911883759f Merge branch 'stable-3.18' of git://git.infradead.org/users/pcmoore/audit
Pull audit fixes from Paul Moore:
 "After he sent the initial audit pull request for 3.18, Eric asked me
  to take over the management of the audit tree, hence this pull request
  to fix a couple of problems with audit.

  As you can see below, the changes are minimal: adding some whitespace
  to a string so userspace parses it correctly, and fixing a problem
  with audit's usage of fsnotify that was causing audit watch rules to
  be lost.  Neither of these patches were very controversial on the
  mailing lists and they fix real problems, getting them into 3.18 would
  be a good thing"

. stable fix for a dm-cache related bug in dm-btree walking code that
   results from using very large fast device (e.g. 4T) with a very small
   cache blocksize (e.g. 32K) -- this is a very uncommon configuration
 
 . a couple fixes for dm-raid (one for stable and the other addresses a
   crash in 3.18-rc1 code)
 
 . stable fix for dm-thinp that addresses a very rare dm-bufio bug having
   to do with memory reclaimation (via shrinker) when using dm-thinp
   ontop of loopback devices

3542aed748 ALSA: hda - Add mute LED control for Lenovo Ideapad Z560
Lenovo Ideapad Z560 has a mute LED that is controlled via EAPD pin
0x1b on CX20585 codec.  (EAPD bit on corresponds to mute LED on.)
The machine doesn't need other EAPD, so the fixup concentrates on
controlling EAPD 0x1b following the vmaster state (but inversely).

65eca3a202 virtio_console: move early VQ enablement
Commit f5866db6 (virtio_console: enable VQs early) tried to make
sure that DRIVER_OK was set when virtio_console started using its
virtqueues. Doing this in add_port(), however, means that we try
to set DRIVER_OK again when when a port is dynamically added after
the probe function is done.

Let's move virtio_device_ready() to the probe function just before
trying to use the virtqueues instead. This is fine as nothing can
fail inbetween.

9dfa9a27b6 net: systemport: fix tx work done in TX napi poll
With commit d75b1ade56 ("net: less interrupt masking in NAPI") napi
repoll is done only when work_done == budget. bcm_sysport_tx_poll()
always returns 0 whether or not we completed the poll quantum.

Fix this by returning either 0 when we did complete the TX ring reclaim,
or budget to trigger a repoll.

15e5cda9e6 Rabin Vincent found a way that tracing could cause an infinite loop
in the kernel. The splice logic wants a full page from the ring buffer
 but the ring_buffer_wait() returns when there's any data in the ring buffer.
 The splice code would then continue the loop waiting for a full page.
 But if a full page never happens, the splice code will never sleep and
 just continue to loop.
 
 There's another case that Rabin fixed that could loop if there's no memory
 and kmalloc() constantly returns NULL.

6251edd932 netlink: Properly unbind in error conditions.
Even if netlink_kernel_cfg::unbind is implemented the unbind() method is
not called, because cfg->unbind is omitted in __netlink_kernel_create().
And fix wrong argument of test_bit() and off by one problem.

At this point, no unbind() method is implemented, so there is no real
issue.

cca04b2854 net: ptp: fix time stamp matching logic for VLAN packets.
Commit ae5c6c6d "ptp: Classify ptp over ip over vlan packets" changed the
code in two drivers that matches time stamps with PTP frames, with the goal
of allowing VLAN tagged PTP packets to receive hardware time stamps.

However, that commit failed to account for the VLAN header when parsing
IPv4 packets. This patch fixes those two drivers to correctly match VLAN
tagged IPv4/UDP PTP messages with their time stamps.

This patch should also be applied to v3.17.

a8c5f90fb5 ip_tunnel: Ops registration for secondary encap (fou, gue)
Instead of calling fou and gue functions directly from ip_tunnel
use ops for these that were previously registered. This patch adds the
logic to add and remove encapsulation operations for ip_tunnel,
and modified fou (and gue) to register with ip_tunnels.

This patch also addresses a circular dependency between ip_tunnel
and fou that was causing link errors when CONFIG_NET_IP_TUNNEL=y
and CONFIG_NET_FOU=m. References to fou an gue have been removed from
ip_tunnel.c
