[Acpi-checkins] problem wirh PCI Interrupt Link

[<sz...@op...>]

I have ISA sound card, which have been working on irq 5. Kernel ACPI unexpectedly allocated irq 5 for unused and disabled PCI interput link [LINKC]. 
It couse a lot of problems with stability of my linux box, befor I dicovered what was happend.
In /proc/interputs wasn't information about it.
I thing, It is good idea to turned it off (auto allocating irq for disabled and unused PCI interput link [LINK?] ) optionally via kernel command line.
