Modified Files: src/sys/dev/pci: pci_map.c Log Message: disable I/O or mem decode before probing BAR size. Bar size is probed writing 0xffffffff to the BAR and reading back; but while doing this the decoding address is not guaranteed to be valid and could have side effect. Xen PVH enforces disabling decoding before writing to a BAR.
