Subject[PATCH] PNPACPI: fix types when decoding ACPI resources [resend]
Date
Any objections to the patch below?  I posted it last Wednesday,
but haven't heard anything. Once we have this fix, 8250_pnp
should have sufficient functionality that we can get rid of
8250_acpi.



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.
