aa7b58597f ocfs2: delete redundant code and set the node bit into maybe_map directly
The variable `set_maybe' is redundant when the mle has been found in the
map.  So it is ok to set the node_idx into mle's maybe_map directly.

eb17726b00 m32r: add simple dma
Some builds of m32r were failing as it tried to build few drivers which
needed dma but m32r is not having dma support.  Objections were raised
when it was tried to make those drivers depend on HAS_DMA.  So the next
best thing is to add dma support to m32r.  dma_noop is a very simple dma
with 1:1 memory mapping.

3fb4afd9a5 prctl: remove one-shot limitation for changing exe link
This limitation came with the reason to remove "another way for
malicious code to obscure a compromised program and masquerade as a
benign process" by allowing "security-concious program can use this
prctl once during its early initialization to ensure the prctl cannot
later be abused for this purpose":

    http://marc.info/?l=linux-kernel&m=133160684517468&w=2

This explanation doesn't look sufficient.  The only thing "exe" link is
indicating is the file, used to execve, which is basically nothing and
not reliable immediately after process has returned from execve system
call.

Moreover, to use this feture, all the mappings to previous exe file have
to be unmapped and all the new exe file permissions must be satisfied.

Which means, that changing exe link is very similar to calling execve on
the binary.

The need to remove this limitations comes from migration of NFS mount
point, which is not accessible during restore and replaced by other file
system.  Because of this exe link has to be changed twice.

c0b942a763 kthread: add __printf attributes
When commit fbae2d44aa ("kthread: add kthread_create_worker*()")
introduced some kthread_create_...() functions which were taking
printf-like parametter, it introduced __printf attributes to some
functions (e.g.  kthread_create_worker()).  Nevertheless some new
functions were forgotten (they have been detected thanks to
-Wmissing-format-attribute warning flag).

Add the missing __printf attributes to the newly-introduced functions in
order to detect formatting issues at build-time with -Wformat flag.

0cb80b4847 dax: Fix sleep in atomic contex in grab_mapping_entry()
Commit 642261ac99: "dax: add struct iomap based DAX PMD support" has
introduced unmapping of page tables if huge page needs to be split in
grab_mapping_entry(). However the unmapping happens after
radix_tree_preload() call which disables preemption and thus
unmap_mapping_range() tries to acquire i_mmap_lock in atomic context
which is a bug. Fix the problem by moving unmapping before
radix_tree_preload() call.

db1a0ae214 drm/nouveau/bl: Assign different names to interfaces
Currently, every backlight interface created by Nouveau uses the same name,
nv_backlight. This leads to a sysfs warning as it tries to create an already
existing folder. This patch adds a incremented number to the name, but keeps
the initial name as nv_backlight, to avoid possibly breaking userspace; the
second interface will be named nv_backlight1, and so on.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=86539

v2:
* Switch to using ida for generating unique IDs, as suggested by Ilia Mirkin;
* Allocate backlight name on the stack, as suggested by Ilia Mirkin;
* Move `nouveau_get_backlight_name()` to avoid forward declaration, as
  suggested by Ilia Mirkin;
* Fix reference to bug report formatting, as reported by Nick Tenney.

v3:
* Define a macro for the size of the backlight name, to avoid defining
  it multiple times;
* Use snprintf in place of sprintf.

v4:
* Do not create similarly named interfaces when reaching the maximum
  amount of unique names, but fail instead, as pointed out by Lukas Wunner

10dcab3e7f drm/nouveau/ttm: wait for bo fence to signal before unmapping vmas
TTM was changed a while back to allow for pipelining of buffer moves, and
part of this was the removal of waiting for a BO to idle before calling
move(), placing the responsibility on the driver to do this if required.

That's all well and good, except, we make use of move_notify() to handle
mapping/unmapping from the GPU VMM as move() isn't called on all paths.

This commit adds a wait before unmapping from a VMM in move_notify(), to
prevent GPU page faults where a buffer is still being accessed.

This has been on the TODO list for a while now, recovering from things
such as attempting to execute a push buffer or touch a semaphore in an
unmapped memory area.

The only thing required on the HW side here is that the offending
channel is removed from the runlist, and *not* a full reset of PFIFO.

This used to be a bit messier to handle before the rework to make use
of engine topology info, but is apparently now trivial.

  Since the AMD side already did this, this change also opened up the

default.

Then I run another bisect round and got here with the same backtrace:

995c6a7fd9 ALSA: hiface: Fix M2Tech hiFace driver sampling rate change
Sampling rate changes after first set one are not reflected to the
hardware, while driver and ALSA think the rate has been changed.

Fix the problem by properly stopping the interface at the beginning of
prepare call, allowing new rate to be set to the hardware. This keeps
the hardware in sync with the driver.

0120073091 ALSA: usb-audio: Eliminate noise at the start of DSD playback.
[Problem]
In some USB DACs, a terrible pop noise comes to be heard
at the start of DSD playback (in the following situations).

- play first DSD track
- change from PCM track to DSD track
- change from DSD64 track to DSD128 track (and etc...)
- seek DSD track
- Fast-Forward/Rewind DSD track

[Cause]
At the start of playback, there is a little silence.
The silence bit pattern "0x69" is required on DSD mode,
but it is not like that.

[Solution]
This patch adds DSD silence pattern to the endpoint settings.
