Like the DJM-750, ensure that the format control message is passed to
the device when opening a stream. It seems as though fmt->sync_ep is not
always set when this function is called hence the passing of the value
at the call site. If this can be fixed, fmt->sync_up should be used as
the wvalue.
There doesn't seem to be a "cpu_to_le24" type function defined hence for
the open code but I did see a similar thing done in Bluez lib. Perhaps
we can get these definitions defined in byteorder.h. See hci_cpu_to_le24
in include/net/bluetooth/hci.h:2543 for similar usage.

This change adds audio jack injection feature through debugfs, with
this feature, we could validate alsa userspace changes by injecting
plugin or plugout events to the non-phantom audio jacks.
With this change, the sound core will build the folders
$debugfs_mount_dir/sound/cardN if SND_DEBUG and DEBUG_FS are enabled.
And if users also enable the SND_JACK_INJECTION_DEBUG, the jack
injection nodes will be built in the folder cardN like below:
$tree $debugfs_mount_dir/sound

The nodes kctl_id, mask_bits, status and type are read-only, users
could check jack or jack_kctl's information through them.
The nodes sw_inject_enable and jackin_inject are directly used for
injection. The sw_inject_enable is read-write, users could check if
software injection is enabled or not on this jack, and users could
echo 1 or 0 to enable or disable software injection on this jack. Once
the injection is enabled, the jack will not change by hardware events
anymore, once the injection is disabled, the jack will restore the
last reported hardware events to the jack. The jackin_inject is
write-only, if the injection is enabled, users could echo 1 or 0 to
this node to inject plugin or plugout events to this jack.
For the detailed usage information on these nodes, please refer to
Documentation/sound/designs/jack-injection.rst.

Output loopback is a feature where you can record what you hear.
The HDSP series of the RME interfaces provides this functionality
at the hardware level and this patch exposes controls to enable or
disable it per output (playback) channel.
This probably works on other cards but due to a lack of hardware
it is only tested and enabled for the HDSP9632 card with this patch.
Should this patch be accepted a separate patch will be posted to
https://github.com/alsa-project/alsa-tools/tree/master/hdspmixer
which adds "LPBK" buttons to each output in the playback strip for
the user to be able to control this feature from the user land.
Users from Windows tool TotalMixFX should be familiar with this.

Drivers in ALSA firewire stack supports eventing to userspace
applications via ALSA hwdep interface. All of the drivers supports stream
lock events. Some of them supports their unique events according to
specification of target device.
ALSA bebob driver supports the stream lock event only. In the case, it's
enough to check condition only in loop with process blocking. However,
current implementation check it again after breaking the loop.
This commit removes the redundant check.

At probing a UAC2/UAC3 device like NUX MG-300 USB interface, we get
error messages "RANGE setting not yet supported". It comes the place
where the driver tries to determine the resolution of mixer volumes
via SET_CUR_RES and GET_CUR_RES verbs. Those verbs aren't supported
on UAC2 and UAC3, hence the driver warns like the above. Although the
driver handles this error and works as expected, it's still ugly to
show such errors unnecessarily.
This patch papers over the errors by applying the resolution detection
only for UAC1 and skipping it for UAC2/UAC3.

The current USB-audio driver gets an error at probing NUX MG-300 about
parsing the clocks. This is because the firmware doesn't return the
proper connection of the clock selector that is connected to a single
clock; it's likely that the firmware was lazy^w optimized and the
inquiry wasn't handled. Actually it makes little sense to inquire and
set up the single connection explicitly.
This patch fixes the issue by simply skipping the clock selector
inquiry if it's a single connection.

For addressing the regression on Pioneer devices, we recently
corrected the quirk code to enable the implicit feedback mode on those
devices properly. However, the devices still showed problems with the
full duplex operations with JACK, and after debug sessions, we figured
out that the older kernels that had worked with JACK also didn't use
the implicit feedback mode at all although they had the quirk code to
enable it; instead, the old code worked just to skip the normal sync
endpoint setup that would have been detected without it. IOW, what
broke without the implicit-fb quirk in the past was the application of
the normal sync endpoint that is actually the capture data endpoint on
these devices.
This patch covers the overseen piece: it modifies the quirk code again
not to enable the implicit feedback mode but just to make the driver
skipping the sync endpoint detection. This made the driver working
with JACK full-duplex mode again.
Still it's not quite clear why the implicit feedback doesn't work on
those devices yet; maybe it's about some issues in the URB setup. But
at least, with this patch, the driver should work in the level of the
older kernels again.

The UAC2/3 sample rate setup is based on the clock node, which is
usually shared in the interface, and can't be re-setup without
deselecting the interface once, and that's how the current code
behaves. OTOH, the sample rate setup of UAC1 is per endpoint, hence
we basically need to call for each endpoint usage even if those share
the same interface.
This patch fixes the behavior of UAC1 to call always
snd_usb_init_sample_rate() in snd_usb_endpoint_configure().
Fixes: bf6313a0ff ("ALSA: usb-audio: Refactor endpoint management")

Signed-off-by: Takashi Iwai <tiwai@suse.de>
The current sample rate setup function for UAC1 assumes only the first
endpoint retrieved from the interface:altset pair, but the rate set up
may be needed also for the secondary endpoint. Also, retrieving the
endpoint number from the interface descriptor is redundant; we have
already the target endpoint in the given audioformat object.
This patch simplifies the code and corrects the target endpoint as
described in the above. It simply refers to fmt->endpoint directly.
Also, this patch drops the pioneer_djm_set_format_quirk() that is
caleld from snd_usb_set_format_quirk(); this function does the sample
rate setup but for the capture endpoint (0x82), and that's exactly
what the change above fixes.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

So technically there is nothing wrong with adding a pinned page to the
swap cache, but the pinning obviously means that the page can't actually
be free'd right now anyway, so it's a bit pointless.
However, the real problem is not with it being a bit pointless: the real
issue is that after we've added it to the swap cache, we'll try to unmap
the page. That will succeed, because the code in mm/rmap.c doesn't know
or care about pinned pages.
Even the unmapping isn't fatal per se, since the page will stay around
in memory due to the pinning, and we do hold the connection to it using
the swap cache. But when we then touch it next and take a page fault,
the logic in do_swap_page() will map it back into the process as a
possibly read-only page, and we'll then break the page association on
the next COW fault.
Honestly, this issue could have been fixed in any of those other places:
(a) we could refuse to unmap a pinned page (which makes conceptual
sense), or (b) we could make sure to re-map a pinned page writably in
do_swap_page(), or (c) we could just make do_wp_page() not COW the
pinned page (which was what we historically did before that "mm:
do_wp_page() simplification" commit).
But while all of them are equally valid models for breaking this chain,
not putting pinned pages into the swap cache in the first place is the
simplest one by far.
It's also the safest one: the reason why do_wp_page() was changed in the
first place was that getting the "can I re-use this page" wrong is so
fraught with errors. If you do it wrong, you end up with an incorrectly
shared page.
As a result, using "page_maybe_dma_pinned()" in either do_wp_page() or
do_swap_page() would be a serious bug since it is only a (very good)
heuristic. Re-using the page requires a hard black-and-white rule with
no room for ambiguity.
In contrast, saying "this page is very likely dma pinned, so let's not
add it to the swap cache and try to unmap it" is an obviously safe thing
to do, and if the heuristic might very rarely be a false positive, no

Turning a pinned page read-only breaks the pinning after COW. Don't do it.
The whole "track page soft dirty" state doesn't work with pinned pages
anyway, since the page might be dirtied by the pinning entity without
ever being noticed in the page tables.

Turning page table entries read-only requires the mmap_sem held for
writing.
So stop doing the odd games with turning things from read locks to write
locks and back. Just get the write lock.

Linux kernel can only map 1GB of address space for RV32 as the page offset
is set to 0xC0000000. The current description in the Kconfig is confusing
as it indicates that RV32 can support 2GB of physical memory. That is
simply not true for current kernel. In future, a 2GB split support can be
added to allow 2GB physical address space.

Currently, linux kernel can not use last 4k bytes of addressable space
because IS_ERR_VALUE macro treats those as an error. This will be an issue
for RV32 as any memblock allocator potentially allocate chunk of memory
from the end of DRAM (2GB) leading bad address error even though the
address was technically valid.
Fix this issue by limiting the memblock if available memory spans the
entire address space.

If we enter with requests pending and performm cancelations, we'll have
a different inflight count before and after calling prepare_to_wait().
This causes the loop to restart. If we actually ended up canceling
everything, or everything completed in-between, then we'll break out
of the loop without calling finish_wait() on the waitqueue. This can
trigger a warning on exit_signals(), as we leave the task state in
TASK_UNINTERRUPTIBLE.
Put a finish_wait() after the loop to catch that case.

Merge tag '5.11-rc3-smb3' of git://git.samba.org/sfrench/cifs-2.6
Pull cifs fixes from Steve French:
"Two small cifs fixes for stable (including an important handle leak
fix) and three small cleanup patches"
* tag '5.11-rc3-smb3' of git://git.samba.org/sfrench/cifs-2.6:
cifs: style: replace one-element array with flexible-array
cifs: connect: style: Simplify bool comparison
fs: cifs: remove unneeded variable in smb3_fs_context_dup
cifs: fix interrupted close commands
cifs: check pointer before freeing
- Set the minimum GCC version to 5.1 for arm64 due to earlier compiler
bugs.
- Make atomic helpers __always_inline to avoid a section mismatch when
compiling with clang.
- Fix the CMA and crashkernel reservations to use ZONE_DMA (remove the
arm64_dma32_phys_limit variable, no longer needed with a dynamic
ZONE_DMA sizing in 5.11).
- Remove redundant IRQ flag tracing that was leaving lockdep
inconsistent with the hardware state.
- Revert perf events based hard lockup detector that was causing
smp_processor_id() to be called in preemptible context.
- Some trivial cleanups - spelling fix, renaming S_FRAME_SIZE to
PT_REGS_SIZE, function prototypes added.

Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
- Set the minimum GCC version to 5.1 for arm64 due to earlier compiler
bugs.
- Make atomic helpers __always_inline to avoid a section mismatch when
compiling with clang.
- Fix the CMA and crashkernel reservations to use ZONE_DMA (remove the

* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: selftests: Fix spelling of 'Mismatch'
arm64: syscall: include prototype for EL0 SVC functions
compiler.h: Raise minimum version of GCC to 5.1 for arm64
arm64: make atomic helpers __always_inline
arm64: rename S_FRAME_SIZE to PT_REGS_SIZE
Revert "arm64: Enable perf events based hard lockup detector"
arm64: entry: remove redundant IRQ flag tracing
arm64: Remove arm64_dma32_phys_limit and its uses
When 'perf inject' reads a perf.data file from an older version of perf,
it writes event attributes into the output with the original size field,
but lays them out as if they had the size currently used. Readers see a
corrupt file. Update the size field to match the layout.
