Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking tree from David Miller:
1) ptp_pch driver build broke during this merge window due to missing
slab.h header, fix from Geery Uytterhoeven.
2) If ipset passes in a bogus hash table size we crash because the size
is not validated properly. Compounding this, gcc-4.7 can miscompile
ipset such that even when the user specifies legitimate parameters
the tool passes in an out-of-range size to the kernel.
Fix from Jozsef Kadlecsik.
3) Users have reported that the netdev watchdog can trigger with pch_gbe
devices, and it turns out this is happening because of races in the
TX path of the driver leading to the transmitter hanging. Fix from
Eric Dumazet, reported and tested by Andy Cress.
4) Novatel USB551L devices match the generic class entries for the cdc
ethernet USB driver, but they don't work because they have generic
descriptors and thus need FLAG_WWAN to function properly.
Add the necessary ID table entry to fix this, from Dan Williams.
5) A recursive locking fix in the USBNET driver added a new problem, in
that packet list traversal is now racy and we can thus access
unlinked SKBs and crash.
Avoid this situation by adding some extra state tracking, from Ming
Lei.
6) The rtlwifi conversion to asynchronous firmware loading is racy, fix
by reordering the probe procedure. From Larry Finger.
Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=43187
7) Fix regressions with bluetooth keyboards by notifying userland
properly when the security level changes, from Gustavo Padovan.
8) Bluetooth needs to make sure device connected events are emitted
before other kinds of events, otherwise userspace will think there is
no baseband link yet and therefore abort the sockets associated with
that connection.

Why: setitimer is not returning -EFAULT if user pointer is NULL. This
violates the spec.
Who: Sasikantha Babu <sasikanth.v19@gmail.com>

+----------------------------

+What: V4L2_CID_HCENTER, V4L2_CID_VCENTER V4L2 controls
+When: 3.7
+Why: The V4L2_CID_VCENTER, V4L2_CID_HCENTER controls have been deprecated
+ for about 4 years and they are not used by any mainline driver.
+ There are newer controls (V4L2_CID_PAN*, V4L2_CID_TILT*) that provide
+ similar functionality.
