You're absolutely right.  I was just based off a Linus tree, non -mm,
and didn't notice that your patch conflicted.  How about the following
(based on 2.6.13-rc4-mm1)?  I moved the acpi_register_gsi() into
pnpacpi_parse_allocated_irqresource(), which I think is nice because
the test for failure is right next to the call.



PNPACPI: fix types when decoding ACPI resources

Use types that match the ACPI resource structures.  Previously
the u64 value from an RSTYPE_ADDRESS64 was passed as an int,
which corrupts the value.

This is one of the things that prevents 8250_pnp from working
on HP ia64 boxes.  After 8250_pnp works, we will be able to
remove 8250_acpi.c.
