Came accross two open coding of for_each_pipe(), might as well use the
macro.

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):

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.

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;
	ioctl(wd_fd, WDIOC_SETOPTIONS, &flags);

	close(wd_fd);

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.

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.

Linus Torvalds
19d2f8e0fb Second round of 9p patches for the 3.11 merge window.
Several of these patches were rebased in order to correct style issues.
 Only stylistic changes were made versus the patches which were in linux-next
 for two weeks.  The rebases have been in linux-next for 3 days and have
 passed my regressions.
 
 The bulk of these are RDMA fixes and improvements.  There's also some
 additions on the extended attributes front to support some additional
 namespaces and a new option for TCP to force allocation of mount requests
 from a priviledged port.
