Current vfio-pci implementation disallows to mmap
sub-page(size < PAGE_SIZE) MMIO BARs because these BARs' mmio

And patches realted to kexec/kdump should be CCed to Andrew, he usually

On most platforms, there is only one device controller available.
In this case, we desn't care the UDC's name. So let's ignore the
name by setting 'UDC' to 'any'. And also we can change UDC name
at any time if it is not binded (no need set to "" first).
