ACPI / bus: Adjust ACPI subsystem initialization for new table loading mode (1ef35668) · Commits · 戴 / test

This patch enables the following initialization order for the new table loading mode (which is enabled by setting acpi_gbl_parse_table_as_term_list to TRUE): 1. Install default region handlers (SystemMemory, SystemIo, PciConfig, EmbeddedControl via ECDT) without evaluating _REG; 2. Load the table and execute the module level AML opcodes instantly.
