From a6823e12ca3f79a8c0f8b2d14976ab2152d117e5 Mon Sep 17 00:00:00 2001 From: Alexey Starikovskiy Date: Fri, 2 Feb 2007 19:48:22 +0300 Subject: ACPICA: Fixes for load() operator. Optimized the Load operator in the case where the source operand is an operation region. Simply map the operation region memory, instead of performing a bytewise read.
