Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
1) Socket addresses returned in the error queue need to be fully
initialized before being passed on to userspace, fix from Willem de
Bruijn.
2) Interrupt handling fixes to davinci_emac driver from Tony Lindgren.
3) Fix races between receive packet steering and cpu hotplug, from Eric
Dumazet.
4) Allowing netlink sockets to subscribe to unknown multicast groups
leads to crashes, don't allow it. From Johannes Berg.
5) One to many socket races in SCTP fixed by Daniel Borkmann.
6) Put in a guard against the mis-use of ipv6 atomic fragments, from
Hagen Paul Pfeifer.
7) Fix promisc mode and ethtool crashes in sh_eth driver, from Ben
Hutchings.
8) NULL deref and double kfree fix in sxgbe driver from Girish K.S and
Byungho An.
9) cfg80211 deadlock fix from Arik Nemtsov.

The /sys/class/mei/meiN directory is created for
each probed mei device
+What: /sys/class/mei/meiN/fw_status
+Date: Nov 2014
+KernelVersion: 3.19
+Contact: Tomas Winkler <tomas.winkler@intel.com>
+Description: Display fw status registers content
+
+ The ME FW writes its status information into fw status
+ registers for BIOS and OS to monitor fw health.
+
+ The register contains running state, power management
+ state, error codes, and others. The way the registers
+ are decoded depends on PCH or SoC generation.
+ Also number of registers varies between 1 and 6
+ depending on generation.
