And also put the overview section into the KMS Properties part of the
docs, instead of randomly-placed within the helpers - this is part of
the uabi.
With this patch I think drm_crtc.[hc] is cleaned up and entirely
documented.

And shuffle the kernel-doc structure a bit since drm_crtc.[hc] now
only contains CRTC-related functions and structures.
v2:
- rebase onto drm-misc
- don't forget to move drm_mode_config_cleanup.
- move 2 internal decls under the right heading (Chris)

This reverts commit a68362fe3e84fcbedd49939aa200519aa5410135.
Adding new mode flags willy nilly breaks existing userspace. We need to
coordinate this better, potentially with a new client cap that only
exposes the aspect ratio flags when userspace is prepared for them
(similar to what we do with stereo 3D modes).

By popular DRM demand, introduce mutex_trylock_recursive() to fix up the
two GEM users.
Without this it is very easy for these drivers to get stuck in
low-memory situations and trigger OOM. Work is in progress to remove the
need for this in at least i915.

I want to move dumb buffer documentation into the right vfuncs, and
for that I first need to be able to pull that into kerneldoc without
having to clean up all of drmP.h. Also, header-splitting is nice.
While at it shuffle all the function declarations for drm_drv.c into
the right spots, and drop the kerneldoc for drm_minor_acquire/release
since it's only used internally.
v2: Keep all existing copyright notices (Chris).

iommu_group_get_for_dev() expects that the IOMMU driver's device_group
callback return a group with a reference held for the given device.
Whilst allocating a new group is fine, and pci_device_group() correctly
handles reusing an existing group, there is no general means for IOMMU
drivers doing their own group lookup to take additional references on an
existing group pointer without having to also store device pointers or
resort to elaborate trickery.
Add an IOMMU-driver-specific function to fill the hole.

Now since fetch_task_cputime() has no other users than task_cputime(),
its code could be used directly in task_cputime().
Moreover since only 2 task_cputime() calls of 17 use a NULL argument,
we can add dummy variables to those calls and remove NULL checks from
task_cputimes().
Also remove NULL checks from task_cputimes_scaled().

Only s390 and powerpc have hardware facilities allowing to measure
cputimes scaled by frequency. On all other architectures
utimescaled/stimescaled are equal to utime/stime (however they are
accounted separately).
Remove {u,s}timescaled accounting on all architectures except
powerpc and s390, where those values are explicitly accounted
in the proper places.

kbuild spotted this error, with drm/msm patches that add a new
modeset-lock in the driver and driver built as a module:
ERROR: "crtc_ww_class" [drivers/gpu/drm/msm/msm.ko] undefined!
Really the only reason for crtc_ww_class not being internal to
drm_modeset_lock.c is that drm_modeset_lock_init() was static-inline
(for no particularly good reason).
Fix that, and move crtc_ww_class into drm_modeset_lock.c.

This is fixed by using the kref_get_unless_zero() as a full memory
barrier to validate the fence is still the current exclusive fence before
returning it back to the caller. (Note the fix only requires using
dma_fence_get_rcu() and correct handling, but we may as well use the
helper rather than inline equivalent code.)
Note: Issue can only be hit with the i915 driver.

This patch is a cleanup of EMU1010 dock probing code in emu10k1 driver
to use work instead of kthread in a loop. The work is lighter and
easier to control than kthread, in general.
Instead of a loop with the explicit sleep, we do simply
delayed-schedule the work. At suspend/resume callbacks, the work is
canceled and restarted, respectively.

we no longer need to support modifying the resource table while the

This saves us from the table_ptr dance, but more importantly allow the

Pull networking fixes from David Miller:
1) Fix off by one wrt. indexing when dumping /proc/net/route entries,
from Alexander Duyck.
2) Fix lockdep splats in iwlwifi, from Johannes Berg.
3) Cure panic when inserting certain netfilter rules when NFT_SET_HASH
is disabled, from Liping Zhang.

5) Disable UFO when path will apply IPSEC tranformations, from Jakub
Sitnicki.
6) Don't bogusly double cwnd in dctcp module, from Florian Westphal.
7) skb_checksum_help() should never actually use the value "0" for the
resulting checksum, that has a special meaning, use CSUM_MANGLED_0
instead. From Eric Dumazet.
8) Per-tx/rx queue statistic strings are wrong in qed driver, fix from
Yuval MIntz.
9) Fix SCTP reference counting of associations and transports in
sctp_diag. From Xin Long.
10) When we hit ip6tunnel_xmit() we could have come from an ipv4 path in
a previous layer or similar, so explicitly clear the ipv6 control
block in the skb. From Eli Cooper.
11) Fix bogus sleeping inside of inet_wait_for_connect(), from WANG
Cong.
12) Correct deivce ID of T6 adapter in cxgb4 driver, from Hariprasad
Shenai.
13) Fix potential access past the end of the skb page frag array in
tcp_sendmsg(). From Eric Dumazet.

from David Ahern.
15) Don't return an error in tcp_sendmsg() if we wronte any bytes
successfully, from Eric Dumazet.
16) Extraneous unlocks in netlink_diag_dump(), we removed the locking
but forgot to purge these unlock calls. From Eric Dumazet.

the attrbuf, from WANG Cong.
18) cgroupstats netlink policy table is mis-sized, from WANG Cong.
19) Several XDP bug fixes in mlx5, from Saeed Mahameed.
20) Fix several device refcount leaks in network drivers, from Johan
Hovold.
21) icmp6_send() should use skb dst device not skb->dev to determine L3
routing domain. From David Ahern.
22) ip_vs_genl_family sets maxattr incorrectly, from WANG Cong.
23) We leak new macvlan port in some cases of maclan_common_netlink()
errors. Fix from Gao Feng.
24) Similar to the icmp6_send() fix, icmp_route_lookup() should
determine L3 routing domain using skb_dst(skb)->dev not skb->dev.
Also from David Ahern.
25) Several fixes for route offloading and FIB notification handling in
mlxsw driver, from Jiri Pirko.
26) Properly cap __skb_flow_dissect()'s return value, from Eric Dumazet.
27) Fix long standing regression in ipv4 redirect handling, wrt.
validating the new neighbour's reachability. From Stephen Suryaputra
Lin.
28) If sk_filter() trims the packet excessively, handle it reasonably in
tcp input instead of exploding. From Eric Dumazet.
29) Fix handling of napi hash state when copying channels in sfc driver,
from Bert Kenward.

Although rcutorture will occasionally do a 50-millisecond grace-period
delay, these delays are quite rare. And rightly so, because otherwise
the read rate would be quite low. Thie means that it can be important
to identify whether or not a given run contained a long-delay read.
This commit therefore inserts a trace_rcu_torture_read() event to flag
runs containing long delays.

Similar to commit 14135f30e33c ("inet: fix sleeping inside inet_wait_for_connect()"),
sk_wait_event() needs to fix too, because release_sock() is blocking,
it changes the process state back to running after sleep, which breaks
the previous prepare_to_wait().
Switch to the new wait API.

With the new dma_{map,unmap}_resource() functions added to the DMA API
for the benefit of cases like slave DMA, add suitable implementations to
the arsenal of our generic layer. Since cache maintenance should not be
a concern, these can both be standalone callback implementations without
the need for arch code wrappers.

Pablo Neira Ayuso says:
====================
Netfilter updates for net-next
The following patchset contains a second batch of Netfilter updates for
your net-next tree. This includes a rework of the core hook
infrastructure that improves Netfilter performance by ~15% according to
synthetic benchmarks. Then, a large batch with ipset updates, including
a new hash:ipmac set type, via Jozsef Kadlecsik. This also includes a
couple of assorted updates.
Regarding the core hook infrastructure rework to improve performance,
using this simple drop-all packets ruleset from ingress:
nft add table netdev x
nft add chain netdev x y { type filter hook ingress device eth0 priority 0\; }
nft add rule netdev x y drop
And generating traffic through Jesper Brouer's
samples/pktgen/pktgen_bench_xmit_mode_netif_receive.sh script using -i
option. perf report shows nf_tables calls in its top 10:
17.30% kpktgend_0 [nf_tables] [k] nft_do_chain
15.75% kpktgend_0 [kernel.vmlinux] [k] __netif_receive_skb_core
10.39% kpktgend_0 [nf_tables_netdev] [k] nft_do_chain_netdev
I'm measuring here an improvement of ~15% in performance with this
patchset, so we got +2.5Mpps more. I have used my old laptop Intel(R)
Core(TM) i5-3320M CPU @ 2.60GHz 4-cores.
This rework contains more specifically, in strict order, these patches:
1) Remove compile-time debugging from core.
2) Remove obsolete comments that predate the rcu era. These days it is
well known that a Netfilter hook always runs under rcu_read_lock().
3) Remove threshold handling, this is only used by br_netfilter too.
We already have specific code to handle this from br_netfilter,
so remove this code from the core path.
4) Deprecate NF_STOP, as this is only used by br_netfilter.
5) Place nf_state_hook pointer into xt_action_param structure, so
this structure fits into one single cacheline according to pahole.
This also implicit affects nftables since it also relies on the
xt_action_param structure.
6) Move state->hook_entries into nf_queue entry. The hook_entries
pointer is only required by nf_queue(), so we can store this in the
queue entry instead.
7) use switch() statement to handle verdict cases.
8) Remove hook_entries field from nf_hook_state structure, this is only
required by nf_queue, so store it in nf_queue_entry structure.
9) Merge nf_iterate() into nf_hook_slow() that results in a much more
simple and readable function.
10) Handle NF_REPEAT away from the core, so far the only client is
nf_conntrack_in() and we can restart the packet processing using a
simple goto to jump back there when the TCP requires it.
This update required a second pass to fix fallout, fix from
Arnd Bergmann.
11) Set random seed from nft_hash when no seed is specified from
userspace.
12) Simplify nf_tables expression registration, in a much smarter way
to save lots of boiler plate code, by Liping Zhang.
13) Simplify layer 4 protocol conntrack tracker registration, from
Davide Caratti.
14) Missing CONFIG_NF_SOCKET_IPV4 dependency for udp4_lib_lookup, due
to recent generalization of the socket infrastructure, from Arnd
Bergmann.
15) Then, the ipset batch from Jozsef, he describes it as it follows:
* Cleanup: Remove extra whitespaces in ip_set.h
* Cleanup: Mark some of the helpers arguments as const in ip_set.h
* Cleanup: Group counter helper functions together in ip_set.h
* struct ip_set_skbinfo is introduced instead of open coded fields
in skbinfo get/init helper funcions.
* Use kmalloc() in comment extension helper instead of kzalloc()
because it is unnecessary to zero out the area just before
explicit initialization.
* Cleanup: Split extensions into separate files.
* Cleanup: Separate memsize calculation code into dedicated function.
* Cleanup: group ip_set_put_extensions() and ip_set_get_extensions()
together.
* Add element count to hash headers by Eric B Munson.
* Add element count to all set types header for uniform output
across all set types.
* Count non-static extension memory into memsize calculation for
userspace.
* Cleanup: Remove redundant mtype_expire() arguments, because
they can be get from other parameters.
* Cleanup: Simplify mtype_expire() for hash types by removing
one level of intendation.
* Make NLEN compile time constant for hash types.
* Make sure element data size is a multiple of u32 for the hash set
types.
* Optimize hash creation routine, exit as early as possible.
* Make struct htype per ipset family so nets array becomes fixed size
and thus simplifies the struct htype allocation.
* Collapse same condition body into a single one.
* Fix reported memory size for hash:* types, base hash bucket structure
was not taken into account.
* hash:ipmac type support added to ipset by Tomasz Chilinski.
* Use setup_timer() and mod_timer() instead of init_timer()
by Muhammad Falak R Wani, individually for the set type families.
16) Remove useless connlabel field in struct netns_ct, patch from
Florian Westphal.
17) xt_find_table_lock() doesn't return ERR_PTR() anymore, so simplify
{ip,ip6,arp}tables code that uses this.
