This change fixes a problem where the constant folding code was not
invoked for arguments that compile to fixed-length constants (either
Byte, Word, DWord, or QWord.) ACPICA BZ 970.
This change adds a new _OSI string, "Windows 2012" for both Windows 8
and Windows Server 2012.
From Microsoft document "How to Identify the Windows Version in ACPI
by Using _OSI", July 13, 2012.
The generate/linux makefiles are obsolete and have been removed from
the unix tarball release packages. The replacement makefiles
are under generate/unix, and a top-level makefile under the main
acpica directory.
Update the comments that explain why ACPICA cannot use bitfields.
/*
* Note: C bitfields are not used for this reason:
*
* "Bitfields are great and easy to read, but unfortunately the C language
* does not specify the layout of bitfields in memory, which means they are
* essentially useless for dealing with packed data in on-disk formats or
* binary wire protocols." (Or ACPI tables and buffers.) "If you ask me,
* this decision was a design error in C. Ritchie could have picked an order
* and stuck with it." Norman Ramsey.

_PLD (Physical Location of Device) returns a bit-packed buffer that
is difficult to parse. This change adds a new interface,
AcpiDecodePldBuffer that parses the buffer into a more usable
local struct. Also adds macros to both get and set individual
fields within the packed _PLD buffer. Adds a new include file,
acbuffer.h - which will be expanded to add structs for other
ACPI names that return buffers. ACPICA BZ 954.
The original code was essentially a bug, so there is no need
to leave comments concerning the removal of the code.
Management of bus arbitration (ARB_DIS) must be performed in the
host C3 code.
ASLTS suite depends on the contents of SSDT1. The AcpiExec
definition of this table must match the ASLTS definition of the
same table, for DataTableRegion tests.
This change removes the code to disable/enable bus master
arbitration during suspend/resume. Use of the ARB_DIS
bit in the optional PM2_CNT register causes resume problems
on many machines.
Fixes a problem that can occur when a lone package object is
wrapped with an outer package object in order to conform to
the ACPI specification. Can affect these predefined names:
_ALR,_MLS,_PSS,_TRT,_TSS,_PRT,_HPX,_DLM,_CSD,_PSD,_TSD
Tables - emit additional information about the ACPI tables, including
the owner ID and flags decode.
Unload - reimplemented to use the new AcpiUnloadParentTable external
interface.
