Compile fix for ACPI in 2.4.22/x86-64

[Andi Kleen <ak@muc.de>]

Marcelo unfortunately added an last minute ACPI update that changed
ACPI interfaces and broke x86-64 compilation. I didn't catch it in
time, so 2.4.22 does not compile out of the box for AMD64. 

This patch fixes it.
You'll have to apply it when compiling 2.4.22 for x86-64

----------

Update x86-64 for the ACPI interrupt link changes.
