"ip route get $daddr iif eth0 from $saddr" causes:
BUG: KASAN: use-after-free in ip_route_input_rcu+0x1535/0x1b50
Call Trace:
ip_route_input_rcu+0x1535/0x1b50

Problem is that inet_rtm_getroute calls either ip_route_input_rcu (if an
iif was provided) or ip_route_output_key_hash_rcu.
But ip_route_input_rcu, unlike ip_route_output_key_hash_rcu, already
associates the dst_entry with the skb. This clears the SKB_DST_NOREF
bit (i.e. skb_dst_drop will release/free the entry while it should not).
Thus only set the dst if we called ip_route_output_key_hash_rcu().
I tested this patch by running:
while true;do ip r get 10.0.1.2;done > /dev/null &
while true;do ip r get 10.0.1.2 iif eth0 from 10.0.1.1;done > /dev/null &
... and saw no crash or memory leak.

drm/i915: Break modeset deadlocks on reset
Because defense-in-depth is good it's good to still have both. Also
note that with the locking change we can now restrict this a lot (old
gpus and special testing only), so this doesn't kill the TDR benefits
on at least anything remotely modern.
And futuremore with a few tricks it should be possible to make a much
more educated guess about whether an atomic commit is stuck waiting on
the gpu (atomic_t counting the pending i915_sw_fence used by the
atomic modeset code should do it), so we can improve this.
But for now just start with something that is guaranteed to recover
faster, for much better CI througput.
This defacto reverts TDR on these platforms, but there's not really a
single commit to specify as the sole offender.
v2: Add a debug message to explain what's going on. We can't DRM_ERROR
because that spams CI. And the timeout based fallback still prints a
DRM_ERROR, in case something goes wrong.
v3: Fix comment layout (Michel)

When switching between contexts using the aliasing_ppgtt, the VM is
shared. We don't need to reload the PD registers unless they are dirty.
Martin Peres reported an issue that looks like corruption between
Haswell context switches, bisecting to commit f9326be5f1 ("drm/i915:
Rearrange switch_context to load the aliasing ppgtt on first use").
Switching between the same mm (the aliasing_ppgtt is used for all
contexts in this case) should be a nop, but appears to trigger some
side-effects in the context switch. However, as we know the switch
is redundant in this case, we can skip it and continue to ignore the
issue until somebody feels strong enough to investigate full-ppgtt on
gen7 again!
Except.. Martin was using full-ppgtt which is not supported as it
doesn't work correctly yet. So whilst the bisect did yield valuable
information about the failures, the fix should not have any user impact
under default settings, with the exception of a slightly lower
throughput on xcs as the VM would always be reloaded.
v2: Also remember to set the legacy_active_context following the switch
on xcs (commit e8a9c58fcd ("drm/i915: Unify active context tracking
between legacy/execlists/guc"))

As we may have just bound the renderstate into the GGTT for execution, we
need to ensure that the GTT TLB are also flushed.
On snb-gt2, this would cause a random GPU hang at the start of a new
context (e.g. boot) and on snb-gt1, it was causing the renderstate batch
to take ~10s. It was the GPU hang that revealed the truth, as the CS
gleefully executed beyond the end of the golden renderstate batch, a good
indicator for a GTT TLB miss.
