Subject: [PATCH 3.12 142/142] ACPICA: Utilities: Cleanup to remove useless ACPI_PRINTF/FORMAT_xxx helpers.
From: Lv Zheng <lv.zheng@...el.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 1d0a0b2f6df2bf2643fadc990eb143361eca6ada upstream.
ACPICA commit b60612373a4ef63b64a57c124576d7ddb6d8efb6
For physical addresses, since the address may exceed 32-bit address range
after calculation, we should use 0x%8.8X%8.8X instead of ACPI_PRINTF_UINT
and ACPI_FORMAT_UINT64() instead of
ACPI_FORMAT_NATIVE_UINT()/ACPI_FORMAT_TO_UINT().
This patch also removes above replaced macros as there are no users.
This is a preparation to switch acpi_physical_address to 64-bit on 32-bit
kernel builds.
