3f9df56480 sound updates for 5.9
This became wide and scattered updates all over the sound tree as
 diffstat shows: lots of (still ongoing) refactoring works in ASoC,
 fixes and cleanups caught by static analysis, inclusive term
 conversions as well as lots of new drivers.  Below are highlights:
 
 ASoC core:
 * API cleanups and conversions to the unified mute_stream() call
 * Simplify I/O helper functions
 * Use helper macros to retrieve RTD from substreams
 
 ASoC drivers:
 * Lots of fixes and cleanups in Intel ASoC drivers
 * Lots of new stuff: Freescale MQS and i.MX6sx, Intel KeemBay I2S,
   Maxim MAX98360A and MAX98373 SoundWire, various Mediatek boards,
   nVidia Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries
   boards, TI J721e EVM
 
 ALSA core:
 * Minor code refacotring for SG-buffer handling
 
 HD-audio:
 * Generalization of mute-LED handling with LED classdev
 * Intel silent stream support for HDMI
 * Device-specific fixes: CA0132, Loongson-3
 
 Others:
 * Usual USB- and HD-audio quirks for various devices
 * Fixes for echoaudio DMA position handling
 * Various documents and trivial fixes for sparse warnings
 * Conversion to adapt inclusive terms

7b4ea9456d Revert "x86/mm/64: Do not sync vmalloc/ioremap mappings"
This reverts commit 8bb9bf242d.

It seems the vmalloc page tables aren't always preallocated in all
situations, because Jason Donenfeld reports an oops with this commit:

  BUG: unable to handle page fault for address: ffffe8ffffd00608
  #PF: supervisor read access in kernel mode
  #PF: error_code(0x0000) - not-present page
  PGD 0 P4D 0

   ret_from_fork+0x1f/0x30
  CR2: ffffe8ffffd00608

and that page fault address is right in that vmalloc space, and we
clearly don't have a PGD/P4D entry for it.

Looking at the "Code:" line, the actual fault seems to come from the
'pwq->wq' dereference at the top of the process_one_work() function:

        struct pool_workqueue *pwq = get_work_pwq(work);
        struct worker_pool *pool = worker->pool;
        bool cpu_intensive = pwq->wq->flags & WQ_CPU_INTENSIVE;

so 'struct pool_workqueue *pwq' is the allocation that hasn't been
synchronized across CPUs.

Just revert for now, while Joerg figures out the cause.

6d2b84a4e5 This tree adds the sched_set_fifo*() encapsulation APIs to remove
static priority level knowledge from non-scheduler code.
 
 The three APIs for non-scheduler code to set SCHED_FIFO are:
 
  - sched_set_fifo()
  - sched_set_fifo_low()
  - sched_set_normal()
 
 These are two FIFO priority levels: default (high), and a 'low' priority level,
 plus sched_set_normal() to set the policy back to non-SCHED_FIFO.
 
 Since the changes affect a lot of non-scheduler code, we kept this in a separate
 tree.
 
 When merging to the latest upstream tree there's a conflict in drivers/spi/spi.c,
 which can be resolved via:
 
 	sched_set_fifo(ctlr->kworker_task);

055923bf6b fs: dlm: implement tcp graceful shutdown
During my code inspection I saw there is no implementation of a graceful
shutdown for tcp. This patch will introduce a graceful shutdown for tcp
connections. The shutdown is implemented synchronized as
dlm_lowcomms_stop() is called to end all dlm communication. After shutdown
is done, a lot of flush and closing functionality will be called. However
I don't see a problem with that.

The waitqueue for synchronize the shutdown has a timeout of 10 seconds, if
timeout a force close will be exectued.

ba3ab3ca68 fs: dlm: change handling of reconnects
This patch changes the handling of reconnects. At first we only close
the connection related to the communication failure. If we get a new
connection for an already existing connection we close the existing
connection and take the new one.

This patch improves significantly the stability of tcp connections while
running "tcpkill -9 -i $IFACE port 21064" while generating a lot of dlm
messages e.g. on a gfs2 mount with many files. My test setup shows that a
deadlock is "more" unlikely. Before this patch I wasn't able to get
not a deadlock after 5 seconds. After this patch my observation is
that it's more likely to survive after 5 seconds and more, but still a
deadlock occurs after certain time. My guess is that there are still
"segments" inside the tcp writequeue or retransmit queue which get dropped
when receiving a tcp reset [1]. Hard to reproduce because the right message
need to be inside these queues, which might even be in the 5 first seconds
with this patch.

This patch doesn't close sockets when there is an invalid dlm message
received. The connection will probably reconnect anyway so. To not
close the connection will reduce the number of possible failtures.
As we don't have a different strategy to react on such scenario
just keep going the connection and ignore the message.

0cd39f4600 locking/seqlock, headers: Untangle the spaghetti monster
By using lockdep_assert_*() from seqlock.h, the spaghetti monster
attacked.

Attack back by reducing seqlock.h dependencies from two key high level headers:

 - <linux/seqlock.h>:               -Remove <linux/ww_mutex.h>
 - <linux/time.h>:                  -Remove <linux/seqlock.h>
 - <linux/sched.h>:                 +Add    <linux/seqlock.h>

The price was to add it to sched.h ...

Core header fallout, we add direct header dependencies instead of gaining them
parasitically from higher level headers:

 - <linux/dynamic_queue_limits.h>:  +Add <asm/bug.h>
 - <linux/hrtimer.h>:               +Add <linux/seqlock.h>
 - <linux/ktime.h>:                 +Add <asm/bug.h>
 - <linux/lockdep.h>:               +Add <linux/smp.h>
 - <linux/sched.h>:                 +Add <linux/seqlock.h>
 - <linux/videodev2.h>:             +Add <linux/kernel.h>

Arch headers fallout:

 - PARISC: <asm/timex.h>:           +Add <asm/special_insns.h>
 - SH:     <asm/io.h>:              +Add <asm/page.h>
 - SPARC:  <asm/timer_64.h>:        +Add <uapi/asm/asi.h>
 - SPARC:  <asm/vvar.h>:            +Add <asm/processor.h>, <asm/barrier.h>
                                    -Remove <linux/seqlock.h>
 - X86:    <asm/fixmap.h>:          +Add <asm/pgtable_types.h>
                                    -Remove <asm/acpi.h>

There's also a bunch of parasitic header dependency fallout in .c files, not listed
separately.

We want to remove the #include <asm/io.h> from <asm/smp.h>, but for this
we have to move the XTP bits into a separate header first (as these bits
rely on <asm/io.h> definitions), and include them in the .c files that rely
on those APIs.

f45882cfb1 media: camss: fix memory leaks on error handling paths in probe
camss_probe() does not free camss on error handling paths. The patch
introduces an additional error label for this purpose. Besides, it
removes call of v4l2_async_notifier_cleanup() from
camss_of_parse_ports() since its caller, camss_probe(), cleans up all
its resources itself.

In case of errors vpif_probe_complete() releases memory for vpif_obj.sd
and unregisters the V4L2 device. But then this is done again by
vpif_probe() itself. The patch removes the cleaning from
vpif_probe_complete().

04320b3ef9 media: allegro: fix potential null dereference on header
The pointer header is an alias to msg and msg is being null checked.
However, if msg is null then header is also null and this can lead to
a null pointer dereference on the assignment type = header->type. Fix
this just using header->type after the null check and removing the need
for type as it is only used once.

e3083c3f36 media: cafe-driver: use generic power management
Drivers using legacy PM have to manage PCI states and device's PM states
themselves. They also need to take care of configuration registers.

With improved and powerful support of generic PM, PCI Core takes care of
above mentioned, device-independent, jobs.

This driver makes use of PCI helper functions like
pci_save/restore_state() and pci_enable/disable_device() to do required
operations. In generic mode, they are no longer needed.

Change function parameter in both .suspend() and .resume() to
"struct device*" type.

Compile-tested only.

The .suspend() and .resume() callbacks are not defined for this driver.
Still, their power management structure follows the legacy framework. To
bring it under the generic framework, simply remove the binding of
callbacks from struct "pci_driver".

e4a7b2dc35 LEDs changes for 5.9-rc1.
Okay, so... this one is interesting. RGB LEDs are very common, and we
 need to have some kind of support for them. Multicolor is for
 arbitrary set of LEDs in one package, RGB is for LEDs that can produce
 full range of colors. We do not have real multicolor LED that is not

Pull LED updates from Pavel Machek:
 "Okay, so... this one is interesting. RGB LEDs are very common, and we
  need to have some kind of support for them. Multicolor is for
  arbitrary set of LEDs in one package, RGB is for LEDs that can produce
  full range of colors. We do not have real multicolor LED that is not
  RGB in the pipeline, so that one is disabled for now.

This problem is resolved by moving the call to mutex_init() up earlier
in nicvf_probe().

Oliver Neukum says:

====================
misc bug fixes for the hso driver

1. Code reuse led to an unregistration of a net driver that has not been
registered
2. The kernel complains generically if kmalloc with GFP_KERNEL fails
3. A race that can lead to an URB that is in use being reused or
a use after free

abaf00ff04 usb: hso: remove bogus check for EINPROGRESS
This check an inherent race. It opens a race where
an error code has already been set or cleared yet
the URB has not been given back. We cannot do
such an optimization and must unlink unconditionally.

5fcfb6d0bf hso: fix bailout in error case of probe
The driver tries to reuse code for disconnect in case
of a failed probe.
If resources need to be freed after an error in probe, the
netdev must not be freed because it has never been registered.
Fix it by telling the helper which path we are in.

23fcc7dee2 RDMA/mlx5: Fix flow destination setting for RDMA TX flow table
For RDMA TX flow table, set destination type to be 'port' and prevent
creation of flows with TIR destination.

As RDMA TX is an egress flow table the rules on this flow table should
not forward traffic back to the NIC and should set the destination to be
the port.

Without the setting of this destination type flow rules on the RDMA TX
flow tables are not created as FW invokes a syndrome for undefined
destination for the rule.

Fixes: 24670b1a31 ("net/mlx5: Add support for RDMA TX steering")
