      net: remove netdev_alloc_page and use __GFP_COLD · 1f2149c1
      由 Eric Dumazet 提交于 
      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)

      Add appropriate <linux/prefetch.h> include for prefetch users · 70c71606
      由 Paul Gortmaker 提交于 
      After discovering that wide use of prefetch on modern CPUs
could be a net loss instead of a win, net drivers which were
relying on the implicit inclusion of prefetch.h via the list
headers showed up in the resulting cleanup fallout.  Give
them an explicit include via the following $0.02 script.
