net: splice: avoid high order page splitting
[ Upstream commit 82bda6195615891181115f579a480aa5001ce7e9 ]
splice() can handle pages of any order, but network code tries hard to
split them in PAGE_SIZE units. Not quite successfully anyway, as
__splice_segment() assumed poff < PAGE_SIZE. This is true for
the skb->data part, not necessarily for the fragments.
This patch removes this logic to give the pages as they are in the skb.
