Pull networking updates from David Miller:
"This is a re-do of the net-next pull request for the current merge
window. The only difference from the one I made the other day is that
this has Eliezer's interface renames and the timeout handling changes
made based upon your feedback, as well as a few bug fixes that have
trickeled in.Highlights:
1) Low latency device polling, eliminating the cost of interrupt
handling and context switches. Allows direct polling of a network
device from socket operations, such as recvmsg() and poll().Currently ixgbe, mlx4, and bnx2x support this feature.
Full high level description, performance numbers, and design in
commit 0a4db187a999 ("Merge branch 'll_poll'")From Eliezer Tamir.
2) With the routing cache removed, ip_check_mc_rcu() gets exercised
more than ever before in the case where we have lots of multicast
addresses. Use a hash table instead of a simple linked list, from
Eric Dumazet.3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from
Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski,
Marek Puzyniak, Michal Kazior, and Sujith Manoharan.4) Support reporting the TUN device persist flag to userspace, from
Pavel Emelyanov.5) Allow controlling network device VF link state using netlink, from
Rony Efraim.6) Support GRE tunneling in openvswitch, from Pravin B Shelar.
7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from
Daniel Borkmann and Eric Dumazet.8) Allow controlling of TCP quickack behavior on a per-route basis,
from Cong Wang.9) Several bug fixes and improvements to vxlan from Stephen
Hemminger, Pravin B Shelar, and Mike Rapoport. In particular,
support receiving on multiple UDP ports.10) Major cleanups, particular in the area of debugging and cookie
lifetime handline, to the SCTP protocol code. From Daniel
Borkmann.11) Allow packets to cross network namespaces when traversing tunnel
devices. From Nicolas Dichtel.12) Allow monitoring netlink traffic via AF_PACKET sockets, in a
manner akin to how we monitor real network traffic via ptype_all.
From Daniel Borkmann.13) Several bug fixes and improvements for the new alx device driver,
from Johannes Berg.14) Fix scalability issues in the netem packet scheduler's time queue,
by using an rbtree. From Eric Dumazet.15) Several bug fixes in TCP loss recovery handling, from Yuchung
Cheng.16) Add support for GSO segmentation of MPLS packets, from Simon
Horman.17) Make network notifiers have a real data type for the opaque
pointer that's passed into them. Use this to properly handle
network device flag changes in arp_netdev_event(). From Jiri
Pirko and Timo Teräs.18) Convert several drivers over to module_pci_driver(), from Peter
Huewe.19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a
O(1) calculation instead. From Eric Dumazet.20) Support setting of explicit tunnel peer addresses in ipv6, just
like ipv4. From Nicolas Dichtel.21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet.
22) Prevent a single high rate flow from overruning an individual cpu
during RX packet processing via selective flow shedding. From
Willem de Bruijn.23) Don't use spinlocks in TCP md5 signing fast paths, from Eric
Dumazet.24) Don't just drop GSO packets which are above the TBF scheduler's
burst limit, chop them up so they are in-bounds instead. Also
from Eric Dumazet.25) VLAN offloads are missed when configured on top of a bridge, fix
from Vlad Yasevich.26) Support IPV6 in ping sockets. From Lorenzo Colitti.
27) Receive flow steering targets should be updated at poll() time
too, from David Majnemer.28) Fix several corner case regressions in PMTU/redirect handling due
to the routing cache removal, from Timo Teräs.29) We have to be mindful of ipv4 mapped ipv6 sockets in
upd_v6_push_pending_frames(). From Hannes Frederic Sowa.30) Fix L2TP sequence number handling bugs, from James Chapman."

Concentrate code to modify totalram_pages into the mm core, so the arch
memory initialized code doesn't need to take care of it. With these
changes applied, only following functions from mm core modify global
variable totalram_pages: free_bootmem_late(), free_all_bootmem(),
free_all_bootmem_node(), adjust_managed_page_count().With this patch applied, it will be much more easier for us to keep
totalram_pages and zone->managed_pages in consistence.Signed-off-by: Jiang Liu

Address more review comments from last round of code review.
1) Enhance free_reserved_area() to support poisoning freed memory with
pattern '0'. This could be used to get rid of poison_init_mem()
on ARM64.
2) A previous patch has disabled memory poison for initmem on s390
by mistake, so restore to the original behavior.
3) Remove redundant PAGE_ALIGN() when calling free_reserved_area().Signed-off-by: Jiang Liu

On Ubuntu, where /bin/sh -> dash, "make ARCH=h8300 clean" gives:
printf: 1: $[0x00400000+0x00140000]: expected numeric value
Replace the bash-specific "$[...]" by POSIX "$((..))" for arithmetic

also removed __SYMBOL_NAME(), hidden in a merge conflict resolution.Hence, replace the use of SYMBOL_NAME() and SYMBOL_NAME_LABEL() in h8300
assembler sources by hardcoding the underscore symbol prefix, like other
