From a94e88cdd8057fe8ea84bbb6d9a89a823c7bc49b Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Fri, 4 Apr 2014 12:39:11 +0800 Subject: ACPICA: Tables: Avoid SSDT installation with acpi_gbl_disable_ssdt_table_load. It is reported that when acpi_gbl_disable_ssdt_table_load is specified, user still can see it installed into /sys/firmware/acpi/tables on Linux boxes. This is because the option only stops table "loading", but doesn't stop table "installing", thus it is still in the acpi_gbl_root_table_list. With previous cleanups, it is possible to prevent SSDT installations to make it not such confusing. The global variable is also renamed. Lv Zheng.
