Merge branch 'splice-net-handle-msg_splice_pages-in-chelsio-tls'

David Howells says:

====================
splice, net: Handle MSG_SPLICE_PAGES in Chelsio-TLS

Here are patches to make Chelsio-TLS handle the MSG_SPLICE_PAGES internal
sendmsg flag.  MSG_SPLICE_PAGES is an internal hint that tells the protocol
that it should splice the pages supplied if it can.  Its sendpage
implementation is then turned into a wrapper around that.
