Paolo Valente 88d4f419a4 pkt_sched: sch_qfq: remove forward declaration of qfq_update_agg_ts
This patch removes the forward declaration of qfq_update_agg_ts, by moving
the definition of the function above its first call. This patch also
removes a useless forward declaration of qfq_schedule_agg.

Paolo Valente 87f1369d6e pkt_sched: sch_qfq: improve efficiency of make_eligible
In make_eligible, a mask is used to decide which groups must become eligible:
the i-th group becomes eligible only if the i-th bit of the mask (from the
right) is set. The mask is computed by left-shifting a 1 by a given number of
places, and decrementing the result.  The shift is performed on a ULL to avoid
problems in case the number of places to shift is higher than 31.  On a 32-bit
machine, this is more costly than working on an UL. This patch replaces such a
costly operation with two cheaper branches.

The trick is based on the following fact: in case of a shift of at least 32
places, the resulting mask has at least the 32 less significant bits set,
whereas the total number of groups is lower than 32.  As a consequence, in this
case it is enough to just set the 32 less significant bits of the mask with a
cheaper ~0UL. In the other case, the shift can be safely performed on a UL.

Linus Torvalds 6d2fa9e141 Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger:
 "Lots of activity this round on performance improvements in target-core
  while benchmarking the prototype scsi-mq initiator code with
  vhost-scsi fabric ports, along with a number of iscsi/iser-target
  improvements and hardening fixes for exception path cases post v3.10
  merge.

  The highlights include:

   - Make persistent reservations APTPL buffer allocated on-demand, and
     drop per t10_reservation buffer.  (grover)
   - Make virtual LUN=0 a NULLIO device, and skip allocation of NULLIO
     device pages (grover)
   - Add transport_cmd_check_stop write_pending bit to avoid extra
     access of ->t_state_lock is WRITE I/O submission fast-path.  (nab)
   - Drop unnecessary CMD_T_DEV_ACTIVE check from
     transport_lun_remove_cmd to avoid extra access of ->t_state_lock in
     release fast-path.  (nab)
   - Avoid extra t_state_lock access in __target_execute_cmd fast-path
     (nab)
   - Drop unnecessary vhost-scsi wait_for_tasks=true usage +
     ->t_state_lock access in release fast-path.  (nab)
   - Convert vhost-scsi to use modern se_cmd->cmd_kref
     TARGET_SCF_ACK_KREF usage (nab)
   - Add tracepoints for SCSI commands being processed (roland)
   - Refactoring of iscsi-target handling of ISCSI_OP_NOOP +
     ISCSI_OP_TEXT to be transport independent (nab)
   - Add iscsi-target SendTargets=$IQN support for in-band discovery
     (nab)
   - Add iser-target support for in-band discovery (nab + Or)
   - Add iscsi-target demo-mode TPG authentication context support (nab)
   - Fix isert_put_reject payload buffer post (nab)
   - Fix iscsit_add_reject* usage for iser (nab)
   - Fix iscsit_sequence_cmd reject handling for iser (nab)
   - Fix ISCSI_OP_SCSI_TMFUNC handling for iser (nab)
   - Fix session reset bug with RDMA_CM_EVENT_DISCONNECTED (nab)

  The last five iscsi/iser-target items are CC'ed to stable, as they do
  address issues present in v3.10 code.  They are certainly larger than
  I'd like for stable patch set, but are important to ensure proper
  REJECT exception handling in iser-target for 3.10.y"

Viresh Kumar 6e63a3a294 watchdog: delete mpcore_wdt driver
Interrupt request doesn't use the right API: The TWD watchdog uses a per-cpu
interrupt (usually interrupt #30), and the GIC configuration should flag it as
such. With this setup, request_irq() should fail, and the right API is
request_percpu_irq(), together with enable_percpu_irq()/disable_percpu_irq().

Nothing ensures the userspace ioctl() will end-up kicking the watchdog on the
right CPU.

There are no users of this driver since a long time and it makes more sense to
get rid of it as nobody is looking to fix it.

In case somebody wakes up after this has been removed and needs it, please
revert this driver and pick these updates (These were never pushed to mainline):

Alexander Duyck cdbaa0bb26 gso: Update tunnel segmentation to support Tx checksum offload
This change makes it so that the GRE and VXLAN tunnels can make use of Tx
checksum offload support provided by some drivers via the hw_enc_features.
Without this fix enabling GSO means sacrificing Tx checksum offload and
this actually leads to a performance regression as shown below:

            Utilization
            Send
Throughput  local         GSO
10^6bits/s  % S           state
  6276.51   8.39          enabled
  7123.52   8.42          disabled

To resolve this it was necessary to address two items.  First
netif_skb_features needed to be updated so that it would correctly handle
the Trans Ether Bridging protocol without impacting the need to check for
Q-in-Q tagging.  To do this it was necessary to update harmonize_features
so that it used skb_network_protocol instead of just using the outer
protocol.

Second it was necessary to update the GRE and UDP tunnel segmentation
offloads so that they would reset the encapsulation bit and inner header
offsets after the offload was complete.

As a result of this change I have seen the following results on a interface
with Tx checksum enabled for encapsulated frames:

            Utilization
            Send
Throughput  local         GSO
10^6bits/s  % S           state
  7123.52   8.42          disabled
  8321.75   5.43          enabled

v2: Instead of replacing refrence to skb->protocol with
    skb_network_protocol just replace the protocol reference in
    harmonize_features to allow for double VLAN tag checks.

Hector Palacios fcf95670fd watchdog: core: don't try to stop device if not running
A watchdog device may be stopped from userspace using WDIOC_SETOPTIONS
ioctl and flag WDIOS_DISABLECARD. If the device is closed after this
operation, watchdog_release() is called and status bits checked for
stopping it. Besides, if the device has not been unregistered a critical
message "watchdog did not stop!" is printed, although the ioctl may have
successfully stopped it already.

Without the patch a user application sample code like this will successfully
stop the watchdog, but the kernel will output the message
"watchdog did not stop!":

	wd_fd = open("/dev/watchdog", O_RDWR);

	flags = WDIOS_DISABLECARD;

Hannes Frederic Sowa afc154e978 ipv6: fix route selection if kernel is not compiled with CONFIG_IPV6_ROUTER_PREF
This is a follow-up patch to 3630d40067
("ipv6: rt6_check_neigh should successfully verify neigh if no NUD
information are available").

Since the removal of rt->n in rt6_info we can end up with a dst ==
NULL in rt6_check_neigh. In case the kernel is not compiled with
CONFIG_IPV6_ROUTER_PREF we should also select a route with unkown
NUD state but we must not avoid doing round robin selection on routes
with the same target. So introduce and pass down a boolean ``do_rr'' to
indicate when we should update rt->rr_ptr. As soon as no route is valid
we do backtracking and do a lookup on a higher level in the fib trie.

v2:
a) Improved rt6_check_neigh logic (no need to create neighbour there)
   and documented return values.

v3:
a) Introduce enum rt6_nud_state to get rid of the magic numbers
   (thanks to David Miller).
b) Update and shorten commit message a bit to actualy reflect
   the source.

Move spin_lock_init to be called before the spinlocks are used, preventing a lockdep splat.

Pravin B Shelar f89e57c4f5 vxlan: Fix kernel crash on rmmod.
vxlan exit module unregisters vxlan net and then it unregisters
rtnl ops which triggers vxlan_dellink() from __rtnl_kill_links().
vxlan_dellink() deletes vxlan-dev from vxlan_list which has
list-head in vxlan-net-struct but that is already gone due to
net-unregister. That is how we are getting following crash.

Following commit fixes the crash by fixing module exit path.
