| Subject | [PATCH 3/5] ACPICA: Tables: Add new table events indicating table installation/uninstallation |

This patch adds 2 new table events to indicate table
installation/uninstallation.
Currently, as ACPICA never uninstalls tables, this patch thus only add
table handler invocation for the table installation event. Lv Zheng.
