Anshuman Khandual 36d6cb73d5 mm/dev_pfn: exclude MEMORY_DEVICE_PRIVATE while computing virtual address 
The presence of struct page does not guarantee linear mapping for the pfn
physical range.  Device private memory which is non-coherent is excluded
from linear mapping during devm_memremap_pages() though they will still
have struct page coverage.

Change pfn_t_to_virt() to just check for device private memory before
giving out virtual address for a given pfn.

pfn_t_to_virt() actually has no callers.  Let's fix it for the 5.2 kernel
and remove it in 5.3.
