[Linux-ia64] ia64 patch for ACPI 20020503 release

[Matthew Wilcox <willy@fc.hp.com>]

I need to apply this patch in order to get the 20020503 drop working on
ia64.  Should still be required for the 20020517 drop.  Note that this
is versus David's 2.4.18-020508 release which includes ACPI CA 20020329.
