Currently, the last object in the execlist is the always the batch.
However, when building the batch buffer we often know the batch object
first and if we can use the first slot in the execlist we can emit
relocation instructions relative to it immediately and avoid a separate
pass to adjust the relocations to point to the last execlist slot.

Enables access to OA unit metrics for BDW, CHV, SKL and BXT which all
share (more-or-less) the same OA unit design.
Of particular note in comparison to Haswell: some OA unit HW config
state has become per-context state and as a consequence it is somewhat
more complicated to manage synchronous state changes from the cpu while
there's no guarantee of what context (if any) is currently actively
running on the gpu.
The periodic sampling frequency which can be particularly useful for
system-wide analysis (as opposed to command stream synchronised
MI_REPORT_PERF_COUNT commands) is perhaps the most surprising state to
have become per-context save and restored (while the OABUFFER
destination is still a shared, system-wide resource).
This support for gen8+ takes care to consider a number of timing
challenges involved in synchronously updating per-context state
primarily by programming all config state from the cpu and updating all
current and saved contexts synchronously while the OA unit is still
disabled.
The driver intentionally avoids depending on command streamer
programming to update OA state considering the lack of synchronization
between the automatic loading of OACTXCONTROL state (that includes the
periodic sampling state and enable state) on context restore and the
parsing of any general purpose BB the driver can control. I.e. this
implementation is careful to avoid the possibility of a context restore
temporarily enabling any out-of-date periodic sampling state. In
addition to the risk of transiently-out-of-date state being loaded
automatically; there are also internal HW latencies involved in the
loading of MUX configurations which would be difficult to account for
from the command streamer (and we only want to enable the unit when once
the MUX configuration is complete).
Since the Gen8+ OA unit design no longer supports clock gating the unit
off for a single given context (which effectively stopped any progress
of counters while any other context was running) and instead supports
tagging OA reports with a context ID for filtering on the CPU, it means
we can no longer hide the system-wide progress of counters from a
non-privileged application only interested in metrics for its own
context. Although we could theoretically try and subtract the progress
of other contexts before forwarding reports via read() we aren't in a
position to filter reports captured via MI_REPORT_PERF_COUNT commands.
As a result, for Gen8+, we always require the
dev.i915.perf_stream_paranoid to be unset for any access to OA metrics
if not root.
v5: Drain submitted requests when enabling metric set to ensure no
lite-restore erases the context image we just updated (Lionel)
v6: In addition to drain, switch to kernel context & update all
context in place (Chris)
v7: Add missing mutex_unlock() if switching to kernel context fails
(Matthew)
v8: Simplify OA period/flex-eu-counters programming by using the
batchbuffer instead of modifying ctx-image (Lionel)
v9: Back to updating the context image (due to erroneous testing,
batchbuffer programming the OA unit doesn't actually work)
(Lionel)
Pin context before updating context image (Chris)
Drop MMIO programming now that we switch to a kernel context with
right values in initial context image (Chris)
v10: Just pin_map the contexts we want to modify or let the
configuration happen on first use (Chris)
v11: Update kernel context OA config through the batchbuffer rather
than on the fly ctx-image update (Lionel)
v12: Rework OA context registers update again by swithing away from
user contexts and reconfiguring the kernel context through the
batchbuffer and updating all the other contexts' context image.
Also take care to lock slice/subslice configuration when OA is
on. (Lionel)

Andrey Konovalov reported crashes in ipv4_mtu()
I could reproduce the issue with KASAN kernels, between
10.246.7.151 and 10.246.7.152 :
1) 20 concurrent netperf -t TCP_RR -H 10.246.7.152 -l 1000 &
2) At the same time run following loop :
while :
do
ip ro add 10.246.7.152 dev eth0 src 10.246.7.151 mtu 1500
ip ro del 10.246.7.152 dev eth0 src 10.246.7.151 mtu 1500
done
Cong Wang attempted to add back rt->fi in commit
82486aa6f1b9 ("ipv4: restore rt->fi for reference counting")
but this proved to add some issues that were complex to solve.
Instead, I suggested to add a refcount to the metrics themselves,
being a standalone object (in particular, no reference to other objects)
I tried to make this patch as small as possible to ease its backport,
instead of being super clean. Note that we believe that only ipv4 dst
need to take care of the metric refcount. But if this is wrong,
this patch adds the basic infrastructure to extend this to other
families.
Many thanks to Julian Anastasov for reviewing this patch, and Cong Wang
for his efforts on this problem.

It appears that TCP checksum offloading has been broken for
Q-in-Q vlans. The behavior was execerbated by the
series
commit afb0bc972b52 ("Merge branch 'stacked_vlan_tso'")
that that enabled accleleration features on stacked vlans.
However, event without that series, it is possible to trigger
this issue. It just requires a lot more specialized configuration.
The root cause is the interaction between how
netdev_intersect_features() works, the features actually set on
the vlan devices and HW having the ability to run checksum with
longer headers.
The issue starts when netdev_interesect_features() replaces
NETIF_F_HW_CSUM with a combination of NETIF_F_IP_CSUM | NETIF_F_IPV6_CSUM,
if the HW advertises IP|IPV6 specific checksums. This happens
for tagged and multi-tagged packets. However, HW that enables
IP|IPV6 checksum offloading doesn't gurantee that packets with
arbitrarily long headers can be checksummed.
This patch disables IP|IPV6 checksums on the packet for multi-tagged
packets.

Constructing the name takes the majority of the time for allocating a
sync_file to wrap a fence, and the name is very rarely used (only via
the sync_file status user interface). To reduce the impact on the common
path (that of creating sync_file to pass around), defer the construction
of the name until it is first used.
v2: Update kerneldoc (kbuild test robot)
v3: sync_debug.c was peeking at the name
v4: Comment upon the potential race between two users of
sync_file_get_name() and claim that such a race is below the level of
notice. However, to prevent any future nuisance, use a global spinlock
to serialize the assignment of the name.
v5: Completely avoid the read/write race by only storing the name passed
in from the user inside sync_file->user_name and passing in a buffer to
dynamically construct the name otherwise.

The bug resulted in setting skb->l4_hash, even-though the

Brought up by both Laurent and Andrzej when reviewing the new
->mode_valid hooks. Since mode_fixup is just a simpler version of the
much more generic atomic_check we can't really unify it with
mode_valid. Most drivers should probably switch their current
mode_fixup code to either the new mode_valid or the atomic_check
hooks, but e.g. that doesn't exist yet for bridges, and for CRTCs the
situation is a bit more complicated. Hence there's no clear
equivalence between mode_fixup and mode_valid, even if it looks like
that at first glance.

This adds a new callback to crtc, encoder and bridge helper functions
called mode_valid(). This callback shall be implemented if the
corresponding component has some sort of restriction in the modes
that can be displayed. A NULL callback implicates that the component
can display all the modes.
We also change the documentation so that the new and old callbacks
are correctly documented.
Only the callbacks were implemented to simplify review process,
following patches will make use of them.
Changes in v2 from Daniel:
- Update the warning about how modes aren't filtered in atomic_check -
the heleprs help out a lot more now.
- Consistenly roll out that warning, crtc/encoder's atomic_check
missed it.
- Sprinkle more links all over the place, so it's easier to see where
this stuff is used and how the differen hooks are related.
- Note that ->mode_valid is optional everywhere.
- Explain why the connector's mode_valid is special and does _not_ get
called in atomic_check.
v3: Document what can and cannot be checked in mode_valid a bit better
(Andrjez). Answer: Only allowed to look at the mode, nothing else.

Currently when firmware command gets stuck or it takes long time to
complete, the driver command will get timeout and the command slot is
freed and can be used for new commands, and if the firmware receive new
command on the old busy slot its behavior is unexpected and this could
be harmful.
To fix this when the driver command gets timeout we return failure,
but we don't free the command slot and we wait for the firmware to
explicitly respond to that command.
Once all the entries are busy we will stop processing new firmware
commands.

When I introduced ptracer_cred I failed to consider the weirdness of
fork where the task_struct copies the old value by default. This
winds up leaving ptracer_cred set even when a process forks and
the child process does not wind up being ptraced.
Because ptracer_cred is not set on non-ptraced processes whose
parents were ptraced this has broken the ability of the enlightenment
window manager to start setuid children.
Fix this by properly initializing ptracer_cred in ptrace_init_task
This must be done with a little bit of care to preserve the current value
of ptracer_cred when ptrace carries through fork. Re-reading the
ptracer_cred from the ptracing process at this point is inconsistent
with how PT_PTRACE_CAP has been maintained all of these years.

Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ defines to the UAPI
as a convenience.
Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up
through the atomic API, but realizing that userspace is likely to take
shortcuts and assume that the enum values are what is sent over the
wire.
As a result these defines are provided purely as a convenience to
userspace applications.

- Switched away from past tense in comments
- Add define name change to previously mis-spelled DRM_REFLECT_X comment
- Improved the comment for the DRM_MODE_REFLECT_<axis> comment

- Changed define prefix from DRM_MODE_PROP_ to DRM_MODE_
- Fix compilation errors
- Changed comment formatting
- Deduplicated comment lines
- Clarified DRM_MODE_PROP_REFLECT_ comment
Changes since v1:

====================
Netfilter/IPVS fixes for net
The following patchset contains Netfilter/IPVS fixes for your net tree,
they are:
1) When using IPVS in direct-routing mode, normal traffic from the LVS
host to a back-end server is sometimes incorrectly NATed on the way
back into the LVS host. Patch to fix this from Julian Anastasov.
2) Calm down clang compilation warning in ctnetlink due to type
mismatch, from Matthias Kaehlcke.
3) Do not re-setup NAT for conntracks that are already confirmed, this
is fixing a problem that was introduced in the previous nf-next batch.
Patch from Liping Zhang.
4) Do not allow conntrack helper removal from userspace cthelper
infrastructure if already in used. This comes with an initial patch
to introduce nf_conntrack_helper_put() that is required by this fix.
From Liping Zhang.
5) Zero the pad when copying data to userspace, otherwise iptables fails
to remove rules. This is a follow up on the patchset that sorts out
the internal match/target structure pointer leak to userspace. Patch
from the same author, Willem de Bruijn. This also comes with a build
failure when CONFIG_COMPAT is not on, coming in the last patch of
this series.
6) SYNPROXY crashes with conntrack entries that are created via
ctnetlink, more specifically via conntrackd state sync. Patch from
Eric Leblond.
7) RCU safe iteration on set element dumping in nf_tables, from
Liping Zhang.
8) Missing sanitization of immediate date for the bitwise and cmp
expressions in nf_tables.
9) Refcounting logic for chain and objects from set elements does not
integrate into the nf_tables 2-phase commit protocol.
10) Missing sanitization of target verdict in ebtables arpreply target,
from Gao Feng.

Pull ARM SoC fixes from Olof Johansson:
"We had a small batch of fixes before -rc1, but here is a larger one.
It contains a backmerge of 4.12-rc1 since some of the downstream
branches we merge had that as base; at the same time we already had
merged contents before -rc1 and rebase wasn't the right solution.
A mix of random smaller fixes and a few things worth pointing out:
- We've started telling people to avoid cross-tree shared branches if
all they're doing is picking up one or two DT-used constants from a
shared include file, and instead to use the numeric values on first
submission. Follow-up moving over to symbolic names are sent in
right after -rc1, i.e. here. It's only a few minor patches of this
type.
- Linus Walleij and others are resurrecting the 'Gemini' platform,
and wanted a cut-down platform-specific defconfig for it. So I
picked that up for them.
- Rob Herring ran 'savedefconfig' on arm64, it's a bit churny but it
helps people to prepare patches since it's a pain when defconfig
and current savedefconfig contents differs too much.
- Devicetree additions for some pinctrl drivers for Armada that were
merged this window. I'd have preferred to see those earlier but
it's not a huge deail.
The biggest change worth pointing out though since it's touching other
parts of the tree: We added prefixes to be used when cross-including
DT contents between arm64 and arm, allowing someone to #include
<arm/foo.dtsi> from arm64, and likewise. As part of that, we needed
arm/foo.dtsi to work on arm as well. The way I suggested this to Heiko
resulted in a recursive symlink.
Instead, I've now moved it out of arch/*/boot/dts/include, into a
shared location under scripts/dtc. While I was at it, I consolidated
so all architectures now behave the same way in this manner.
Rob Herring (DT maintainer) has acked it. I cc:d most other arch
maintainers but nobody seems to care much; it doesn't really affect
them since functionality is unchanged for them by default"
