Before the ax25 stack calls dev_queue_xmit it always calls
ax25_type_trans which sets skb->protocol to ETH_P_AX25.
Which means that by looking at the protocol type it is possible to
detect IP packets that have not been munged by the ax25 stack in
ndo_start_xmit and call a function to munge them.
Rename ax25_neigh_xmit to ax25_ip_xmit and tweak the return type and
value to be appropriate for an ndo_start_xmit function.
Update all of the ax25 devices to test the protocol type for ETH_P_IP
and return ax25_ip_xmit as the first thing they do. This preserves
the existing semantics of IP packet processing, but the timing will be
a little different as the IP packets now pass through the qdisc layer
before reaching the ax25 ip packet processing.
Remove the now unnecessary ax25 neighbour table operations.

Set actions consist of a regular OVS_KEY_ATTR_* attribute nested inside
of a OVS_ACTION_ATTR_SET action attribute. When converting masked actions
back to regular set actions, the inner attribute length was not changed,
ie, double the length being serialized. This patch fixes the bug.

Commit 6ce29b0e2a04 ("gianfar: Avoid unnecessary reg accesses in adjust_link()")
eliminates unnecessary calls to adjust_link for phy devices which don't support
interrupts and need polling. As part of that work, the 'new_state' local flag,
which was used to reduce logging noise on the console, was eliminated.
Unfortunately, that means that a 'Link is Down' log message will now be
issued continuously if a link is configured as UP, the link state is down,
and the associated phy requires polling. This occurs because priv->oldduplex
is -1 in this case, which always differs from phydev->duplex. In addition,
phydev->speed may also differ from priv->oldspeed. gfar_update_link_state()
is therefore called each time a phy is polled, even if the link state did not
change.

nfs_vm_page_mkwrite() should wait until the page cache invalidation
is finished. This is the second patch in a 2 patch series to deprecate
the NFS client's reliance on nfs_release_page() in the context of
nfs_invalidate_mapping().

When invalidating the page cache for a regular file, we want to first
sync all dirty data to disk and then call invalidate_inode_pages2().
The latter relies on nfs_launder_page() and nfs_release_page() to deal
respectively with dirty pages, and unstable written pages.
When commit 9590544694bec ("NFS: avoid deadlocks with loop-back mounted
NFS filesystems.") changed the behaviour of nfs_release_page(), then it
made it possible for invalidate_inode_pages2() to fail with an EBUSY.
Unfortunately, that error is then propagated back to read().
Let's therefore work around the problem for now by protecting the call
to sync the data and invalidate_inode_pages2() so that they are atomic
w.r.t. the addition of new writes.
Later on, we can revisit whether or not we still need nfs_launder_page()
and nfs_release_page().

This is a tricky story of the new atomic state handling and the legacy
code fighting over each another. The bug at hand is an underrun of the
framebuffer reference with subsequent hilarity caused by the load
detect code. Which is peculiar since the the exact same code works
fine as the implementation of the legacy setcrtc ioctl.
Let's look at the ingredients:
- Currently our code is a crazy mix of legacy modeset interfaces to
set the parameters and half-baked atomic state tracking underneath.
While this transition is going we're using the transitional plane
helpers to update the atomic side (drm_plane_helper_disable/update
and friends), i.e. plane->state->fb. Since the state structure owns
the fb those functions take care of that themselves.
The legacy state (specifically crtc->primary->fb) is still managed
by the old code (and mostly by the drm core), with the fb reference
counting done by callers (core drm for the ioctl or the i915 load
detect code). The relevant commit is
commit ea2c67bb4affa84080c616920f3899f123786e56

drm/i915: Move to atomic plane helpers (v9)
- drm_plane_helper_disable has special code to handle multiple calls
in a row - it checks plane->crtc == NULL and bails out. This is to
match the proper atomic implementation which needs the crtc to get
at the implied locking context atomic updates always need. See
commit acf24a395c5a9290189b080383564437101d411c

drm/plane-helper: transitional atomic plane helpers
- The universal plane code split out the implicit primary plane from
the CRTC into it's own full-blown drm_plane object. As part of that
the setcrtc ioctl (which updated both the crtc mode and primary
plane) learned to set crtc->primary->crtc on modeset to make sure
the plane->crtc assignments statate up to date in

drm: Add drm_crtc_init_with_planes() (v2)
Unfortunately we've forgotten to update the load detect code. Which
wasn't a problem since the load detect modeset is temporary and
always undone before we drop the locks.
- Finally there is a organically grown history (i.e. don't ask) around
who sets the legacy plane->fb for the various driver entry points.
Originally updating that was the drivers duty, but for almost all
places we've moved that (plus updating the refcounts) into the core.
Again the exception is the load detect code.
Taking all together the following happens:
- The load detect code doesn't set crtc->primary->crtc. This is only
really an issue on crtcs never before used or when userspace
explicitly disabled the primary plane.
- The plane helper glue code short-circuits because of that and leaves
a non-NULL fb behind in plane->state->fb and plane->fb. The state
fb isn't a real problem (it's properly refcounted on its own), it's
just the canary.
- Load detect code drops the reference for that fb, but doesn't set
plane->fb = NULL. This is ok since it's still living in that old
world where drivers had to clear the pointer but the core/callers
handled the refcounting.
- On the next modeset the drm core notices plane->fb and takes care of
refcounting it properly by doing another unref. This drops the
refcount to zero, leaving state->plane now pointing at freed memory.
- intel_plane_duplicate_state still assume it owns a reference to that
very state->fb and bad things start to happen.
Fix this all by applying the same duct-tape as for the legacy setcrtc
ioctl code and set crtc->primary->crtc properly.
