ACPICA: Tables: Add new table events indicating table installation/uninstallation
ACPICA commit ed6a5fbc694f3a27d93014391aa9a6f6fe490461
This patch adds 2 new table events to indicate table
installation/uninstallation.
Currently, as ACPICA never uninstalls tables, this patch thus only adds
table handler invocation for the table installation event. Lv Zheng.
The 2 events are to be used to fix a sysfs table handling issue related to
LoadTable opcode (see Link # [1] below). The actual sysfs fixing code is
not included, the sysfs fixes will be sent as separate patches.
