Subject: linux-next: build failure after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

net/core/xdp.c: In function 'xdp_return_frame_bulk':
net/core/xdp.c:417:3: error: too few arguments to function '__xdp_return'
  417 |   __xdp_return(xdpf->data, &xdpf->mem, false);
      |   ^~~~~~~~~~~~
net/core/xdp.c:340:13: note: declared here
  340 | static void __xdp_return(void *data, struct xdp_mem_info *mem, bool napi_direct,
      |             ^~~~~~~~~~~~

Caused by commit

  8965398713d8 ("net: xdp: Introduce bulking for xdp tx return path")

interacting with commit

  ed1182dc004d ("xdp: Handle MEM_TYPE_XSK_BUFF_POOL correctly in xdp_return_buff()")

from the bpf tree.

I applied the following merge fix patch.
