Jiaqing Zhao e5d46dcc7d hv: vpci: ignore PCI I/O BAR with non-zero upper 16 bits ... On x86 platform, the upper 16 bit of I/O BAR should be initialized to zero by BIOS. Howerever, some buggy BIOS still programs the upper 16 bits to non-zero, which causes error in check_pt_dev_pio_bars(). Since I/O BAR reprogramming by VM is currently unsupported, this patch ignores such I/O BARs when creating vpci devices to make VM boot.
