Summary
pci_iounmap(): Fix MMIO mapping leak
Details

In the Linux kernel, the following vulnerability has been resolved:

pci_iounmap(): Fix MMIO mapping leak

The #ifdef ARCHHASGENERICIOPORTMAP accidentally also guards iounmap(), which means MMIO mappings are leaked.

Move the guard so we call iounmap() for MMIO mappings.
