2.4.23-pre8 ACPI breaks x86_64

[Bernhard Rosenkraenzer]

SSIA - drivers/acpi/bus.c started using acpi_pic_set_level_irq 
unconditionally, and the function doesn't exist on x86_64.

The attached patch _might_ fix it (I don't have the x86_64 manuals and 
can't reboot my x86_64 test box to test myself ATM -- too many people 
working on it ;) )
