Subject: [PATCH v3 0/4] ACPICA: Cleanups for <acpi/platform/acenv.h> and <acpi/platform/aclinux.h>.

This patch series cleans up <acpi/platform/acenv.h> and
<acpi/platform/aclinux.h>.  it also fixes some mis-ordered inclusions for
Linux resident ACPICA.

There is no real issue in the Linux kernel, but this can help to cleanup
the code so that (benefits):
1. Redundant environment definitions can be removed from <asm/acpi.h> and
   <acpi/platform/aclinux.h>.
2. Lift a burden off the ACPICA release automation - copying default ACPICA
   environment setting to all <asm/acpi.h> file each time a new environment
   is introduced just in order to avoid build errors.
3. The wrong <acpi/actypes.h> inclusion can be removed from
   <acpi/platform/aclinux.h>.
4. Using ACPICA defined types in <asm/acpi.h> is possible.
5. Using "static inline" to define ACPICA OSL functions is still possible
   and won't cause build errors any longer.
6. All non back ported prototypes are collected in a single file.

The patch set has passed the following build/boot tests.
Build tests are performed as follows:
1. i386 + default + COFNIG_ACPI=y
2. i386 + default + COFNIG_ACPI=n
3. x86_64 + default + COFNIG_ACPI=y
4. x86_64 + default + COFNIG_ACPI=n
Boot tests are performed as follows:
1. i386 + default + COFNIG_ACPI=y
2. x86_64 + default + COFNIG_ACPI=y
Where:
1. i386: machine named as "Dell Inspiron Mini 1010"
2. x86_64: machine named as "HP Compaq 8200 Elite SFF PC"
3. default: kernel configuration with following items enabled:
   All hardware drivers related to the machines of i386/x86_64
   All drivers/acpi configurations
   All platform drivers
   All ACPI drivers
   4 DRM drivers that implement ACPI opregion
   All buses with ACPI bindings
   All cpufreq configurations
   All xen configurations
   All ACPI table drivers

Lv Zheng (4):
  ACPICA: Linux headers: Remove ACPI_PREEMPTION_POINT() due to no
    usages.
  ACPICA: Linux headers: Add <acpi/platform/aclinuxex.h> to remove
    mis-ordered inclusion of <acpi/actypes.h> from
    <acpi/platform/aclinux.h>.
  ACPICA: Linux headers: Add <asm/acenv.h> to remove mis-ordered
    inclusion of <asm/acpi.h> from <acpi/platform/aclinux.h>.
  ACPICA: Cleanup redudant definitions that already have defaults in
    <acpi/platform/acenv.h>.
