Christoph Hellwig 1b265da7ea virt: acrn: stop using follow_pfn 
Patch series "remove follow_pfn".

This series open codes follow_pfn in the only remaining caller, although
the code there remains questionable.  It then also moves follow_phys into
the only user and simplifies it a bit.


This patch (of 3):

Switch from follow_pfn to follow_pte so that we can get rid of follow_pfn.
Note that this doesn't fix any of the pre-existing raciness and lack of
permission checking in the code.
