3.2.70-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Lv Zheng <lv.zh...@intel.com>
commit 85e014b4304626972bff42249556748ad3fcf812 upstream.
commit f254e3c57b9d952e987502aefa0804c177dd2503 upstream.
ACPICA commit 7d9fd64397d7c38899d3dc497525f6e6b044e0e3
OSPMs like Linux expect an acpi_physical_address returning value from
acpi_find_root_pointer(). This triggers warnings if sizeof (acpi_size) doesn't
equal to sizeof (acpi_physical_address):
drivers/acpi/osl.c:275:3: warning: passing argument 1 of
'acpi_find_root_pointer' from incompatible pointer type [enabled by default]
In file included from include/acpi/acpi.h:64:0,
from include/linux/acpi.h:36,
from drivers/acpi/osl.c:41:
include/acpi/acpixf.h:433:1: note: expected 'acpi_size *' but argument is of
type 'acpi_physical_address *'
This patch corrects acpi_find_root_pointer().
