For Linux, there are no functional changes/binary generation differences introduced by this patch. This change adds a new macro to all files that contain external ACPICA interfaces. It can be detected and used by the host (via the host-specific header) for any special processing required for such modules. Lv Zheng.

The ACPI spec requires the reset register width to be 8, so we now hardcode it and ignore the FADT value.

In the common case, the ACPI_ALLOCATE and related macros now resolve directly to their respective acpi_os* OSL interfaces. Two options: 1) The ACPI_ALLOCATE_ZEROED macro defaults to a simple local implementation by default, unless overridden by the USE_NATIVE_ALLOCATE_ZEROED define. 2) For ACPI execution simulation environment (AcpiExec) which is not shipped with the Linux kernel, the macros can optionally be resolved to the local interfaces that track each allocation (used to immediately detect memory leaks).

This change adds and deploys "safe" versions of strcpy and strcat that ensure that the target buffer does not overflow. These safe functions are only helpful for processing user input and command lines. For most ACPICA code however, the required buffer length is precisely calculated before buffer allocation, so the use of these functions is unnecessary. ACPICA BZ 1043. This change only applies to the ACPICA utilities and the debugger, none of which are not shipped with the kernel yet, so the kernel's behavior remains unchanged after it.

The original upstream ACPICA change added full history and limited line editing to the debugger: This change adds full history and limited line editing for Unix and Linux systems. It does not use readline() because of portability issues. Instead it uses the POSIX termio interface to put the terminal in raw input mode so that the various special keys can be trapped (such as up-arrow and down-arrow for history support). Since the debugger is not shipped in the kernel, it only is necessary to update one header file to keep the kernel source in sync with the upstream.

This change removes some dangerous code that attempts to free the handler context pointer in some (rare) circumstances. The owner of the handler owns this pointer and the ACPICA code should never touch it. Although not seen to be an issue in any kernel, it did show up as a problem under AcpiExec.

This change adds support to allow hosts to install System Control Interrupt handlers. Certain ACPI functionality requires the host to handle raw SCIs. For example, the "SCI Doorbell" that is defined for memory power state support requires the host device driver to handle SCIs to examine if the doorbell has been activated. Multiple SCI handlers can be installed to allow for future expansion. Debugger support is included. Lv Zheng, Bob Moore. ACPICA BZ 1032. Bug summary: It is reported when the PCC (Platform Communication Channel, via MPST table, defined in ACPI specification 5.0) subchannel responds to the host, it issues an SCI and the host must probe the subchannel for channel status.

Previously, references to these objects were resolved only to the actual FieldUnit or BufferField object. The correct behavior is to resolve these references to an actual value. The problem is that DerefOf did not resolve these objects to actual values. An "Integer" object is simple, return the value. But a field in an operation region will require a read operation. For a BufferField, the appropriate data must be extracted from the parent buffer. NOTE: It appears that this issues is present in Windows7 but not Windows8.

ACPICA does not have the knowledge about whether an _OSI interface string is an OS vendor string or a feature group string and there isn't any API interface to allow OSPM to install a new interface string as a feature group string. This patch simply adds all feature group strings defined by ACPI specification into the acpi_default_supported_interfaces with ACPI_OSI_FEATURE flag set to fix this gap.
