According to the reports, the "acpi_serialize" mechanism is broken as:
A. The parallel method calls can still happen when the interpreter lock is
released under the following conditions:
1. External callbacks are invoked, for example, by the region handlers,
the exception handlers, etc.;
2. Module level execution is performed when Load/LoadTable opcodes are
executed, and
3. The _REG control methods are invoked to complete the region
registrations.
B. For the following situations, the interpreter lock need to be released
even for a serialized method while currently, the lock-releasing
operation is marked as a no-op by
acpi_ex_relinquish/reacquire_interpreter() when this mechanism is
enabled:
1. Wait opcode is executed,
2. Acquire opcode is executed, and
3. Sleep opcode is executed.
This patch removes this mechanism and the internal
acpi_ex_relinquish/reacquire_interpreter() APIs. Lv Zheng.

Push and Pop are not portable "enough", and caused problems for
some ACPICA customers.

This change adds support for two missing objects, the "extra" and
"data" secondary objects, as well as adding support to traverse and
display linked lists related to ACPICA objects.

Use push and pop to both guarantee that the correct alignment is used,
and to restore the alignment to whatever it was before the header
was included.
It is reported that the #pragma pack(push/pop) directives are not supported
by the specific GCCs, but this patch still doesn't affect kernel build
as there are already #pragma pack([1]) directives used in the old ACPICA
headers, which means there shouldn't be GCCs that are currently used to
compile the ACPI kernels do not support #pragma pack() directives.

Some ASL compilers allow 64-bit constants within a 32-bit table
(DSDT version == 1). When encountered, emit a warning that the
constant will be truncated to 32 bits. This is potentially a
serious problem in the ACPI table(s).

Ignore an invalid space ID during a table load. Instead, detect it
if a control method attempts access - then abort the method.

This change will enable debug object output via a global variable,
acpi_gbl_enable_aml_debug_object. This will help with remote machine
debugging. Also, moved all debug object support code to a new
file, exdebug.c. Entire debug object module can now be
configured out of the ACPICA build if desired.

This type was introduced as the code was migrated from ACPI 1.0
(with 32-bit AML integers) to ACPI 2.0 (with 64-bit integers). It
is now obsolete and this change removes it from the ACPICA code
base, replaced by u64. The original typedef has been retained
for now for compatibility with existing device driver code.

Completed a major update for the acpi_get_object_info external interface.
Changes include:
- Support for variable, unlimited length HID, UID, and CID strings
- Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.)
- Call the _SxW power methods on behalf of a device object
- Determine if a device is a PCI root bridge
- Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
These changes will require an update to all callers of this interface.
See the ACPICA Programmer Reference for details.
Also, update all invocations of acpi_get_object_info interface
