From b3c86c30efd83ebfa7010c5890e2ebf2678e49f8 Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Tue, 29 Oct 2013 09:29:27 +0800 Subject: ACPICA: Cleanup memory allocation macros and configurability. 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 enables the host OS to redefine OSL prototypes found in the acpiosxf.h file. This allows the host OS to implement OSL interfaces with a macro or inlined function. Further, it allows the host OS to add any additional required modifiers such as __iomem, __init, __exit, etc., as necessary on a per-interface basis. Enables maximum flexibility for the OSL interfaces. Lv Zheng. Signed-off-by: Lv Zheng Signed-off-by: Bob Moore Signed-off-by: Rafael J.

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.
