Vivek Kasireddy 7d79cd7844 udmabuf: use vmf_insert_pfn and VM_PFNMAP for handling mmap 
Add VM_PFNMAP to vm_flags in the mmap handler to ensure that the mappings
would be managed without using struct page.

And, in the vm_fault handler, use vmf_insert_pfn to share the page's pfn
to userspace instead of directly sharing the page (via struct page *).
