From ACPICA's perspective, <acpi/actypes.h> should be included after inclusion of <acpi/platform/acenv.h>. But currently in Linux, <acpi/platform/aclinux.h> included by <acpi/platform/acenv.h> has included <acpi/actypes.h> to find ACPICA types for inline functions. This causes the following problem: 1. Redundant code in <asm/acpi.h> and <acpi/platform/aclinux.h>: Linux must be careful to keep conditions for <acpi/actypes.h> inclusion consistent with the conditions for <acpi/platform/aclinux.h> inclusion. Which finally leads to the issue that we have to keep many useless macro definitions in <acpi/platform/aclinux.h> or <asm/acpi.h>. Such conditions include: COMPILER_DEPENDENT_UINT64 COMPILER_DEPENDENT_INT64 ACPI_INLINE ACPI_SYSTEM_XFACE ACPI_EXTERNAL_XFACE ACPI_INTERNAL_XFACE ACPI_INTERNAL_VAR_XFACE ACPI_MUTEX_TYPE DEBUGGER_THREADING ACPI_ACQUIRE_GLOBAL_LOCK ACPI_RELEASE_GLOBAL_LOCK ACPI_FLUSH_CPU_CACHE They have default implementations in <include/acpi/platform/acenv.h> while Linux need to keep a copy in <asm/acpi.h> to avoid build errors. This patch introduces <acpi/platform/aclinuxex.h> to fix this issue by splitting conditions and declarations (most of them are inline functions) into 2 header files so that the wrong inclusion of <acpi/actypes.h> can be removed from <acpi/platform/aclinux.h>. This patch also removes old ACPI_NATIVE_INTERFACE_HEADER mechanism which is not preferred by Linux and adds the platform/acenvex.h to be the solution to solve this issue.
