0d5615d347 media: v4l2-ioctl: delete unused v4l2_disable_ioctl_locking
The last user of this 'feature' was the gspca driver. Now that
that driver has been converted to vb2 we can delete this code.

e0d51e6cef media: rc: default to idle on at startup or after reset
Any spaces events received after a reset or startup should be discarded,
so ensure the rc device is in idle mode.

This also makes it much easier to detect incorrect raw events, as we will
do in a following commit.

f17c403af9 media: dvbdev: add a mutex protecting the "mdev" pointer
During destruction, a race condition in
dvb_media_controller_disable_source() can cause a kernel crash,
because the "mdev" pointer has been read successfully while another
task executes dvb_usb_media_device_unregister(), which destroys the
object.  Example for such a crash:

acd14c181f media: v4l2-device.h: always expose mdev
The mdev field is only present if CONFIG_MEDIA_CONTROLLER is set.
But since we will need to pass the media_device to vb2 and the
control framework it is very convenient to just make this field
available all the time. If CONFIG_MEDIA_CONTROLLER is not set,
then it will just be NULL.

378e3f81cb media: omap3isp: support 64-bit version of omap3isp_stat_data
C libraries with 64-bit time_t use an incompatible format for
struct omap3isp_stat_data. This changes the kernel code to
support either version, by moving over the normal handling
to the 64-bit variant, and adding compatiblity code to handle
the old binary format with the existing ioctl command code.

Fortunately, the command code includes the size of the structure,
so the difference gets handled automatically. In the process of
eliminating the references to 'struct timeval' from the kernel,
I also change the way the timestamp is generated internally,
basically by open-coding the v4l2_get_timestamp() call.

Pull rdma fixes from Doug Ledford:
 "This is our first pull request of the rc cycle. It's not that it's
  been overly quiet, we were just waiting on a few things before sending
  this off.

  For instance, the 6 patch series from Intel for the hfi1 driver had
  actually been pulled in on Tuesday for a Wednesday pull request, only
  to have Jason notice something I missed, so we held off for some
  testing, and then on Thursday had to respin the series because the
  very first patch needed a minor fix (unnecessary cast is all).

  There is a sizable hns patch series in here, as well as a reasonably
  largish hfi1 patch series, then all of the lines of uapi updates are
  just the change to the new official Linux-OpenIB SPDX tag (a bunch of
  our files had what amounts to a BSD-2-Clause + MIT Warranty statement
  as their license as a result of the initial code submission years ago,
  and the SPDX folks decided it was unique enough to warrant a unique
  tag), then the typical mlx4 and mlx5 updates, and finally some cxgb4
  and core/cache/cma updates to round out the bunch.

  None of it was overly large by itself, but in the 2 1/2 weeks we've
  been collecting patches, it has added up :-/.

  As best I can tell, it's been through 0day (I got a notice about my
  last for-next push, but not for my for-rc push, but Jason seems to
  think that failure messages are prioritized and success messages not
  so much). It's also been through linux-next. And yes, we did notice in
  the context portion of the CMA query gid fix patch that there is a
  dubious BUG_ON() in the code, and have plans to audit our BUG_ON usage
  and remove it anywhere we can.

  Summary:

   - Various build fixes (USER_ACCESS=m and ADDR_TRANS turned off)

   - SPDX license tag cleanups (new tag Linux-OpenIB)

   - RoCE GID fixes related to default GIDs

   - Various fixes to: cxgb4, uverbs, cma, iwpm, rxe, hns (big batch),

adafae6229 media: v4l2-core: get rid of videobuf-dvb
Videobuf has been replaced by videobuf2. Now, no drivers use
the videobuf-dvb helper module anymore. So, get rid of it.

For the files written with a copyright with mchehab@s-opensource,
let's keep Samsung on their names, using mchehab+samsung@kernel.org,
in order to keep pointing to my employer, with sponsors the work.

For the files written before I join Samsung (on July, 4 2013),
let's just use mchehab@kernel.org.

8236b0ae31 bdi: wake up concurrent wb_shutdown() callers.
syzbot is reporting hung tasks at wait_on_bit(WB_shutting_down) in
wb_shutdown() [1]. This seems to be because commit 5318ce7d46 ("bdi:
Shutdown writeback on all cgwbs in cgwb_bdi_destroy()") forgot to call
wake_up_bit(WB_shutting_down) after clear_bit(WB_shutting_down).

Introduce a helper function clear_and_wake_up_bit() and use it, in order
to avoid similar errors in future.

30ca22e4a5 ipv6: Revert "ipv6: Allow non-gateway ECMP for IPv6"
This reverts commit edd7ceb782 ("ipv6: Allow non-gateway ECMP for
IPv6").

Eric reported a division by zero in rt6_multipath_rebalance() which is
caused by above commit that considers identical local routes to be
siblings. The division by zero happens because a nexthop weight is not
set for local routes.

Revert the commit as it does not fix a bug and has side effects.

To reproduce:

# ip -6 address add 2001:db8::1/64 dev dummy0
# ip -6 address add 2001:db8::1/64 dev dummy1

c212d2c7fc net/tls: Don't recursively call push_record during tls_write_space callbacks
It is reported that in some cases, write_space may be called in
do_tcp_sendpages, such that we recursively invoke do_tcp_sendpages again:

[  660.468802]  ? do_tcp_sendpages+0x8d/0x580
[  660.468826]  ? tls_push_sg+0x74/0x130 [tls]
[  660.468852]  ? tls_push_record+0x24a/0x390 [tls]
[  660.468880]  ? tls_write_space+0x6a/0x80 [tls]
...

tls_push_sg already does a loop over all sending sg's, so ignore
any tls_write_space notifications until we are done sending.
We then have to call the previous write_space to wake up
poll() waiters after we are done with the send loop.

19b9ad6731 <linux/stringhash.h>: fix end_name_hash() for 64bit long
The comment claims that this helper will try not to loose bits, but for
64bit long it looses the high bits before hashing 64bit long into 32bit
int.  Use the helper hash_long() to do the right thing for 64bit long.
For 32bit long, there is no change.

All the callers of end_name_hash() either assign the result to
qstr->hash, which is u32 or return the result as an int value (e.g.
full_name_hash()).  Change the helper return type to int to conform to
its users.

[ It took me a while to apply this, because my initial reaction to it
  was - incorrectly - that it could make for slower code.

  After having looked more at it, I take back all my complaints about
  the patch, Amir was right and I was mis-reading things or just being
  stupid.

  I also don't worry too much about the possible performance impact of
  this on 64-bit, since most architectures that actually care about
  performance end up not using this very much (the dcache code is the
  most performance-critical, but the word-at-a-time case uses its own
  hashing anyway).

  So this ends up being mostly used for filesystems that do their own
  degraded hashing (usually because they want a case-insensitive
  comparison function).

  A _tiny_ worry remains, in that not everybody uses DCACHE_WORD_ACCESS,
  and then this potentially makes things more expensive on 64-bit
  architectures with slow or lacking multipliers even for the normal
  case.

  That said, realistically the only such architecture I can think of is
  PA-RISC. Nobody really cares about performance on that, it's more of a
  "look ma, I've got warts^W an odd machine" platform.

  So the patch is fine, and all my initial worries were just misplaced
  from not looking at this properly.   - Linus ]

53692908b0 KVM: arm/arm64: vgic: Fix source vcpu issues for GICv2 SGI
Now that we make sure we don't inject multiple instances of the
same GICv2 SGI at the same time, we've made another bug more
obvious:

If we exit with an active SGI, we completely lose track of which
vcpu it came from. On the next entry, we restore it with 0 as a
source, and if that wasn't the right one, too bad. While this
doesn't seem to trouble GIC-400, the architectural model gets
offended and doesn't deactivate the interrupt on EOI.

Another connected issue is that we will happilly make pending
an interrupt from another vcpu, overriding the above zero with
something that is just as inconsistent. Don't do that.

The final issue is that we signal a maintenance interrupt when
no pending interrupts are present in the LR. Assuming we've fixed
the two issues above, we end-up in a situation where we keep
exiting as soon as we've reached the active state, and not be
able to inject the following pending.

The fix comes in 3 parts:
- GICv2 SGIs have their source vcpu saved if they are active on
  exit, and restored on entry
- Multi-SGIs cannot go via the Pending+Active state, as this would
  corrupt the source field
- Multi-SGIs are converted to using MI on EOI instead of NPIE

ed76952072 usb: gadget: composite Allow for larger configuration descriptors
The composite framework allows us to create gadgets composed from many
different functions, which need to fit into a single configuration
descriptor.

Some functions (like uvc) can produce configuration descriptors upwards
of 2500 bytes on their own.

This patch increases the limit from 1024 bytes to 4096.

   header) - and it seems that the code there is so fragile that any
   change in this header will break it. Add a better interface so users
   do not need to change their code every time that header changes.

6082d9c9c9 net/mlx5: Fix mlx5_get_vector_affinity function
Adding the vector offset when calling to mlx5_vector2eqn() is wrong.
This is because mlx5_vector2eqn() checks if EQ index is equal to vector number
and the fact that the internal completion vectors that mlx5 allocates
don't get an EQ index.

The second problem here is that using effective_affinity_mask gives the same
CPU for different vectors.
This leads to unmapped queues when calling it from blk_mq_rdma_map_queues().
This doesn't happen when using affinity_hint mask.

0566e40ce7 tracing: initcall: Ordered comparison of function pointers
Using initcall_t in the __field macro generates the following warning
with clang version 6.0:

include/trace/events/initcall.h:34:3: warning: ordered comparison of
function pointers ('initcall_t' (aka 'int (*)(void)') and 'initcall_t')

__field macro expands to __field_ext macro which does is_signed_type
check on the type argument. Since initcall_t is defined as a function
pointer, using it as the type in the __field macro, leads to an ordered
comparison of function pointer warning, inside the check. Using
__field_struct macro avoids the issue.
