0aab5b914b arm64: dts: renesas: Group tuples in interrupt properties
To improve human readability and enable automatic validation, the tuples
in the various properties containing interrupt specifiers should be
grouped.  While "make dtbs_check" does not impose this yet for the
"interrupts" property, it does for the "interrupt-map" property.

Fix this by grouping the tuples of the "interrupts" and "interrupt-map"
properties using angle brackets.

7fd7d6c504 ALSA: uapi: Fix typos and header inclusion in asound.h
The recent changes in uapi/asoundlib.h caused some build errors in
alsa-lib side because of a typo and the new included files.
Basically asound.h is supposed to be usable also on non-Linux systems,
so we've tried to avoid the Linux-specific include files.

This patch is an attempt to recover from those changes.

4fa406caf9 ALSA: hdspm: Drop linux/types.h inclusion in uapi header
The hdspm.h uapi header has been used also from non-Linux or platforms
that don't have linux/*.h.  It was OK in the past because alsa-lib
contained the modified version of this header file, but now it tries
to the verbatim copy, so it broke the build.  This fixes it again.

d63e63d421 ALSA: hdsp: Make uapi/hdsp.h compilable again
Recently alsa-lib updated its content of sound/hdsp.h just by copying
the latest Linus kernel uapi/*.h, and this broke the build of
alsa-tools programs.  We used to modify the headers so that they can
be built without asoundlib.h and linux kernel headers, and the
verbatim copy doesn't work as is.

This patch removes again the linux/types.h inclusion and drop __user
prefix that broke the build and adjusts the corresponding code.

2e46886763 ALSA: emu10k1: Make uapi/emu10k1.h compilable again
Recently we updated the content in alsa-lib uapi header files by just
copying from the latest Linus kernel uapi/*.h, and noticed that it
broke the build of some alsa-tools programs.  The reason is that we
used to have a modified version in the past, so that the program can
be built without referring to the unexported stuff like
snd_ctl_elem_id or __user prefix.

This patch attempts to restore that, i.e. dropping the stuff that
can't be referred in the user-space.  For adapting the changes in
uapi/emu10k1.h, the emu10k1 driver code is also slightly modified.
Most of changes are pointer cast.

f4eef1b652 xen-blkback: support dynamic unbind/bind
By simply re-attaching to shared rings during connect_ring() rather than
assuming they are freshly allocated (i.e assuming the counters are zero)
it is possible for vbd instances to be unbound and re-bound from and to
(respectively) a running guest.

This has been tested by running:

while true;
  do fio --name=randwrite --ioengine=libaio --iodepth=16 \
  --rw=randwrite --bs=4k --direct=1 --size=1G --verify=crc32;
  done

in a PV guest whilst running:

while true;
  do echo vbd-$DOMID-$VBD >unbind;
  echo unbound;
  sleep 5;
  echo vbd-$DOMID-$VBD >bind;
  echo bound;
  sleep 3;
  done

in dom0 from /sys/bus/xen-backend/drivers/vbd to continuously unbind and
re-bind its system disk image.

This is a highly useful feature for a backend module as it allows it to be
unloaded and re-loaded (i.e. updated) without requiring domUs to be halted.
This was also tested by running:

while true;
  do echo vbd-$DOMID-$VBD >unbind;
  echo unbound;
  sleep 5;
  rmmod xen-blkback;
  echo unloaded;
  sleep 1;
  modprobe xen-blkback;
  echo bound;
  cd $(pwd);
  sleep 3;
  done

in dom0 whilst running the same loop as above in the (single) PV guest.

Some (less stressful) testing has also been done using a Windows HVM guest
with the latest 9.0 PV drivers installed.

1ee54195a3 xen/interface: re-define FRONT/BACK_RING_ATTACH()
Currently these macros are defined to re-initialize a front/back ring
(respectively) to values read from the shared ring in such a way that any
requests/responses that are added to the shared ring whilst the front/back
is detached will be skipped over. This, in general, is not a desirable
semantic since most frontend implementations will eventually block waiting
for a response which would either never appear or never be processed.

Since the macros are currently unused, take this opportunity to re-define
them to re-initialize a front/back ring using specified values. This also
allows FRONT/BACK_RING_INIT() to be re-defined in terms of
FRONT/BACK_RING_ATTACH() using a specified value of 0.

NOTE: BACK_RING_ATTACH() will be used directly in a subsequent patch.

672b7763cb xenbus: limit when state is forced to closed
If a driver probe() fails then leave the xenstore state alone. There is no
reason to modify it as the failure may be due to transient resource
allocation issues and hence a subsequent probe() may succeed.

If the driver supports re-binding then only force state to closed during
remove() only in the case when the toolstack may need to clean up. This can
be detected by checking whether the state in xenstore has been set to
closing prior to device removal.

NOTE: Re-bind support is indicated by new boolean in struct xenbus_driver,
      which defaults to false. Subsequent patches will add support to
      some backend drivers.

c534374ecf xenbus: move xenbus_dev_shutdown() into frontend code...
...and make it static

xenbus_dev_shutdown() is seemingly intended to cause clean shutdown of PV
frontends when a guest is rebooted. Indeed the function waits for a
conpletion which is only set by a call to xenbus_frontend_closed().

This patch removes the shutdown() method from backends and moves
xenbus_dev_shutdown() from xenbus_probe.c into xenbus_probe_frontend.c,
renaming it appropriately and making it static.

NOTE: In the case where the backend is running in a driver domain, the
      toolstack should have already terminated any frontends that may be
      using it (since Xen does not support re-startable PV driver domains)
      so xenbus_dev_shutdown() should never be called.

589b72894f xen/blkfront: Adjust indentation in xlvbd_alloc_gendisk
Clang warns:

../drivers/block/xen-blkfront.c:1117:4: warning: misleading indentation;
statement is not part of the previous 'if' [-Wmisleading-indentation]
                nr_parts = PARTS_PER_DISK;

                if (err)
                ^

This is because there is a space at the beginning of this line; remove
it so that the indentation is consistent according to the Linux kernel
coding style and clang no longer warns.

While we are here, the previous line has some trailing whitespace; clean
that up as well.

This fixes a long-standing bug - we haven't been able to check the
firmware image that was loaded for D3/not-D3 since the introduction
of the unified image...

Fix this by keeping a status flag for D3 instead of checking for

This reduces occurrences of checks for IWL_UCODE_WOWLAN to just the
code that actually loads the image or deals with it in other ways.

as the whole drivers/soc boilerplate for CONFIG_SOC_SIFIVE.

Otherwise the phy state may end up only half initialized, and this can
