2013-11-26ACPI: Clean up incorrect inclusions of ACPICA headersLv Zheng2-2/+0
Header file <acpi/acpi.h> contains environemnt settings and architecture specific implementation that should be included before any other ACPICA headers in order to keep a consistent build environment for ACPICA users. The following internal ACPICA header files should be included from <acpi/acpi.h> and should not be included by other kernel files: <acpi/acpiosxf.h> <acpi/acpixf.h> Clean up incorrect inclusions of these files from non-ACPICA source files.

The loop terminates on a NULL resource pointer, which can never happen since the loop simply increments a valid resource pointer. This fix changes the loop to terminate on an end-of-buffer condition. Problem can be seen by callers to AcpiSetCurrentResources with an invalid or corrupted resource descriptor; or a resource descriptor without an END_TAG descriptor.

2013-10-31ACPICA: Update aclinux.h for new OSL override mechanism.Lv Zheng2-45/+91
The new ACPICA OSL override mechanism is used to solve these issues for the Linux OSL: 1. Linux can implement OSL using a macro. 2. Linux can implement OSL using an inlined function. 3. Linux can leave OSL not implemented for __KERNEL__ undefined code fragments. 4. Linux can add sparse declarators (__iomem) to OSL. 5. Linux can add memory tuning declarators (__init/__exit) to OSL. This patch also moves Linux specific OSL to aclinux.h which has not been maintained in the ACPICA code base. Lv Zheng. Known issue: From ACPICA's perspective, actypes.h should be included after inclusion of acenv.h. But currently in Linux, aclinux.h included by acenv.h has included actypes.h to find ACPICA types for inline functions. This is a known and existing issue and currently there is no real problem caused by this issue for Linux kernel build. Thus this issue is not covered by this cleanup commit.

2013-10-31ACPICA: Fix indentation issues for macro invocations.Lv Zheng5-8/+25
During the automatic translation of the upstream ACPICA source code into Linux kernel source code some extra white spaces are added by the "indent" program at the beginning of each line which is an invocation of a macro and there is no ";" at the end of the line. For this reason, a new mode has been added to the translation scripts to remove the extra spaces inserted before invoking such macros and add an empty line between the invocations of such macros (like the other function declarations). This new mode is executed after executing "indent" during the Linux release process. Consequently, some existing ACPICA source code in the Linux kernel tree needs to be adjusted to allow the new scripts to work correctly. The affected macros and files are: 1. ACPI_HW_DEPENDENT_RETURN (acpixf.h/acdebug.h/acevents.h): This macro is used as a wrapper for hardware dependent APIs to offer a stub when the reduced hardware is configured during compilation. 2. ACPI_EXPORT_SYMBOL (utglobal.c): This macro is used by Linux to export symbols to be found by Linux modules. All such invocations are well formatted except those exported as global variables. This can help to reduce the source code differences between Linux and upstream ACPICA, and also help to automate the release process. No functional or binary generation changes should result from it.

interfaces. This changes can reduce source code differences between Linux and ACPICA upstream to help improving the release automation. The side effect of applying this patch in Linux is: 1. Some ACPICA initialization/termination APIs are no longer exported in Linux, these include: acpi_load_tables acpi_initialize_subsystem acpi_enable_subsystem acpi_initialize_objects acpi_terminate 2. This patch does not affect the following APIs as they are currently not marked with ACPI_EXPORT_SYMBOL in Linux: acpi_reallocate_root_table acpi_initialize_tables Such functions should not be exported as they are internal to ACPI subsystem in Linux, and will only be invoked inside of ACPI subsystem's initialization routines marked with __init and termination routines marked with __exit. While on other OSPMs, such functions may still need to be exported. Thus this patch adds the configurability for ACPICA, so that it leaves OSPMs to determine if the __init/__exit marked functions should be exported or not. Lv Zheng.

2013-09-24ACPICA: Operation region support: Never free the handler "context" pointer.David E. Box1-10/+13
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. Also, set the internal storage field for the context pointer to zero when the region is deactivated, simply for sanity. David Box. Signed-off-by: David E.
