Linus Torvalds e6b5be2be4 Driver core patches for 3.19-rc1
Here's the set of driver core patches for 3.19-rc1.
 
 They are dominated by the removal of the .owner field in platform
 drivers.  They touch a lot of files, but they are "simple" changes, just
 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by
 the wireless maintainers as they relied on the debugfs changes.
 
 Everything has been in linux-next for a while.

Linus Torvalds 70e71ca0af Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
Pull networking updates from David Miller:

 1) New offloading infrastructure and example 'rocker' driver for
    offloading of switching and routing to hardware.

    This work was done by a large group of dedicated individuals, not
    limited to: Scott Feldman, Jiri Pirko, Thomas Graf, John Fastabend,
    Jamal Hadi Salim, Andy Gospodarek, Florian Fainelli, Roopa Prabhu

 2) Start making the networking operate on IOV iterators instead of
    modifying iov objects in-situ during transfers.  Thanks to Al Viro
    and Herbert Xu.

 3) A set of new netlink interfaces for the TIPC stack, from Richard
    Alpe.

 4) Remove unnecessary looping during ipv6 routing lookups, from Martin
    KaFai Lau.

 5) Add PAUSE frame generation support to gianfar driver, from Matei
    Pavaluca.

 6) Allow for larger reordering levels in TCP, which are easily
    achievable in the real world right now, from Eric Dumazet.

 7) Add a variable of napi_schedule that doesn't need to disable cpu
    interrupts, from Eric Dumazet.

 8) Use a doubly linked list to optimize neigh_parms_release(), from
    Nicolas Dichtel.

 9) Various enhancements to the kernel BPF verifier, and allow eBPF
    programs to actually be attached to sockets.  From Alexei
    Starovoitov.

10) Support TSO/LSO in sunvnet driver, from David L Stevens.

11) Allow controlling ECN usage via routing metrics, from Florian
    Westphal.

12) Remote checksum offload, from Tom Herbert.

13) Add split-header receive, BQL, and xmit_more support to amd-xgbe
    driver, from Thomas Lendacky.

14) Add MPLS support to openvswitch, from Simon Horman.

15) Support wildcard tunnel endpoints in ipv6 tunnels, from Steffen
    Klassert.

16) Do gro flushes on a per-device basis using a timer, from Eric
    Dumazet.  This tries to resolve the conflicting goals between the
    desired handling of bulk vs.  RPC-like traffic.

17) Allow userspace to ask for the CPU upon what a packet was
    received/steered, via SO_INCOMING_CPU.  From Eric Dumazet.

18) Limit GSO packets to half the current congestion window, from Eric
    Dumazet.

19) Add a generic helper so that all drivers set their RSS keys in a
    consistent way, from Eric Dumazet.

20) Add xmit_more support to enic driver, from Govindarajulu
    Varadarajan.

21) Add VLAN packet scheduler action, from Jiri Pirko.

22) Support configurable RSS hash functions via ethtool, from Eyal
    Perry.

Dan Carpenter 0448d38c1e usb: gadget: f_hid: fix error handling in ghid_setup()
There were a two issues here.

1) We returned PTR_ERR(NULL) which means success if class_create()
   failed.
2) If alloc_chrdev_region() failed then we should clean up before
   returning.

Also kernel style is to have "error handling" as opposed to "success
handling".  In the original code checking for "if (!status) " is
confusing and this bad style is what lead to bug #2.

Kyösti Mälkki 6876d58f2f usb: gadget: dbgp: Fix endpoint config after USB disconnect
SET_FEATURE request with DEBUG_MODE only worked the first time after module
initialisation. Per the USB 2.0 debug device specification, said request
is to be treated as if it were a SET_CONFIGURATION request, i.e. endpoint
must be re-configured.

As configure_endpoints() may now get called multiple times, move it outside
__init and move serial_alloc_tty() call into __init.

Code has assumption that endpoint mapping remains unchanged with consecutive
calls of configure_endpoints().

Andrzej Pietrasiewicz cb38253605 usb: gadget: f_hid: convert to new function interface with backward compatibility
Converting hid to the new function interface requires converting
the USB hid's function code and its users.

This patch converts the f_hid.c to the new function interface.

The file can now be compiled into a separate usb_f_hid.ko module.

The old function interface is provided by means of a preprocessor
conditional directives. After all users are converted, the old interface
can be removed.

So far platform driver has been unregistered first,
so just after that the usb composite is still available,
but there is no hid data any more.

Reverse the order so that first the usb composite becomes
unavailable and second the hid data goes away.
