SRU Justification

    Impact:
       The upstream process for stable tree updates is quite similar
       in scope to the Ubuntu SRU process, e.g., each patch has to
       demonstrably fix a bug, and each patch is vetted by upstream
       by originating either directly from a mainline/stable Linux tree or
       a minimally backported form of that patch. The following upstream
       stable patches should be included in the Ubuntu kernel:

       4.4.174 upstream stable release
       from git://git.kernel.org/

            
Linux 4.4.174
rcu: Force boolean subscript for expedited stall warnings
net: ipv4: do not handle duplicate fragments as overlapping
net: fix pskb_trim_rcsum_slow() with odd trim offset
inet: frags: better deal with smp races
ipv4: frags: precedence bug in ip_expire()
ip: frags: fix crash in ip_do_fragment()
ip: process in-order fragments efficiently
ip: add helpers to process in-order fragments faster.
ip: use rb trees for IP frag queue.
net: pskb_trim_rcsum() and CHECKSUM_COMPLETE are friends
ipv6: defrag: drop non-last frags smaller than min mtu
net: modify skb_rbtree_purge to return the truesize of all purged skbs.
ip: discard IPv4 datagrams with overlapping segments.
inet: frags: fix ip6frag_low_thresh boundary
inet: frags: get rid of ipfrag_skb_cb/FRAG_CB
inet: frags: reorganize struct netns_frags
rhashtable: reorganize struct rhashtable layout
ipv6: frags: rewrite ip6_expire_frag_queue()
inet: frags: do not clone skb in ip_expire()
inet: frags: break the 2GB limit for frags storage
inet: frags: remove inet_frag_maybe_warn_overflow()
inet: frags: get rif of inet_frag_evicting()
inet: frags: remove some helpers
ipfrag: really prevent allocation on netns exit
net: ieee802154: 6lowpan: fix frag reassembly
inet: frags: use rhashtables for reassembly units
rhashtable: add schedule points
rhashtable: Add rhashtable_lookup()
rhashtable: add rhashtable_lookup_get_insert_key()
inet: frags: refactor lowpan_net_frag_init()
inet: frags: refactor ipv6_frag_init()
inet: frags: refactor ipfrag_init()
inet: frags: add a pointer to struct netns_frags
inet: frags: change inet_frags_init_net() return value

Compile-tested all supported architectures.
