- Move all register I/O into acpi_io.c - Move event handling into acpi_event.c - Reorganise headers into acpivar/acpireg/acpiio - Move find-RSDT and find-ACPI-owned-memory into acpi_machdep - Allocate all resources (except those detailed only by AML) as real resources. Add infrastructure that will make adding resource support to AML code easy. - Remove all ACPI #ifdefs in non-ACPI code - Removed unnecessary includes - Minor style and commenting fixes Reviewed by: iwasaki
