[PATCH 03/31] ACPICA: Unix: Cleanup to use ACPI_TO_INTEGER() to calc page offset.

From: Lv Zheng
Date: Sun Apr 12 2015 - 23:56:50 EST


ACPICA commit 9e2d8180f4d5e61949b17513bae8aff6412f62dd

The offset calculation needn't convert a pointer to a special integer type.
So this patch uses ACPI_TO_INTEGER() instead.

This patch only affects acpidump tool.
