Changes from v2:
      1. Rebase on linux-next as of Jul 29.
      2. Skip 'niov->pp = NULL' when it's allocated using __GFP_ZERO.
      3. Change trivial coding style. (feedbacked by Mina)
      4. Add Co-developed-by, Acked-by, and Reviewed-by properly.
         Thanks to all.

Changes from v1:
      1. Rebase on linux-next.
      2. Initialize net_iov->pp = NULL when allocating net_iov in
         net_devmem_bind_dmabuf() and io_zcrx_create_area().
      3. Use ->pp for net_iov to identify if it's pp rather than
         always consider net_iov as pp.
      4. Add Suggested-by: David Hildenbrand [off-list ref].

That will conflict with "netmem: replace __netmem_clear_lsb() with
netmem_to_nmdesc()", it'll need some coordination.

Indeed.  It'd better work on top of "netmem: replace __netmem_clear_lsb()
with netmem_to_nmdesc()" then.  You said you are going to take the patch.
Please lemme know the progress so that I can track and re-work on this.
