[PATCH] PCI: fix problems with MSI-X on ia64

Browse source

Use "unsigned long" when dealing with PCI resources.
The BAR Indicator Register (BIR) can be a 64-bit value
or the resource could be a 64-bit host physical address.

Enables ib_mthca and cciss drivers to use MSI-X on ia64 HW.
Problem showed up now because of new system firmware on one platform.
Symptom will either be memory corruption or MCA.

Second part of this patch deals with "useless" code.
We walk through the steps to find the phys_addr and then
don't use the result. I suspect the intent was to zero
out the respective MSI-X entry but I'm not sure at the moment.
Delete the code inside the #if 0/#endif if it's really
not needed.
