Hello!
Here is my problem. When initing kernel allocatest ranges for ioports some "random" style.
#cat /proc/pci
Bus 2, device 13, function 0:
Class ff00: PCI device 4953:4d50 (rev 1).

As you can see regions of device hashed. Why? Why they arent one-by-one to make possible
use one base pointer to device and works with ports using single shift? May be I can use some tricks?
Please advice.
