Log:
[USETUP]
- Autodetect ACPI like we autodetect a multiprocessor configuration
- This will make the ACPI HAL the default on ACPI-compliant machines while the standard
HAL will continue to be the default on older machines
- Please file bugs for any issues encountered when running in ACPI mode and assign them to
me (I think it's very important to have working ACPI for 0.4.0 so I'd really like
to get everything fixed now)
[TXTSETUP.SIF]
- Add a MP configuration for ACPI HAL
- Slightly modify the names of each HAL configuration
