Hi Marcelo,

I'd like to try again to get you to merge in the latest ACPI change into
2.4. I know it's a big patch but the identical code has been in 2.5 all
along. BitKeeper has been a big help in allowing me to maintain such a
big patch for so long, but the fact is that getting this in 2.4 would
make my life and other maintainers' lives much easier.

The ACPI code in 2.4 is very old and buggy. Even though the current code
is not flawless, it is much much improved. Its inclusion would not
affect anything at all for people who don't explicitly configure in ACPI
support.

Please let me know what you think. :-)

Thanks -- Regards -- Andy

1) Split blacklist code out into a separate file.

use ACPI

late.

3) PCI IRQ routing

Also included in this changeset is some i386-specific ACPI code, and
