Use the passed in plane_state instead of plane->state in
vlv_update_plane(). Currently the two are one and the same, but if we
start queuing up multiple plane updates they might not be.
Looks like this was rebase fail on my part.

On LLC, or even snooped, machines rendering via the GPU ends up in the CPU
cache. This cacheline dirt also needs to be flushed to main memory when
moving to an incoherent domain, such as the display's scanout engine.
Mostly, this happens because either the object is marked as dirty from
its first use or is avoided by setting the object into the display
domain from the start.
v2: Treat WT as not requiring a clflush prior to use on the display
engine as well.

* 'topic-arcpgu-fixes' of https://github.com/foss-for-synopsys-dwc-arc-processors/linux:
drm/arcpgu: Accommodate adv7511 switch to DRM bridge
|
|
ARC PGU driver starts crashing on initialization after
'commit e12c2f645557 ("drm/i2c: adv7511: Convert to drm_bridge")'
This happenes because in "arcpgu_drm_hdmi_init" function we get pointer
of "drm_i2c_encoder_driver" structure, which doesn't exist after
adv7511 hdmi encoder interface changed from slave encoder to drm bridge.
So, when we call "encoder_init" function from this structure driver
crashes.

It is because linux use an internal structure node_masks[] to
keep the best memory latency node only. However, LDOM mdesc can
contain single latency-group with multiple memory latency nodes.
If the address doesn't match the best latency node within
node_masks[], it should check for an alternative via mdesc.
The warning message should only be printed if the address
doesn't match any node_masks[] nor within mdesc. To minimize
the impact of searching mdesc every time, the last matched
mask and index is stored in a variable.

Consider two devices, A and B, where B is a child of A, and B utilizes
asynchronous suspend (it does not matter whether A is sync or async). If
B fails to suspend_noirq() or suspend_late(), or is interrupted by a
wakeup (pm_wakeup_pending()), then it aborts and sets the async_error
variable. However, device A does not (immediately) check the async_error
variable; it may continue to run its own suspend_noirq()/suspend_late()
callback. This is bad.
We can resolve this problem by doing our error and wakeup checking
(particularly, for the async_error flag) after waiting for children to
suspend, instead of before. This also helps align the logic for the noirq and
late suspend cases with the logic in __device_suspend().
It's easy to observe this erroneous behavior by, for example, forcing a
device to sleep a bit in its suspend_noirq() (to ensure the parent is
waiting for the child to complete), then return an error, and watch the
parent suspend_noirq() still get called. (Or similarly, fake a wakeup
event at the right (or is it wrong?) time.)

i_size check is a leftover from the horrors that used to play with
the page cache in that function. With the switch to ->read_iter(),
it's neither needed nor correct - for gfs2 it ends up being buggy,
since i_size is not guaranteed to be correct until later (inside
->read_iter()).

passed to filesystem's read_iter callback. But ceph_sync_read()
can't serve ITER_PIPE iov_iter correctly (ITER_PIPE iov_iter

Fixing ceph_sync_read() requires a big patch. So use default

Since now, the table with same id in multiple netnamespaces were squashed
to a single virtual router. That is not only incorrect, it also causes
error messages when trying to use RALUE register to do double remove
of FIB entries, like this one:
mlxsw_spectrum 0000:03:00.0: EMAD reg access failed (tid=facb831c00007b20,reg_id=8013(ralue),type=write,status=7(bad parameter))
Since we don't allow ports to change namespaces (NETIF_F_NETNS_LOCAL),
and the infrastructure is not yet prepared to handle netnamespaces, just
ignore FIB notification events for non-init namespaces. That is clear to
do since we don't need to offload them.

__neigh_create function works in a different way than assumed.
It passes "n" as a parameter to ndo_neigh_construct. But this "n" might
be destroyed right away before __neigh_create() returns in case there is
already another neighbour struct in the hashtable with the same dev and
primary key. That is not expected by mlxsw_sp_router_neigh_construct()
and the stored "n" points to freed memory, eventually leading to crash.
Fix this by doing tight 1:1 coupling between neighbour struct and
internal driver neigh_entry. That allows to narrow down the key in
internal driver hashtable to do lookups by "n" only.

When a LOCALINV WR is flushed, the frmr is marked STALE, then
frwr_op_unmap_sync DMA-unmaps the frmr's SGL. These STALE frmrs
are then recovered when frwr_op_map hunts for an INVALID frmr to
use.
All other cases that need frmr recovery leave that SGL DMA-mapped.
The FRMR recovery path unconditionally DMA-unmaps the frmr's SGL.
To avoid DMA unmapping the SGL twice for flushed LOCAL_INV WRs,
alter the recovery logic (rather than the hot frwr_op_unmap_sync
path) to distinguish among these cases. This solution also takes
care of the case where multiple LOCAL_INV WRs are issued for the
same rpcrdma_req, some complete successfully, but some are flushed.

====================
Netfilter fixes for net
The following patchset contains a larger than usual batch of Netfilter
fixes for your net tree. This series contains a mixture of old bugs and
recently introduced bugs, they are:
1) Fix a crash when using nft_dynset with nft_set_rbtree, which doesn't
support the set element updates from the packet path. From Liping
Zhang.
2) Fix leak when nft_expr_clone() fails, from Liping Zhang.
3) Fix a race when inserting new elements to the set hash from the
packet path, also from Liping.
4) Handle segmented TCP SIP packets properly, basically avoid that the
INVITE in the allow header create bogus expectations by performing
stricter SIP message parsing, from Ulrich Weber.
5) nft_parse_u32_check() should return signed integer for errors, from
John Linville.
6) Fix wrong allocation instead of connlabels, allocate 16 instead of
32 bytes, from Florian Westphal.
7) Fix compilation breakage when building the ip_vs_sync code with
CONFIG_OPTIMIZE_INLINING on x86, from Arnd Bergmann.
8) Destroy the new set if the transaction object cannot be allocated,
also from Liping Zhang.
9) Use device to route duplicated packets via nft_dup only when set by
the user, otherwise packets may not follow the right route, again
from Liping.
10) Fix wrong maximum genetlink attribute definition in IPVS, from
WANG Cong.
11) Ignore untracked conntrack objects from xt_connmark, from Florian
Westphal.
12) Allow to use conntrack helpers that are registered NFPROTO_UNSPEC
via CT target, otherwise we cannot use the h.245 helper, from
Florian.
13) Revisit garbage collection heuristic in the new workqueue-based
timer approach for conntrack to evict objects earlier, again from
Florian.
14) Fix crash in nf_tables when inserting an element into a verdict map,
from Liping Zhang.

To avoid having dangling function pointers left behind, reset calcit in
rtnl_unregister(), too.
This is no issue so far, as only the rtnl core registers a netlink
handler with a calcit hook which won't be unregistered, but may become
one if new code makes use of the calcit hook.

Don't pass a size larger than iov_len to kernel_sendmsg().
Otherwise it will cause a NULL pointer deref when kernel_sendmsg()
returns with rv < size.
DRBD as external module has been around in the kernel 2.4 days already.
We used to be compatible to 2.4 and very early 2.6 kernels,
we used to use
rv = sock_sendmsg(sock, &msg, iov.iov_len);
then later changed to
rv = kernel_sendmsg(sock, &msg, &iov, 1, size);
when we should have used
rv = kernel_sendmsg(sock, &msg, &iov, 1, iov.iov_len);
tcp_sendmsg() used to totally ignore the size parameter.
57be5bd ip: convert tcp_sendmsg() to iov_iter primitives
changes that, and exposes our long standing error.
Even with this error exposed, to trigger the bug, we would need to have
an environment (config or otherwise) causing us to not use sendpage()
for larger transfers, a failing connection, and have it fail "just at the
right time". Apparently that was unlikely enough for most, so this went
unnoticed for years.
Still, it is known to trigger at least some of these,
and suspected for the others:

This should go into 4.9,
and into all stable branches since and including v4.0,
which is the first to contain the exposing change.
It is correct for all stable branches older than that as well
(which contain the DRBD driver; which is 2.6.33 and up).
It requires a small "conflict" resolution for v4.4 and earlier, with v4.5
we dropped the comment block immediately preceding the kernel_sendmsg().

A bugfix introduced a harmless warning in v4.9-rc4:
drivers/net/vxlan.c: In function 'vxlan_group_used':
drivers/net/vxlan.c:947:21: error: unused variable 'sock6' [-Werror=unused-variable]
This hides the variable inside of the same #ifdef that is
around its user. The extraneous initialization is removed
at the same time, it was accidentally introduced in the
same commit.

Use the opt_* fields to determine the starting point for negotiating the
number of tx/rx completion queues with the vnic server. These contain the
number of queues that the vnic server estimates that it will be able to
allocate. While renegotiation may still occur, using the opt_* fields will
reduce the number of times this needs to happen and will prevent driver
probe timeout on systems using large numbers of ibmvnic client devices per
vnic port.

icmp_send is called in response to some event. The skb may not have
the device set (skb->dev is NULL), but it is expected to have an rt.
Update icmp_route_lookup to use the rt on the skb to determine L3
domain.

net: qcom/emac: ensure that pause frames are enabled
The qcom emac driver experiences significant packet loss (through frame
check sequence errors) if flow control is not enabled and the phy is
not configured to allow pause frames to pass through it. Therefore, we
need to enable flow control and force the phy to pass pause frames.

If the PHY has been configured to allow pause frames, then the MAC
should be configured to generate and/or accept those frames.

Pause frames are used to enable flow control. A MAC can send and
receive pause frames in order to throttle traffic. However, the PHY
must be configured to allow those frames to pass through.

We have a couple of drivers, acpi_apd.c and acpi_lpss.c,
that need to pass extra build-in properties to the devices
they create. Previously the drivers added those properties
to the struct device which is member of the struct
acpi_device, but that does not work. Those properties need
to be assigned to the struct device of the platform device
instead in order for them to become available to the
drivers.
To fix this, this patch changes acpi_create_platform_device
function to take struct property_entry pointer as parameter.

The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").
commit ("766a1fe78fc3 ARM: omap3: Add missing memory node") had
fixes for Torpedo and Overo boards, but this SOM-LV was missed.
This should help prevent the DTC warning:
"Node /memory has a reg or ranges property, but no unit name"
