Originally AML table sanity check is only done for Load opcode, as
acpi_tb_compare_tables() is only invoked in
acpi_tb_install_standard_table(). While LoadTable opcode cannot be covered
as it directly invokes acpi_tb_load_table() without invoking
acpi_tb_install_standard_table(). Furthermore, standard table load also
cannot be covered as acpi_ns_load_table() is invoked instead of
acpi_tb_install_standard_table() and acpi_tb_load_table().
So it becomes a problem if a duplicate table is in RSDT/XSDT, there is no
such check implemented for static load tables and LoadTable opcode.
This patchset combines code paths (in return reduces some redundant code
blocks and enhances checks/locks) so that duplicate table detection can be
applied to all cases.
