[PATCH 0/4] Fix v3.14.41 ARCH=i386 ACPI build warnings

["George G. Davis" <ggdavisiv@gmail.com>]

From: "George G. Davis" <george_davis@mentor.com>

Hello,

The following changes introduced in the recent v3.14.41 update have introduced
build warnings for the ARCH=i386 case:

a26f0f3 ACPICA: Utilities: split IO address types from data type models.
8c56b5e ACPI / scan: Annotate physical_node_lock in acpi_scan_is_offline()


As of v3.14.41, the following new build warnings exist for the `make ARCH=i386
i386_defconfig bzImage` case:

The following upstream commits have been backported to v3.14.41 in order to
resolve the above build warnings:

Lv Zheng (4):
  ACPICA: Tables: Change acpi_find_root_pointer() to use
    acpi_physical_address.
  ACPICA: Utilities: Cleanup to enforce
    ACPI_PHYSADDR_TO_PTR()/ACPI_PTR_TO_PHYSADDR().
  ACPICA: Utilities: Cleanup to convert physical address printing
    formats.
  ACPICA: Utilities: Cleanup to remove useless ACPI_PRINTF/FORMAT_xxx
    helpers.
