From f3d2e7865c816258c699ff965768e46b50d536d3 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Fri, 2 Feb 2007 19:48:18 +0300 Subject: ACPICA: Implement simplified Table Manager The Table Manager component has been completely redesigned and reimplemented. The new design is much simpler, and reduces the overall code and data size of the kernel-resident ACPICA by approximately 5%. Also, it is now possible to obtain the ACPI tables very early during kernel initialization, even before dynamic memory management is initialized.
