net: remove netdev_alloc_page and use __GFP_COLD
Given we dont use anymore the struct net_device *dev argument, and this interface brings litle benefit, remove netdev_{alloc|free}_page(), to debloat include/linux/skbuff.h a bit. (Some drivers used a mix of these interfaces and alloc_pages()) When allocating a page given to device for DMA transfer (device to memory), it makes sense to use a cold one (__GFP_COLD) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> CC: Jeff Kirsher <jeffrey.t.kirsher@intel.com> CC: Dimitris Michailidis <dm@chelsio.com> Signed-off-by: David S.
