[Openpvrsgx-devgroup] [PATCH 2/2] pvrsrv: 1.17: osfunc: Add va_to_pfn()

[Tony Lindgren]

> With commit 0d940a9b270b ("mm/pgtable: allow pte_offset_map[_lock]() to
> fail"), __pte_offset_map_lock() is no longer inlined and not exported
> and using it in loadable modules fails.
> 
> Let's add va_to_pfn() similar to follow_pfn() and drop the pvr specific
> function.

This is only briefly tested, I may have missed something so please review.

Regards,

Tony
