Ok.

The kvm_pfn_t conversion is only needed if the new pfn_t
infrastructure moves forward, and at this point it still needs some
review feedback.
How about this, care to send conversion patches for the rest? ...based on:
https://git.kernel.org/cgit/linux/kernel/git/djbw/nvdimm.git/log/?h=libnvdimm-pending
When/if the new pfn_t bits move forward I'll carry them in the same
pull request through the nvdimm.git tree.
