The i915.enable_ppgtt option depends upon the state of
i915.enable_execlists option - so we need to sanitize execlists first.

For legacy ringbuffer mode, we need the new ordered breadcrumb emission
tried and tested on execlists in order to avoid the dreaded "missed
interrupt" syndrome. A secondary advantage of the execlists method is
that it writes to an arbitrary address, useful if one wants to write a
breadcrumb elsewhere.
This fix is taken from commit 7c17d377374dd (drm/i915: Use ordered seqno
write interrupt generation on gen8+ execlists).

The batadv_neigh_node was specific to a batadv_hardif_neigh_node and held
an implicit reference to it. But this reference was never stored in form of
a pointer in the batadv_neigh_node itself. Instead
batadv_neigh_node_release depends on a consistent state of
hard_iface->neigh_list and that batadv_hardif_neigh_get always returns the
batadv_hardif_neigh_node object which it has a reference for. But
batadv_hardif_neigh_get cannot guarantee that because it is working only
with rcu_read_lock on this list. It can therefore happen that a neigh_addr
is in this list twice or that batadv_hardif_neigh_get cannot find the
batadv_hardif_neigh_node for an neigh_addr due to some other list
operations taking place at the same time.
Instead add a batadv_hardif_neigh_node pointer directly in
batadv_neigh_node which will be used for the reference counter decremented
on release of batadv_neigh_node.

At the moment there is no explicit reactivation of an hard-interface
upon NETDEV_UP event. In case of B.A.T.M.A.N. IV the interface is
reactivated as soon as the next OGM is scheduled for sending, but this
mechanism does not work with B.A.T.M.A.N. V. The latter does not rely
on the same scheduling mechanism as its predecessor and for this reason
the hard-interface remains deactivated forever after being brought down
once.
This patch fixes the reactivation mechanism by adding a new routing API
which explicitly allows each algorithm to perform any needed operation
upon interface re-activation.
Such API is optional and is implemented by B.A.T.M.A.N. V only and it
just takes care of setting the iface status to ACTIVE

Allocation of a frame buffer memory in a special memory region
allows bypassing of so-called IO Coherency aperture
which is typically set as a range 0x8z-0xAz.
I.e. all data traffic to PGU bypasses IO Coherency block
and saves its bandwidth for other peripherals.
Even though for AXS101 (which sorts ARC770 CPU) IOC is not
an option for a sake of keeping one DT description for the
base-board (axs10x_mb.dtsi) we're still defining reserved
memory location in the very end of DDR.

Now when ARC supports reserved memory areas and
per-device coherent DMA allocations we may switch ARC PGU
to use of those dedicated areas.
One of the benefits we may move frame-buffer area out
from IO Coherency aperture and so significantly
reduce IOC utilization allowing less demanding
peripherals to use all perks of IOC.

Allwinner DRM driver for 4.7
This pull request introduces the sun4i driver, meant to be used on the
older Allwinner SoCs (A10, A13, A20, A23, A31 and A33).
It currently supports only the A13, which has one of the simplest video
pipeline. Support for other video components and SoCs will be added
eventually.
It supports only a RGB or composite output. It doesn't do HDMI, VGA, LVDS
or power management yet, but that will come in time as well.

"Usually we get a big collection of fixes for ASoC once during rc. And
this is it.
At this time, most of fixes are about Intel Skylake ASoC driver, which
is a new and still on-going development. Along with it, a slight
large LOC is seen in legacy HD-audio driver, but it's merely a code
move to the upper layer.
Other than that, the rest are small or trivial fixes to various
drivers, in addition to an ASoC dapm debugfs code fix"

Do not bail out from depot_save_stack() if the stack trace has zero hash.
Initially depot_save_stack() silently dropped stack traces with zero
hashes, however there's actually no point in reserving this zero value.

The change fixes improper check for a returned error value by
class_create() function, which on error returns ERR_PTR() value, thus the
original check always results in a dead code on error path.

get_hwpoison_page() must recheck relation between head and tail pages.
n-horiguchi said: without this recheck, the race causes kernel to pin an
irrelevant page, and finally makes kernel crash for refcount mismatch.

Profiling 'if' statements in __sanitizer_cov_trace_pc() leads to
