| |
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.
