"While I hoped things would calm down, the world hasn't joined with me,
but it's a few things scattered over a wide area. The i915 workarounds
regression fix is probably the largest, the rest are more usual sized.
We also get some new AMD PCI IDs.
There is also a patch in here to MAINTAINERS to added Daniel as an
official DRM toplevel co-maintainer, he's decided he wants to step up

- power management fixes
- locking warning fix
nouveau:
- framebuffer flushing fix
- memory leak fix
- tegra device init regression fix
vmwgfx:
- OOM kernel memory fix
- excess return in function fix
i915:
- the biggest fix is a regression fix where workarounds weren't
getting reapplied after a gpu hang causing further crashing, this
fixes the workaround application to make it happen again
- GPU hang fixes for Braswell and some GEN3 GPUs
- GVT fix for broadwell tiling

MAINTAINERS: Daniel for drm co-maintainer
lkml and Linus gained a CoC, and it's serious this time. Which means
my no 1 reason for declining to officially step up as drm maintainer
is gone, and I didn't find any new good excuse.
I chatted with a few people in private already, and the biggest
concern is that I mislay my community hat and start running around
with my intel hat only. Or some other convenient abuse of trust.
That's why this patch doesn't just need a lot of acks that mean "yeah
seems fine to me", but a lot of acks that mean "yeah we'll tell you
when you're over the line and usurp you from that comfy chair if you
don't get it". Which I think we've been done a fairly good job here at
dri-devel in general, but better to be clear.
Rough idea is that I'll do this for maybe 2-3 years, helping Dave
figure out a group model for drm overall. And getting the tooling and
infrastructure for that off the ground. Then step down again because
some other shiny thing that needs chasing. Of course as plans tend to
do, this one will probably pan out a bit different in reality.

drm/i915/execlists: Apply a full mb before execution for Braswell
Braswell is really picky about having our writes posted to memory before
we execute or else the GPU may see stale values. A wmb() is insufficient
as it only ensures the writes are visible to other cores, we need a full
mb() to ensure the writes are in memory and visible to the GPU.
The most frequent failure in flushing before execution is that we see

selftests/seccomp: Remove SIGSTOP si_pid check
Commit
f149b3155744 ("signal: Never allocate siginfo for SIGKILL or SIGSTOP")
means that the seccomp selftest cannot check si_pid under SIGSTOP anymore.
Since it's believed[1] there are no other userspace things depending on the
old behavior, this removes the behavioral check in the selftest, since it's
more a "extra" sanity check (which turns out, maybe, not to have been
useful to test).

dm thin: send event about thin-pool state change _after_ making it
Sending a DM event before a thin-pool state change is about to happen is
a bug. It wasn't realized until it became clear that userspace response
to the event raced with the actual state change that the event was
meant to notify about.
Fix this by first updating internal thin-pool state to reflect what the
DM event is being issued about. This fixes a long-standing racey/buggy
userspace device-mapper-test-suite 'resize_io' test that would get an

It causes new warnings [1] on shutdown when running the Google Kevin or

backlight: pwm_bl: Fix brightness levels for non-DT case.
Commit '
88ba95bedb79 ("backlight: pwm_bl: Compute brightness of LED

brightness table when there isn't the brightness-levels property in the
DT. Unfortunately the changes made broke the pwm backlight for the
non-DT boards.
Usually, the non-DT boards don't pass the brightness levels via platform
data, instead, it sets the max_brightness in their platform data and the
driver calculates the level without a table. The offending patch assumed
that when there is no brightness levels table we should create one, but this
is clearly wrong for the non-DT case.
After this patch the code handles the DT and the non-DT case taking in
consideration also if max_brightness is set or not.

The CP rings are accounted differently on the new 57500 chips. There

The output parameter max_cp should be the maximum NQs capped by

- Unless and until the core mm handles memory hotplug units smaller

Memory" ranges within a section, so additional padding injection is
added for that case.

Revert "mm, thp: consolidate THP gfp handling into alloc_hugepage_direct_gfpmask"
This reverts commit
89c83fb539f95491be80cdd5158e6f0ce329e317.
This should have been done as part of
2f0799a0ffc0 ("mm, thp: restore
node-local hugepage allocations"). The movement of the thp allocation
policy from alloc_pages_vma() to alloc_hugepage_direct_gfpmask() was
intended to only set __GFP_THISNODE for mempolicies that are not
MPOL_BIND whereas the revert could set this regardless of mempolicy.
While the check for MPOL_BIND between alloc_hugepage_direct_gfpmask()
and alloc_pages_vma() was racy, that has since been removed since the
revert. What is left is the possibility to use __GFP_THISNODE in
policy_node() when it is unexpected because the special handling for
hugepages in alloc_pages_vma() was removed as part of the consolidation.
Secondly, prior to
89c83fb539f9, alloc_pages_vma() implemented a somewhat
different policy for hugepage allocations, which were allocated through
alloc_hugepage_vma(). For hugepage allocations, if the allocating
process's node is in the set of allowed nodes, allocate with
__GFP_THISNODE for that node (for MPOL_PREFERRED, use that node with
__GFP_THISNODE instead). This was changed for shmem_alloc_hugepage() to
allow fallback to other nodes in
89c83fb539f9 as it did for new_page() in
mm/mempolicy.c which is functionally different behavior and removes the
requirement to only allocate hugepages locally.
So this commit does a full revert of
89c83fb539f9 instead of the partial

Revert "net/ibm/emac: wrong bit is used for STA control"
This reverts commit
624ca9c33c8a853a4a589836e310d776620f4ab9.
This commit is completely bogus. The STACR register has two formats, old
and new, depending on the version of the IP block used. There's a pair of
device-tree properties that can be used to specify the format used:
has-inverted-stacr-oc
has-new-stacr-staopc
What this commit did was to change the bit definition used with the old
parts to match the new parts. This of course breaks the driver on all
the old ones.
Instead, the author should have set the appropriate properties in the
device-tree for the variant used on his board.

====================
Fix slab out-of-bounds on insufficient headroom for IPv6 packets
Patch 1/2 fixes a slab out-of-bounds occurring with short SCTP packets over
IPv4 over L2TP over IPv6 on a configuration with relatively low HEADER_MAX.
Patch 2/2 makes sure we avoid writing before the allocated buffer in
neigh_hh_output() in case the headroom is enough for the unaligned hardware
header size, but not enough for the aligned one, and that we warn if we hit
this condition.

neighbour: Avoid writing before skb->head in neigh_hh_output()
While skb_push() makes the kernel panic if the skb headroom is less than
the unaligned hardware header size, it will proceed normally in case we
copy more than that because of alignment, and we'll silently corrupt
adjacent slabs.
In the case fixed by the previous patch,
"ipv6: Check available headroom in ip6_xmit() even without options", we
end up in neigh_hh_output() with 14 bytes headroom, 14 bytes hardware
header and write 16 bytes, starting 2 bytes before the allocated buffer.
Always check we're not writing before skb->head and, if the headroom is
not enough, warn and drop the packet.
v2:
- instead of panicking with BUG_ON(), WARN_ON_ONCE() and drop the packet
(Eric Dumazet)
- if we avoid the panic, though, we need to explicitly check the headroom
before the memcpy(), otherwise we'll have corrupted slabs on a running
kernel, after we warn
- use __skb_push() instead of skb_push(), as the headroom check is
already implemented here explicitly (Eric Dumazet)

ipv6: Check available headroom in ip6_xmit() even without options
Even if we send an IPv6 packet without options, MAX_HEADER might not be
enough to account for the additional headroom required by alignment of
hardware headers.
On a configuration without HYPERV_NET, WLAN, AX25, and with IPV6_TUNNEL,
sending short SCTP packets over IPv4 over L2TP over IPv6, we start with
100 bytes of allocated headroom in sctp_packet_transmit(), end up with 54
bytes after l2tp_xmit_skb(), and 14 bytes in ip6_finish_output2().
Those would be enough to append our 14 bytes header, but we're going to
align that to 16 bytes, and write 2 bytes out of the allocated slab in
neigh_hh_output().

tcp: lack of available data can also cause TSO defer
tcp_tso_should_defer() can return true in three different cases :
1) We are cwnd-limited
2) We are rwnd-limited
3) We are application limited.
Neal pointed out that my recent fix went too far, since
it assumed that if we were not in 1) case, we must be rwnd-limited
Fix this by properly populating the is_cwnd_limited and
is_rwnd_limited booleans.
After this change, we can finally move the silly check for FIN
flag only for the application-limited case.
The same move for EOR bit will be handled in net-next,

dm zoned: Fix target BIO completion handling
struct bioctx includes the ref refcount_t to track the number of I/O
fragments used to process a target BIO as well as ensure that the zone
of the BIO is kept in the active state throughout the lifetime of the
BIO. However, since decrementing of this reference count is done in the
target .end_io method, the function bio_endio() must be called multiple
times for read and write target BIOs, which causes problems with the
value of the __bi_remaining struct bio field for chained BIOs (e.g. the
clone BIO passed by dm core is large and splits into fragments by the
block layer), resulting in incorrect values and inconsistencies with the
BIO_CHAIN flag setting. This is turn triggers the BUG_ON() call:
BUG_ON(atomic_read(&bio->__bi_remaining) <= 0);
in bio_remaining_done() called from bio_endio().
Fix this ensuring that bio_endio() is called only once for any target
BIO by always using internal clone BIOs for processing any read or
write target BIO. This allows reference counting using the target BIO
context counter to trigger the target BIO completion bio_endio() call
once all data, metadata and other zone work triggered by the BIO
complete.
Overall, this simplifies the code too as the target .end_io becomes
unnecessary and differences between read and write BIO issuing and
completion processing disappear.
