRANSFER. Overwriting AE_OK to this status causes the
AML parser to think that there was no return value from the control
method invocation.

The dispatcher and the executer process the parse nodes During table
load. Error status from the evaluation confuses the AML parser. This
results in the parser failing to complete parsing of the current
scope op which becomes problematic. For the incorrect AML below, _ADR
never gets created.
definition_block(...)
{
Scope (\_SB)
{
Device (PCI0){...}
Name (OBJ1, 0x0)
OBJ1 = PCI0 + 5 // Results in an operand error.
} // \_SB not closed
// parser looks for \_SB._SB.PCI0, results in AE_NOT_FOUND error
// Entire scope block gets skipped.
Scope (\_SB.PCI0)
{
Name (_ADR, 0x0)
}
}
Fix the above error by properly completing the initial \_SB scope
after an error by clearing errors that occur during table load. In
the above case, this means that OBJ1 = PIC0 + 5 is skipped.

After commit 18996f2db918 (ACPICA: Events: Stop unconditionally
clearing ACPI IRQs during suspend/resume) the status of ACPI events
is not cleared any more when entering the ACPI S5 system state (power
off) which causes some systems to power up immediately after turing
off power in certain situations.
That is a functional regression, so address it by making the code
clear the status of all ACPI events again when entering S5 (for
system-wide suspend or hibernation the clearing of the status of all
events is not desirable, as it might cause the kernel to miss wakeup
events sometimes).

upon an error.
Notable changes:
If there is an error while parsing an element of the termlist, we
will skip parsing the current termlist element and continue parsing
to the next opcode in the termlist.
If we get an error while parsing the conditional of If/Else/While or
the device name of Scope, we will skip the body of the statement all
together and pop the parser_state.
If we get an error while parsing the base offset and length of an
