From a9a41ca37c81d67c4527087c329367f8133b826c Mon Sep 17 00:00:00 2001 From: Mike Smith Date: Tue, 29 May 2001 19:52:32 +0000 Subject: Import the 20010518 Intel ACPI CA release. Note that Intel's directory layout keeps changing, so to reduce repository thrash everything has been moved into a single directory.
