Adds two helper macros:
V4L2_FIELD_IS_SEQUENTIAL: returns true if the given field type is
'sequential', that is a full frame is transmitted, or exists in
memory, as all top field lines followed by all bottom field lines,
or vice-versa.
V4L2_FIELD_IS_INTERLACED: returns true if the given field type is
'interlaced', that is a full frame is transmitted, or exists in
memory, as top field lines interlaced with bottom field lines.

V4L2_BUF_TYPE_META_OUTPUT was added by commit 72148d1a57e7
("media: v4l: Add support for V4L2_BUF_TYPE_META_OUTPUT") but the patch
missed adding the type to the macro telling whether a given type is an
output type or not. Do that now. Getting this wrong leads to handling the
buffer as a capture buffer in a lot of places.

We want to be able to uniquely identify buffers for stateless
codecs. The internal timestamp (a u64) as stored internally in the
kernel is a suitable candidate for that, but in struct v4l2_buffer
it is represented as a struct timeval.
Add a v4l2_timeval_to_ns() function that converts the struct timeval
into a u64 in the same way that the kernel does. This makes it possible
to use this u64 elsewhere as a unique identifier of the buffer.
Since timestamps are also copied from the output buffer to the
corresponding capture buffer(s) by M2M devices, the u64 can be
used to refer to both output and capture buffers.
The plan is that in the future we redesign struct v4l2_buffer and use
u64 for the timestamp instead of a struct timeval (which has lots of
problems with 32 vs 64 bit and y2038 layout changes), and then there
is no more need to use this function.

Pull io_uring IO interface from Jens Axboe:
"Second attempt at adding the io_uring interface.
Since the first one, we've added basic unit testing of the three
system calls, that resides in liburing like the other unit tests that
we have so far. It'll take a while to get full coverage of it, but
we're working towards it. I've also added two basic test programs to
tools/io_uring. One uses the raw interface and has support for all the
various features that io_uring supports outside of standard IO, like
fixed files, fixed IO buffers, and polled IO. The other uses the
liburing API, and is a simplified version of cp(1).
This adds support for a new IO interface, io_uring.
io_uring allows an application to communicate with the kernel through
two rings, the submission queue (SQ) and completion queue (CQ) ring.
This allows for very efficient handling of IOs, see the v5 posting for
some basic numbers:
https://lore.kernel.org/linux-block/20190116175003.17880-1-axboe@kernel.dk/
Outside of just efficiency, the interface is also flexible and
extendable, and allows for future use cases like the upcoming NVMe
key-value store API, networked IO, and so on. It also supports async
buffered IO, something that we've always failed to support in the
kernel.
Outside of basic IO features, it supports async polled IO as well.
This particular feature has already been tested at Facebook months ago
for flash storage boxes, with 25-33% improvements. It makes polled IO
actually useful for real world use cases, where even basic flash sees
a nice win in terms of efficiency, latency, and performance. These
boxes were IOPS bound before, now they are not.
This series adds three new system calls. One for setting up an
io_uring instance (io_uring_setup(2)), one for submitting/completing
IO (io_uring_enter(2)), and one for aux functions like registrating
file sets, buffers, etc (io_uring_register(2)). Through the help of
Arnd, I've coordinated the syscall numbers so merge on that front
should be painless.
Jon did a writeup of the interface a while back, which (except for
minor details that have been tweaked) is still accurate. Find that
here:
https://lwn.net/Articles/776703/
Huge thanks to Al Viro for helping getting the reference cycle code
correct, and to Jann Horn for his extensive reviews focused on both
security and bugs in general.
There's a userspace library that provides basic functionality for
applications that don't need or want to care about how to fiddle with
the rings directly. It has helpers to allow applications to easily set
up an io_uring instance, and submit/complete IO through it without
knowing about the intricacies of the rings. It also includes man pages
(thanks to Jeff Moyer), and will continue to grow support helper
functions and features as time progresses. Find it here:

This is basically a direct port of bfe4037e722e, which implements a
one-shot poll command through aio. Description below is based on that
commit as well. However, instead of adding a POLL command and relying
on io_cancel(2) to remove it, we mimic the epoll(2) interface of
having a command to add a poll notification, IORING_OP_POLL_ADD,
and one to remove it again, IORING_OP_POLL_REMOVE.
To poll for a file descriptor the application should submit an sqe of
type IORING_OP_POLL. It will poll the fd for the events specified in the
poll_events field.
Unlike poll or epoll without EPOLLONESHOT this interface always works in
one shot mode, that is once the sqe is completed, it will have to be
resubmitted.

This enables an application to do IO, without ever entering the kernel.
By using the SQ ring to fill in new sqes and watching for completions
on the CQ ring, we can submit and reap IOs without doing a single system
call. The kernel side thread will poll for new submissions, and in case
of HIPRI/polled IO, it'll also poll for completions.
By default, we allow 1 second of active spinning. This can by changed
by passing in a different grace period at io_uring_register(2) time.
If the thread exceeds this idle time without having any work to do, it
will set:
sq_ring->flags |= IORING_SQ_NEED_WAKEUP.
The application will have to call io_uring_enter() to start things back
up again. If IO is kept busy, that will never be needed. Basically an
application that has this feature enabled will guard it's
io_uring_enter(2) call with:
read_barrier();
if (*sq_ring->flags & IORING_SQ_NEED_WAKEUP)
io_uring_enter(fd, 0, 0, IORING_ENTER_SQ_WAKEUP);
instead of calling it unconditionally.
It's mandatory to use fixed files with this feature. Failure to do so
will result in the application getting an -EBADF CQ entry when
submitting IO.

We normally have to fget/fput for each IO we do on a file. Even with
the batching we do, the cost of the atomic inc/dec of the file usage
count adds up.
This adds IORING_REGISTER_FILES, and IORING_UNREGISTER_FILES opcodes
for the io_uring_register(2) system call. The arguments passed in must
be an array of __s32 holding file descriptors, and nr_args should hold
the number of file descriptors the application wishes to pin for the
duration of the io_uring instance (or until IORING_UNREGISTER_FILES is
called).
When used, the application must set IOSQE_FIXED_FILE in the sqe->flags
member. Then, instead of setting sqe->fd to the real fd, it sets sqe->fd
to the index in the array passed in to IORING_REGISTER_FILES.
Files are automatically unregistered when the io_uring instance is torn
down. An application need only unregister if it wishes to register a new
set of fds.

If we have fixed user buffers, we can map them into the kernel when we
setup the io_uring. That avoids the need to do get_user_pages() for
each and every IO.
To utilize this feature, the application must call io_uring_register()
after having setup an io_uring instance, passing in
IORING_REGISTER_BUFFERS as the opcode. The argument must be a pointer to
an iovec array, and the nr_args should contain how many iovecs the
application wishes to map.
If successful, these buffers are now mapped into the kernel, eligible
for IO. To use these fixed buffers, the application must use the
IORING_OP_READ_FIXED and IORING_OP_WRITE_FIXED opcodes, and then
set sqe->index to the desired buffer index. sqe->addr..sqe->addr+seq->len
must point to somewhere inside the indexed buffer.
The application may register buffers throughout the lifetime of the
io_uring instance. It can call io_uring_register() with
IORING_UNREGISTER_BUFFERS as the opcode to unregister the current set of
buffers, and then register a new set. The application need not
unregister buffers explicitly before shutting down the io_uring
instance.
It's perfectly valid to setup a larger buffer, and then sometimes only
use parts of it for an IO. As long as the range is within the originally
mapped region, it will work just fine.
For now, buffers must not be file backed. If file backed buffers are
passed in, the registration will fail with -1/EOPNOTSUPP. This
restriction may be relaxed in the future.
RLIMIT_MEMLOCK is used to check how much memory we can pin. A somewhat
arbitrary 1G per buffer size is also imposed.

Add support for a polled io_uring instance. When a read or write is
submitted to a polled io_uring, the application must poll for
completions on the CQ ring through io_uring_enter(2). Polled IO may not
generate IRQ completions, hence they need to be actively found by the
application itself.
To use polling, io_uring_setup() must be used with the
IORING_SETUP_IOPOLL flag being set. It is illegal to mix and match
polled and non-polled IO on an io_uring.

The submission queue (SQ) and completion queue (CQ) rings are shared
between the application and the kernel. This eliminates the need to
copy data back and forth to submit and complete IO.
IO submissions use the io_uring_sqe data structure, and completions
are generated in the form of io_uring_cqe data structures. The SQ
ring is an index into the io_uring_sqe array, which makes it possible
to submit a batch of IOs without them being contiguous in the ring.
The CQ ring is always contiguous, as completion events are inherently
unordered, and hence any io_uring_cqe entry can point back to an
arbitrary submission.
Two new system calls are added for this:
io_uring_setup(entries, params)
Sets up an io_uring instance for doing async IO. On success,
returns a file descriptor that the application can mmap to
gain access to the SQ ring, CQ ring, and io_uring_sqes.
io_uring_enter(fd, to_submit, min_complete, flags, sigset, sigsetsize)
Initiates IO against the rings mapped to this fd, or waits for
them to complete, or both. The behavior is controlled by the
parameters passed in. If 'to_submit' is non-zero, then we'll
try and submit new IO. If IORING_ENTER_GETEVENTS is set, the
kernel will wait for 'min_complete' events, if they aren't
already available. It's valid to set IORING_ENTER_GETEVENTS
and 'min_complete' == 0 at the same time, this allows the
kernel to return already completed events without waiting
for them. This is useful only for polling, as for IRQ
driven IO, the application can just check the CQ ring
without entering the kernel.
With this setup, it's possible to do async IO with a single system
call. Future developments will enable polled IO with this interface,
and polled submission as well. The latter will enable an application
to do IO without doing ANY system calls at all.
For IRQ driven IO, an application only needs to enter the kernel for
completions if it wants to wait for them to occur.
Each io_uring is backed by a workqueue, to support buffered async IO
as well. We will only punt to an async context if the command would
need to wait for IO on the device side. Any data that can be accessed
directly in the page cache is done inline. This avoids the slowness
issue of usual threadpools, since cached data is accessed as quickly
as a sync interface.

Pull block layer updates from Jens Axboe:
"Not a huge amount of changes in this round, the biggest one is that we
finally have Mings multi-page bvec support merged. Apart from that,
this pull request contains:
- Small series that avoids quiescing the queue for sysfs changes that
match what we currently have (Aleksei)
- Series of bcache fixes (via Coly)
- Series of lightnvm fixes (via Mathias)
- NVMe pull request from Christoph. Nothing major, just SPDX/license
cleanups, RR mp policy (Hannes), and little fixes (Bart,
Chaitanya).
- BFQ series (Paolo)
- Save blk-mq cpu -> hw queue mapping, removing a pointer indirection
for the fast path (Jianchao)
- fops->iopoll() added for async IO polling, this is a feature that
the upcoming io_uring interface will use (Christoph, me)
- Partition scan loop fixes (Dongli)
- mtip32xx conversion from managed resource API (Christoph)
- cdrom registration race fix (Guenter)
- MD pull from Song, two minor fixes.
- Various documentation fixes (Marcos)
- Multi-page bvec feature. This brings a lot of nice improvements
with it, like more efficient splitting, larger IOs can be supported
without growing the bvec table size, and so on. (Ming)
- Various little fixes to core and drivers"

Given a master fd we can then override the priority of the context
in another fd.
Using these overrides was recommended by Christian instead of trying
to submit from a master fd, and I am adding a way to override a
single context instead of the entire process so we can only upgrade
a single Vulkan queue and not effectively the entire process.
Reused the flags field as it was checked to be 0 anyways, so nothing
used it. This is source-incompatible (due to the name change), but
ABI compatible.

This add an ioctl to migrate a range of process address space to the
device memory. On platform without cache coherent bus (x86, ARM, ...)
this means that CPU can not access that range directly, instead CPU
will fault which will migrate the memory back to system memory.
This is behind a staging flag so that we can evolve the API.

This uses HMM to mirror a process' CPU page tables into a channel's page
tables, and keep them synchronised so that both the CPU and GPU are able
to access the same memory at the same virtual address.
While this code also supports Volta/Turing, it's only enabled for Pascal
GPUs currently due to channel recovery being unreliable right now on the
later GPUs.

New chunk for dependency on start of job's execution instead on
the end. This is used for GPU deadlock prevention when
userspace uses mid-IB fences to wait for mid-IB work on other rings.
v2: Fix typo in AMDGPU_CHUNK_ID_SCHEDULED_DEPENDENCIES
v3: Bump KMS version
v4: put old fence AFTER acquiring the scheduled fence.

We want to allow userspace to reconfigure the subslice configuration on a
per context basis.
This is required for the functional requirement of shutting down non-VME
enabled sub-slices on Gen11 parts.
To do so, we expose a context parameter to allow adjustment of the RPCS
register stored within the context image (and currently not accessible via
LRI).
If the context is adjusted before first use or whilst idle, the adjustment
is for "free"; otherwise if the context is active we queue a request to do
so (using the kernel context), following all other activity by that
context, which is also marked as barrier for all following submission
against the same context.
Since the overhead of device re-configuration during context switching can
be significant, especially in multi-context workloads, we limit this new
uAPI to only support the Gen11 VME use case. In this use case either the
device is fully enabled, and exactly one slice and half of the subslices
are enabled.
Example usage:
struct drm_i915_gem_context_param_sseu sseu = { };
struct drm_i915_gem_context_param arg = {
.param = I915_CONTEXT_PARAM_SSEU,
.ctx_id = gem_context_create(fd),
.size = sizeof(sseu),
.value = to_user_pointer(&sseu)
};
/* Query device defaults. */
gem_context_get_param(fd, &arg);
/* Set VME configuration on a 1x6x8 part. */
sseu.slice_mask = 0x1;
sseu.subslice_mask = 0xe0;
gem_context_set_param(fd, &arg);
v2: Fix offset of CTX_R_PWR_CLK_STATE in intel_lr_context_set_sseu()
(Lionel)
v3: Add ability to program this per engine (Chris)
v4: Move most get_sseu() into i915_gem_context.c (Lionel)
v5: Validate sseu configuration against the device's capabilities (Lionel)
v6: Change context powergating settings through MI_SDM on kernel context
(Chris)
v7: Synchronize the requests following a powergating setting change using
a global dependency (Chris)
Iterate timelines through dev_priv.gt.active_rings (Tvrtko)

(Lionel/Tvrtko)
v8: s/union intel_sseu/struct intel_sseu/ (Lionel)
s/dev_priv/i915/ (Tvrtko)
Change uapi class/instance fields to u16 (Tvrtko)
Bump mask fields to 64bits (Lionel)
Don't return EPERM when dynamic sseu is disabled (Tvrtko)
v9: Import context image into kernel context's ppgtt only when
reconfiguring powergated slice/subslices (Chris)
Use aliasing ppgtt when needed (Michel)

Right now, userspace doesn't do any L2T writes, but we should lay out
our expectations for how it works.
v2: Explicitly mention the VCD cache flushing requirements and that
we'll flush the other caches before each of the CLs.

Large enterprise clients often run applications out of networked file
systems where the IT mandated layout of project volumes can end up
leading to paths that are longer than 128 characters. Bumping this up
to the next order of two solves this problem in all but the most
egregious case while still fitting into a 512b slab.

Add an autofs file system mount option that can be used to provide a
generic indicator to applications that the mount entry should be ignored
when displaying mount information.
In other OSes that provide autofs and that provide a mount list to user
space based on the kernel mount list a no-op mount option ("ignore" is
the one use on the most common OS) is allowed so that autofs file system
users can optionally use it.
The idea is that it be used by user space programs to exclude autofs
mounts from consideration when reading the mounts list.
Prior to the change to link /etc/mtab to /proc/self/mounts all I needed
to do to achieve this was to use mount(2) and not update the mtab but
now that no longer works.
I know the symlinking happened a long time ago and I considered doing
this then but, at the time I couldn't remember the commonly used option
name and thought persuading the various utility maintainers would be too
hard.
But now I have a RHEL request to do this for compatibility for a widely
used product so I want to go ahead with it and try and enlist the help
of some utility package maintainers.
Clearly, without the option nothing can be done so it's at least a
start.

<linux/kernel.h> tends to be cluttered because we often put various sort
of unrelated stuff in it. So, we have split out a sensible chunk of
code into a separate header from time to time.
This commit splits out the *_MAX and *_MIN defines.
The standard header <limits.h> contains various MAX, MIN constants
including numerial limits. [1]
I think it makes sense to move in-kernel MAX, MIN constants into
include/linux/limits.h.
We already have include/uapi/linux/limits.h to contain some user-space
constants. I changed its include guard to _UAPI_LINUX_LIMITS_H. This
change has no impact to the user-space because
scripts/headers_install.sh rips off the '_UAPI' prefix from the include
guards of exported headers.

Pull btrfs updates from David Sterba:
"This contains usual mix of new features, core changes and fixes; full
list below. I'm planning second pull request, with a few more fixes
that arrived recently but too close to merge window, will send it next
week.
New features:
- support zstd compression levels
- new ioctl to unregister a device from the module (ie. reverse of
device scan)
- scrub prints a message to log when it's about to start or finish
Core changes:
- qgroups can now skip part of a tree that does not get updated
during relocation, because this does not affect the quota
accounting, estimated speedup in run time is about 20%
- the compression workspace management had to be enhanced due to zstd
requirements
- various enospc fixes, when there's high fragmentation the
over-reservation can cause ENOSPC that might not happen after a
flush, in such cases try to wait if the situation improves
Fixes:
- various ioctls could overwrite previous return value if
copy_to_user fails, fix this so the original error is reported
- more reclaim vs GFP_KERNEL fixes
- other cleanups and refactoring
- fix a (valid) lockdep warning in a test when device replace is
destroying worker threads
- make qgroup async transaction commit more aggressive, this avoids
some 'quota limit reached' errors if there are not enough data to
trigger transaction in order to flush
- fix deadlock between snapshot deletion and quotas when backref
walking is called from context that already holds the same locks
- fsync fixes:
- fix fsync after succession of renames of different files
- fix fsync after succession of renames and unlink/rmdir"

Support for a new command that can be used eg. as a command
$ btrfs device scan --forget [dev]'
(the final name may change though)
to undo the effects of 'btrfs device scan [dev]'. For this purpose
this patch proposes to use ioctl #5 as it was empty and is next to the
SCAN ioctl.
The new ioctl BTRFS_IOC_FORGET_DEV works only on the control device
(/dev/btrfs-control) to unregister one or all devices, devices that are
not mounted.
The argument is struct btrfs_ioctl_vol_args, ::name specifies the device
path. To unregister all device, the path is an empty string.
Again, the devices are removed only if they aren't part of a mounte
filesystem.
This new ioctl provides:
- release of unwanted btrfs_fs_devices and btrfs_devices structures
from memory if the device is not going to be mounted
- ability to mount filesystem in degraded mode, when one devices is
corrupted like in split brain raid1
- running test cases which would require reloading the kernel module
but this is not possible eg. due to mounted filesystem or built-in

Add support for events with data type FSNOTIFY_EVENT_INODE
(e.g. create/attrib/move/delete) for inode and filesystem mark types.
The "inode" events do not carry enough information (i.e. path) to
report event->fd, so we do not allow setting a mask for those events
unless group supports reporting fid.
The "inode" events are not supported on a mount mark, because they do
not carry enough information (i.e. path) to be filtered by mount point.
The "dirent" events (create/move/delete) report the fid of the parent
directory where events took place without specifying the filename of the
child. In the future, fanotify may get support for reporting filename
information for those events.

If group requested FAN_REPORT_FID and event has file identifier,
copy that information to user reading the event after event metadata.
fid information is formatted as struct fanotify_event_info_fid
that includes a generic header struct fanotify_event_info_header,
so that other info types could be defined in the future using the
same header.
metadata->event_len includes the length of the fid information.
The fid information includes the filesystem's fsid (see statfs(2))
followed by an NFS file handle of the file that could be passed as
an argument to open_by_handle_at(2).

When user requests the flag FAN_REPORT_FID in fanotify_init(),
a unique file identifier of the event target object will be reported
with the event.
The file identifier includes the filesystem's fsid (i.e. from statfs(2))
and an NFS file handle of the file (i.e. from name_to_handle_at(2)).
The file identifier makes holding the path reference and passing a file
descriptor to user redundant, so those are disabled in a group with
FAN_REPORT_FID.
Encode fid and store it in event for a group with FAN_REPORT_FID.
Up to 12 bytes of file handle on 32bit arch (16 bytes on 64bit arch)
are stored inline in fanotify_event struct. Larger file handles are
stored in an external allocated buffer.
On failure to encode fid, we print a warning and queue the event
without the fid information.
[JK: Fold part of later patched into this one to use
exportfs_encode_inode_fh() right away]

The Tegra Combined UART (TCU) is a mailbox-based mechanism that allows
multiplexing multiple "virtual UARTs" into a single hardware serial
port. The TCU is the primary serial port on Tegra194 devices.
Add a TCU driver utilizing the mailbox framework, as the used mailboxes
are part of Tegra HSP blocks that are already controlled by the Tegra
HSP mailbox driver.

"Here is the big staging/iio driver pull request for 5.1-rc1.
Lots of good IIO driver updates and cleanups in here as always.
Combined with the removal of the xgifb driver, we have a net "loss" of
over 9000 lines in the pull request, always a nice thing.
As the outreachy application process is currently happening, there are
loads of tiny checkpatch cleanup fixes all over the staging tree,
which accounts for the majority of the fixups"

Jonathan writes:
First set of new device support, features and cleanup for IIO in the 5.1 cycle
A number of interesting new devices supported plus a good set of staging
cleanup including one graduation and one drop.
New device support
* ad56886
- Add support for AD5674R/AD5679R with some minor driver changes to support
more channels.
* ad7768
- New driver and dt bindings for this 24 bit ADC.
* max44009
- New driver and dt bindings for this ambient light sensor.
* mpu6050
- Support the ICM 20602 IMU. Minor tweaks due to slightly different
register map.
* NPCM adc
- New driver and dt bindings for this BMC ADC.
* Sensiron SGP30
- Modifiers for ethanol and H2.
- New driver and dt bindings.
- Follow patch added self cleaning support.
* Sensiron SPS30
- New channel type for mass concentration.
- New driver and bindings.
- Minor tidy up patch followed (drop fmt specifier as unused)
* st_pressure
- lps22hh support. ID plus information structures and dt bindings.
* ti-ads124s08
- Add binding doc and driver.
Staging graduations
* ad7606 driver and bindings.
Staging drops
* ad7152 CDC driver dropped. This part is near EoL and no one is known
to be using it. If anyone surfaces obviously we can bring the driver
back. If not, good to drop it to avoid wasting anyone's time cleaning
it up.
New features
* bme680
- DT support and bindings doc.
* isl29018
- Add regulator for VCC.
* mag3110
- Add regulators for supplies.
* meson-saradc
- Support the temperature sensors of more SoCs.
* mma8452
- Add regulators for power suplies and binding docs to reflect them.
* st-accel
- Support the undocumented but it seems fairly common _ONT ACPI method
to specify orientation of the sensor.
Cleanup, minor fixes and fixes for staging driver that have been broken a
long time
* ad5933
- Drop platform data alternative to specifying the reference voltage
using a regulator.
- Use the clock framework to contorl the reference clock.
- Add a DT binding doc to cover the defacto binding.
* ad7280a
- Split up some big functions to improve readability.
* ad7606
- Allow for timeout if interrupt never occurs.
- Use devm functions to simplify probe and remove.
- Use the find_closest macro to avoid need for precise values from
userspace.
- Add missing vendor prefixes for various DT properties. Note the
driver is in staging still and there are no known devicetrees.
- Add explict OF device ID table.
- Simplify the Kconfig choices
- Change to a threaded IRQ.
- SPDX and simple stype fixes.
* ad7816
- Drop unnecessary variable init.
* ad9523
- Check a return value that was ignored.
* ad9833
- Drop platform data. It was just setting most values to the hardware
defaults.
- Use the clock framework to provide the input clock.
* adt7316 (lots of staging cleanup)
- Fix some wrong register / bit definitions
- Invert the logic of the check for an ldac pin so it actually makes sense.
- Read the right register to get internal vref settings
- Allow adt751x chips to use the internal vref for all DAC channels rather
than a subset.
- Remove dac vref bypass control from parts that don't have one.
- Make the store DAC update mode function consistent with the show one.
- Fix some spellings and other minor tidy up.
- Avoid passing irq numbers around by putting all the irq logic in
one place.
- Fix an issue with the resolution of DAC control.
- Fix support of the high resolution DAC mode (for temp proportional output)
where supported.
- Fix DAC read and write calculations.
* st_lsm6dsx
- Drop an unused variable (set but not read)
* xilinx-xadc
- Check an unhandled return value.
