Toke Høiland-Jørgensen 0d070be560 xdp: register system page pool as an XDP memory model ...

[ Upstream commit e77d9aee95 ]

To make the system page pool usable as a source for allocating XDP
frames, we need to register it with xdp_reg_mem_model(), so that page
return works correctly. This is done in preparation for using the system
page_pool to convert XDP_PASS XSk frames to skbs; for the same reason,
make the per-cpu variable non-static so we can access it from other
source files as well (but w/o exporting).
