Nothing big, really:

* The licensing information at the start of each source code module has
been updated. In addition to the Intel license, the dual GPLv2/BSD
license has been added for completeness. Now, a single version of the
source code should be suitable for all ACPICA customers. This is the
major change for this release since it affects all source code modules.

* Fixed two issues with the common asltypes.h header that could cause
problems in some environments (Kim Jung-uk).

* Disassembler: fixed a regression introduced in 20170224. A fix for a
memory leak related to resource descriptor tags (names) could fault
when the disassembler was generated with 64-bit compilers.

* Fixed a regression where occasionally a valid resource
descriptor was incorrectly detected as invalid at runtime,
and a AE_AML_NO_RESOURCE_END_TAG was returned.

* Fixed a problem with the recently implemented support that
enables control method invocations as Target operands to
many ASL operators. Warnings of this form: "Needed type
[Reference], found [Processor]" were seen at runtime for
some method invocations.

This is the proper fix for 72b7bc0a284cc.

in AcpiHwRead/AcpiHwWrite for the Generic Address Structure. There

fully resolved and tested before this support can be finally
integrated into ACPICA. Apologies for any inconveniences these
issues may have caused.

ACPI_MSG_EXCEPTION, ACPI_MSG_WARNING, ACPI_MSG_INFO,
ACPI_MSG_BIOS_ERROR, and ACPI_MSG_BIOS_WARNING). Lv Zheng.

Sync ACPICA with Intel's version 20160108.

This includes the 20151218 upgrade which we had to revert again because
of a bug found by tkusumi. The only major change in 20160108 is a fix
for this bug.

20151218 changes:

* Execute "module-level code" as ACPI tables are loaded into the
namespace during initialization and install the default operation
region handlers for the SystemMemory, SystemIO and PCI_Config
address spaces before any ACPI tables are loaded (in order to
enable module-level code to access these address spaces). Also,
several changes to the internal _REG support and to utilities
in conjunction with these changes.

20160108 changes:

* Fixed a regression introduced in version 20151218 concerning the
execution of so-called module-level ASL/AML code. Namespace objects
created under a module-level If() construct were not properly/fully
entered into the namespace and could cause an interpreter fault when
accessed.

* Fixed a problem with the compilation of the GpioIo and GpioInt resource
descriptors. The _PIN field name was incorrectly defined to be an array
of 32-bit values, but the _PIN values are in fact 16 bits each. This
would cause incorrect bit width warnings when using Word (16-bit) fields
to access the descriptors.

Additionally, some minor fixes, features etc. were added.

for the ASL compiler).

kernel: Sync ACPICA with Intel's version 20140325.

As far as I can see, the most important change is a fix for the auto-
serialization of control methods so that the currently executing AML
SyncLevel is ignored when invoking such a method. This fixes an issue
seen in some systems showing AE_AML_MUTEX exceptions since 20140214
which had to set hw.acpi.auto_serialize_methods to 0 to work around
the issue.

This was actually reported for DragonFly by Andrey Oktyabrskiy (see
http://lists.dragonflybsd.org/pipermail/users/2014-February/109376.html).

kernel: Sync ACPICA with Intel's version 20140214.

Module changes:

* Implemented a new mechanism to proactively prevent problems with
ill-behaved reentrant control methods that create named ACPI objects.
It should allow serialization of methods without leading to
AE_ALREADY_EXISTS exceptions if the method was actually entered by
more than one thread.

* Added the "Windows 2013" string to the _OSI support.

* Hardened/updated the _PRT return value auto-repair code.

* Added support to avoid the possibility of infinite loops when
traversing object linked lists.

* Add #pragma pack({push,pop}) to ensure that ACPICA headers are
independent of compiler settings or host headers.

Utilities changes:

* iasl(8): Fix a problem with support for the SPMI table. The first
reserved field was incorrectly forced to have a value of zero
instead of one.

* iasl(8): Removed the obsolete -g option.

* acpiexec(8): Added missing support for "Extra" and "Data" subobjects
and for diplaying entire object linked lists.

For a more detailed list, see sys/contrib/dev/acpica/changes.txt.

As of this commit, the hw.acpi.serialize_methods tunable (0 by default)
is replaced with hw.acpi.auto_serialize_methods (1 by default). Users
with the former tunable set to 1 in their loader.conf should therefore
not experience any differences.
