Quantum 7e58278858 [module] fault in pages one by one for ivshmem devices 
It appears that the PCI BAR memory is slow to access with remap_pfn_range
and that it should instead be faulted in one page at a time.

The commit 5774e21965 implemented the former
behaviour and caused a performance regression in the VM->VM case.

This commit retores the old behaviour, but extends it to support mmaping
the kvmfr device directly, without going through a dmabuf.
