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.
