Pull networking fixes from David Miller:
 "A quick set of bug fixes after there initial networking merge:

  1) Netlink multicast group storage allocator only was tested with
     nr_groups equal to 1, make it work for other values too.  From
     Matti Vaittinen.

  2) Check build_skb() return value in macb and hip04_eth drivers, from
     Weidong Wang.

  3) Don't leak x25_asy on x25_asy_open() failure.

  4) More DMA map/unmap fixes in 3c59x from Neil Horman.

  5) Don't clobber IP skb control block during GSO segmentation, from
     Konstantin Khlebnikov.

  6) ECN helpers for ipv6 don't fixup the checksum, from Eric Dumazet.

  7) Fix SKB segment utilization estimation in xen-netback, from David
     Vrabel.

  8) Fix lockdep splat in bridge addrlist handling, from Nikolay
     Aleksandrov"

Hisilicon HiP05 PERISUB system controller
Required properties:
- compatible : "hisilicon,hip05-perisubc", "syscon";
- reg : Register address and size
The HiP05 PERISUB system controller is shared by peripheral controllers in
HiP05 Soc to implement some basic configurations. The peripheral
controllers include mdio, ddr, iic, uart, timer and so on.
Example:
/* for HiP05 perisub-ctrl-c system */
peri_c_subctrl: syscon@80000000 {
compatible = "hisilicon,hip05-perisubc", "syscon";
reg = <0x0 0x80000000 0x0 0x10000>;
