[PATCH v4 1/5] ACPICA: Namespace: Fix a regression that MLC support triggers dead lock in dynamic table loading

The new MLC approach invokes MLC per-table basis. But the dynamic loading support of this is incorrect because of the lock order: acpi_ns_evaluate acpi_ex_enter_intperter acpi_ns_load_table (triggered by Load opcode) acpi_ns_exec_module_code_list acpi_ex_enter_intperter The
