From 9187a415fd119c1d89a5ad2fd05513cd43699ebf Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Thu, 31 Oct 2013 09:30:28 +0800 Subject: ACPICA: Add new statistics interface. This patch ports new counters and statistics interface, already implemented in ACPICA upstream, to Linux. That helps to reduce source code differences between Linux and ACPICA upstream.
