freebsd-nq/sys/dev/acpi/acpivar.h
Mike Smith 96f5284585 More updates to the ACPI code: 
- 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
