A lot of changes on acpi driver code.
- The "Osd*" stuff went away from acpi driver code, use the bus_space functions directly instead. - Fix minor english bugs. acpi_registers_input -> acpi_register_input acpi_registers_output -> acpi_register_output - Remove all magic numbers for the sleeping states. We now have #defines for these. - NULL is treated the same as the return from aml_get_rootname in aml_find_from_namespace(). Suggested by: msmith Thanks mike!
