Pull thermal management fix from Zhang Rui:
"A single revert from a recently introduced problem.
Specifics:
Commit 7611fb68062f ("thermal: thermal_hwmon: Convert to
hwmon_device_register_with_info()"), which was introduced in 4.10-rc5,
uses new hwmon API. But this breaks some soc thermal driver because
the new hwmon API has a strict rule for the hwmon device name. Revert
the offending commit as a quick solution for 4.10"

Quotacheck runs at mount time in situations where quota accounting must
be recalculated. In doing so, it uses bulkstat to visit every inode in
the filesystem. Historically, every inode processed during quotacheck
was released and immediately tagged for reclaim because quotacheck runs
before the superblock is marked active by the VFS. In other words,
the final iput() lead to an immediate ->destroy_inode() call, which
allowed the XFS background reclaim worker to start reclaiming inodes.
Commit 17c12bcd3 ("xfs: when replaying bmap operations, don't let
unlinked inodes get reaped") marks the XFS superblock active sooner as
part of the mount process to support caching inodes processed during log
recovery. This occurs before quotacheck and thus means all inodes
processed by quotacheck are inserted to the LRU on release. The
s_umount lock is held until the mount has completed and thus prevents
the shrinkers from operating on the sb. This means that quotacheck can
excessively populate the inode LRU and lead to OOM conditions on systems
without sufficient RAM.
Update the quotacheck bulkstat handler to set XFS_IGET_DONTCACHE on
inodes processed by quotacheck. This causes ->drop_inode() to return 1
and in turn causes iput_final() to evict the inode. This preserves the
original quotacheck behavior and prevents it from overloading the LRU
and running out of memory.

With some gcc versions, we get a warning about the eicon driver,
and that currently shows up as the only remaining warning in one
of the build bots:
In file included from ../drivers/isdn/hardware/eicon/message.c:30:0:
eicon/message.c: In function 'mixer_notify_update':
eicon/platform.h:333:18: warning: array subscript is above array bounds [-Warray-bounds]
The code is easily changed to open-code the unusual PUT_WORD() line
causing this to avoid the warning.

====================
various gtp fixes
I'm sorry for the compile error mess up in the last version.
It's no excuse for not test compiling, but the hunks got lost in
a rebase.
This is the part of the previous "simple gtp improvements" series
that Pablo indicated should go into net.
The addition of the module alias fixes genl family autoloading,
clearing the DF bit fixes a protocol violation in regard to the
specification and the netns comparison fixes a corner case of
cross netns recv.

The use of the passed through netlink src_net to check for a
cross netns operation was wrong. Using the GTP socket and the
GTP netdevice is always correct (even if the netdev has been
moved to new netns after link creation).
Remove the now obsolete net field from gtp_dev.

Unlike ipv4, this control socket is shared by all cpus so we cannot use
it as scratchpad area to annotate the mark that we pass to ip6_xmit().
Add a new parameter to ip6_xmit() to indicate the mark. The SCTP socket
family caches the flowi6 structure in the sctp_transport structure, so
we cannot use to carry the mark unless we later on reset it back, which
I discarded since it looks ugly to me.

Resuming from RPM can happen while already holding
dev->mode_config.mutex. This means we can't actually handle fbcon in
any RPM resume workers, since restoring fbcon requires grabbing
dev->mode_config.mutex again. So move the fbcon suspend/resume code into
it's own worker, and rely on that instead to avoid deadlocking.
This fixes more deadlocks for runtime suspending the GPU on the ThinkPad
W541. Reproduction recipe:
- Get a machine with both optimus and a nvidia card with connectors
attached to it
- Wait for the nvidia GPU to suspend
- Attempt to manually reprobe any of the connectors on the nvidia GPU
using sysfs
- *deadlock*

As it turns out, on cards that actually have CRTCs on them we're already
calling drm_kms_helper_poll_enable(drm_dev) from
nouveau_display_resume() before we call it in
nouveau_pmops_runtime_resume(). This leads us to accidentally trying to
enable polling twice, which results in a potential deadlock between the
RPM locks and drm_dev->mode_config.mutex if we end up trying to enable
polling the second time while output_poll_execute is running and holding
the mode_config lock. As such, make sure we only enable polling in
nouveau_pmops_runtime_resume() if we need to.
This fixes hangs observed on the ThinkPad W541

When you snapshot a subvolume containing a subvolume, you get a
placeholder directory where the subvolume would be. These directory
inodes have ->i_ops set to btrfs_dir_ro_inode_operations. Previously,
these i_ops didn't include the xattr operation callbacks. The conversion
to xattr_handlers missed this case, leading to bogus attempts to set
xattrs on these inodes. This manifested itself as failures when running
delayed inodes.
To fix this, clear IOP_XATTR in ->i_opflags on these inodes.

In a bmapx call, bmv_count is the total size of the array, including the
zeroth element that userspace uses to supply the search key. The output
array starts at offset 1 so that we can set up the user for the next
invocation. Since we now can split an extent into multiple bmap records
due to shared/unshared status, we have to be careful that we don't
overflow the output array.
In the original patch f86f403794b ("xfs: teach get_bmapx about shared
extents and the CoW fork") I used cur_ext (the output index) to check
for overflows, albeit with an off-by-one error. Since nexleft no longer
describes the number of unfilled slots in the output, we can rip all
that out and use cur_ext for the overflow check directly.
Failure to do this causes heap corruption in bmapx callers such as
xfs_io and xfs_scrub. xfs/328 can reproduce this problem.

Pull drm revert from Dave Airlie:
"Revert one patch missing some prereqs.
One of the connector fixes was missing some prereqs, we have an
alternate driver fix that should work that I'll send tomorrow.
Today is a holiday here so quickly smashing this out"
Daniel Vetter explains:
"I pushed a locking change to fix a nouveau rpm issue to -fixes that
needed the connector_list rework. And that's only in -next, but I
missed that. Dave has the revert in a pull, and he'll follow-up with
the hack nouveau patch for 4.10, and then we'll reapply the proper fix
again for -next and revert the hacks. A bit a mess, but should be
sorted soon"

This patch performs dma sync operations on nvme_command
and nvme_completion.
nvme_command is synced
(a) on receiving of the recv queue completion for cpu access.
(b) before posting recv wqe back to rdma adapter for device access.
nvme_completion is synced
(a) on receiving of the recv queue completion of associated
nvme_command for cpu access.
(b) before posting send wqe to rdma adapter for device access.

just make sure we only call delete_ctrl once.

If we try to allocate memory pages to back an xfs_buf that we're trying
to read, it's possible that we'll be so short on memory that the page
allocation fails. For a blocking read we'll just wait, but for
readahead we simply dump all the pages we've collected so far.
Unfortunately, after dumping the pages we neglect to clear the
_XBF_PAGES state, which means that the subsequent call to xfs_buf_free
thinks that b_pages still points to pages we own. It then double-frees
the b_pages pages.
This results in screaming about negative page refcounts from the memory
manager, which xfs oughtn't be triggering. To reproduce this case,
mount a filesystem where the size of the inodes far outweighs the
availalble memory (a ~500M inode filesystem on a VM with 300MB memory
did the trick here) and run bulkstat in parallel with other memory
eating processes to put a huge load on the system. The "check summary"
phase of xfs_scrub also works for this purpose.

In the small buffer case during driver unload we currently use
put_page instead of dev_kfree_skb. Resolve this by adding a check
for virtnet mode when checking XDP queue type. Also name the
function so that the code reads correctly to match the additional
check.

r8152: fix scheduling napi
v3:
simply the argument for patch #3. Replace &tp->napi with napi.
v2:
Add smp_mb__after_atomic() for patch #1.
v1:
Scheduling the napi during the following periods would let it be ignored.
And the events wouldn't be handled until next napi_schedule() is called.
1. after napi_disable and before napi_enable().
2. after all actions of napi function is completed and before calling
napi_complete().
If no next napi_schedule() is called, tx or rx would stop working.
In order to avoid these situations, the followings solutions are applied.
1. prevent start_xmit() from calling napi_schedule() during runtime suspend
or after napi_disable().
2. re-schedule the napi for tx if it is necessary.
3. check if any rx is finished or not after napi_enable().

Schedule the napi after napi_enable() for rx, if it is necessary.
If the rx is completed when napi is disabled, the sheduling of napi
would be lost. Then, no one handles the rx packet until next napi
is scheduled.

Adjust the setting of the flag of SELECTIVE_SUSPEND to prevent start_xmit()
from calling napi_schedule() directly during runtime suspend.
After calling napi_disable() or clearing the flag of WORK_ENABLE,
scheduling the napi is useless.
