As discussed a lot in the past, the UBWC config must be coherent across
a number of IP blocks (currently display and GPU, but it also may/will
concern camera/video as the drivers evolve).
So far, we've been trying to keep the values reasonable in each of the
two drivers separately, but it really make sense to do so centrally,
especially given certain fields (e.g. HBB) may need to be gathered
dynamically.
To reduce room for error, move to fetching the config from a central
source, so that the data programmed into the hardware is consistent
across all multimedia blocks that request it.

Merge series from Sakari Ailus <sakari.ailus@linux.intel.com>:
Late last year I posted a set to switch to __pm_runtime_mark_last_busy()
and gradually get rid of explicit pm_runtime_mark_last_busy() calls in
drivers, embedding them in the appropriate pm_runtime_*autosuspend*()
calls. The overall feedback I got at the time was that this is an
unnecessary intermediate step, and removing the
pm_runtime_mark_last_busy() calls can be done after adding them to the
relevant Runtime PM autosuspend related functions.

If the callback is going to have to attempt to grab more locks, it is
useful to have an ww_acquire_ctx to avoid locking order problems.
Why not use the drm_exec helper instead? Mainly because (a) where
ww_acquire_init() is called is awkward, and (b) we don't really
need to retry after backoff, we can just move on to the next object.

For UNMAP/REMAP steps we could be needing to lock objects that are not
explicitly listed in the VM_BIND ioctl in order to tear-down unmapped
VAs. These helpers handle locking/preparing the needed objects.
Note that these functions do not strictly require the VM changes to be
applied before the next drm_gpuvm_sm_map_lock()/_unmap_lock() call. In
the case that VM changes from an earlier drm_gpuvm_sm_map()/_unmap()
call result in a differing sequence of steps when the VM changes are
actually applied, it will be the same set of GEM objects involved, so
the locking is still correct.
v2: Rename to drm_gpuvm_sm_*_exec_locked() [Danilo]
v3: Expand comments to show expected usage, and explain how the usage
is safe in the case of overlapping driver VM_BIND ops.

Consolidate the CPU-based SHA-256 code into a single module, following
what I did with SHA-512:
- Each arch now provides a header file lib/crypto/$(SRCARCH)/sha256.h,
replacing lib/crypto/$(SRCARCH)/sha256.c. The header defines
sha256_blocks() and optionally sha256_mod_init_arch(). It is included
by lib/crypto/sha256.c, and thus the code gets built into the single
libsha256 module, with proper inlining and dead code elimination.
- sha256_blocks_generic() is moved from lib/crypto/sha256-generic.c into
lib/crypto/sha256.c. It's now a static function marked with
__maybe_unused, so the compiler automatically eliminates it in any
cases where it's not used.
- Whether arch-optimized SHA-256 is buildable is now controlled
centrally by lib/crypto/Kconfig instead of by
lib/crypto/$(SRCARCH)/Kconfig. The conditions for enabling it remain
the same as before, and it remains enabled by default.
- Any additional arch-specific translation units for the optimized
SHA-256 code (such as assembly files) are now compiled by
lib/crypto/Makefile instead of lib/crypto/$(SRCARCH)/Makefile.

Since HMAC support is commonly needed and is fairly simple, include it
as a first-class citizen of the SHA-256 library.
The API supports both incremental and one-shot computation, and either
preparing the key ahead of time or just using a raw key. The
implementation is much more streamlined than crypto/hmac.c.
I've kept it consistent with the HMAC-SHA384 and HMAC-SHA512 code as
much as possible.
Testing of these functions will be via sha224_kunit and sha256_kunit,
added by a later commit.

Currently the SHA-224 and SHA-256 library functions can be mixed
arbitrarily, even in ways that are incorrect, for example using
sha224_init() and sha256_final(). This is because they operate on the
same structure, sha256_state.
Introduce stronger typing, as I did for SHA-384 and SHA-512.
Also as I did for SHA-384 and SHA-512, use the names *_ctx instead of
*_state. The *_ctx names have the following small benefits:
- They're shorter.
- They avoid an ambiguity with the compression function state.
- They're consistent with the well-known OpenSSL API.
- Users usually name the variable 'sctx' anyway, which suggests that
*_ctx would be the more natural name for the actual struct.
Therefore: update the SHA-224 and SHA-256 APIs, implementation, and
calling code accordingly.
In the new structs, also strongly-type the compression function state.

Add a one-shot SHA-224 computation function sha224(), for consistency
with sha256(), sha384(), and sha512() which all already exist.
Similarly, add sha224_update(). While for now it's identical to
sha256_update(), omitting it makes the API harder to use since users
have to "know" which functions are the same between SHA-224 and SHA-256.
Also, this is a prerequisite for using different context types for each.

Instead of having both sha256_blocks_arch() and sha256_blocks_simd(),
instead have just sha256_blocks_arch() which uses the most efficient
implementation that is available in the calling context.
This is simpler, as it reduces the API surface. It's also safer, since
sha256_blocks_arch() just works in all contexts, including contexts
where the FPU/SIMD/vector registers cannot be used. This doesn't mean
that SHA-256 computations *should* be done in such contexts, but rather
we should just do the right thing instead of corrupting a random task's
registers. Eliminating this footgun and simplifying the code is well
worth the very small performance cost of doing the check.
Note: in the case of arm and arm64, what used to be sha256_blocks_arch()
is renamed back to its original name of sha256_block_data_order().
sha256_blocks_arch() is now used for the higher-level dispatch function.
This renaming also required an update to lib/crypto/arm64/sha512.h,
since sha2-armv8.pl is shared by both SHA-256 and SHA-512.

First, move the declarations of sha224_init/update/final to be just
above the corresponding SHA-256 code, matching the order that I used for
SHA-384 and SHA-512. In sha2.h, the end result is that SHA-224,
SHA-256, SHA-384, and SHA-512 are all in the logical order.
Second, move sha224_block_init() and sha256_block_init() to be just
below crypto_sha256_state. In later changes, these functions as well as
struct crypto_sha256_state will no longer be used by the library
functions. They'll remain just for some legacy offload drivers. This
gets them into a logical place in the file for that.
No code changes other than reordering.

- Fix a regression caused by the anonymous inode rework. Making them
regular files causes various places in the kernel to tip over
starting with io_uring.
Revert to the former status quo and port our assertion to be based on
checking the inode so we don't lose the valuable VFS_*_ON_*()
assertions that have already helped discover weird behavior our
outright bugs.
- Fix the the upper bound calculation in fuse_fill_write_pages()
- Fix priority inversion issues in the eventpoll code

Merge series from Sakari Ailus <sakari.ailus@linux.intel.com>:
Late last year I posted a set to switch to __pm_runtime_mark_last_busy()
and gradually get rid of explicit pm_runtime_mark_last_busy() calls in
drivers, embedding them in the appropriate pm_runtime_*autosuspend*()
calls. The overall feedback I got at the time was that this is an
unnecessary intermediate step, and removing the
pm_runtime_mark_last_busy() calls can be done after adding them to the
relevant Runtime PM autosuspend related functions. The latter part has
been done and is present in Rafael's tree at the moment, also see

Now that we expose struct file_attr as our uapi struct rename all the
internal struct to struct file_kattr to clearly communicate that it is a
kernel internal struct. This is similar to struct mount_{k}attr and
others.

add support to add a directory for each client-id
with root at the dri level. Since the clients are
unique and not just related to one single drm device,
so it makes more sense to add all the client based
nodes with root as dri.
Also create a debugfs file which show the process
information for the client and create a symlink back
to the parent drm device from each client.

Requirement is to create per client-id based directories to
hold key debugging information and for that access to
root debugfs dentry is need which is not in one place
and that information cannot be stored in drm_device.
Move the debugfs functionality from drm_drv.c and drm_accel.c
to drm_debugfs.c This enables debugfs root node reference
directly drm_debugfs.c and hence enable to create per client-id
directory.
v8: Create drm_accel dentry only if it's config is enabled (Jeff, Hugo)
v8: Merge drm_drv and drm_accel debugfs patches (Koenig, Christian)
v10: Since we moved drm_debugfs_root, hence to handle drm bridge
debugfs add a new function which call drm_bridge_debugfs_params where
drm_debugfs_root is accessible.

Architecture's using perf events for hard lockup detection needs to
convert the watchdog_thresh to the event's period, some architecture
for example arm64 perform this conversion using the CPU's maximum
frequency which will be acquired by cpufreq. However by the time
the lockup detector's initialized the cpufreq driver may not be
initialized, thus launch a watchdog with inaccurate period. Provide
a function hardlockup_detector_perf_adjust_period() to allowing
adjust the event period. Then architecture can update with more
accurate period if cpufreq is initialized.

The function ata_log_supported() tests if a log page is supported by a
device using the General Purpose Log Directory log page, which lists the
size of all surported log pages. However, this log page is read from the
device using ata_read_log_page() every time ata_log_supported() is
called. That is not necessary.
Avoid reading the General Purpose Log Directory log page by caching its
content in the gp_log_dir buffer defined as part of struct ata_device.
The functions ata_read_log_directory() and ata_clear_log_directory() are
introduced to manage this buffer. ata_clear_log_directory() zero-fill
the gp_log_dir buffer every time ata_dev_configure() is called, that is,
when the device is first scanned and when it is being revalidated.
The function ata_log_supported() is modified to call
ata_read_log_directory() instead of ata_read_log_page().
The function ata_read_log_directory() calls ata_read_log_page() to read
the General Purpose Log Directory log page from the device only if the
first 16-bits word of the log is not equal to 0x0001, that is, it is not
equal to the ACS mandated value for the log version.
With this, the log page is read from the device only once for every
ata_dev_configure() call. For instance, with pr_debug enabled, a call
to ata_dev_configure() before this patch generates the following log
page accesses:
ata3.00: read log page - log 0x0, page 0x0
ata3.00: read log page - log 0x13, page 0x0
ata3.00: read log page - log 0x0, page 0x0
ata3.00: read log page - log 0x12, page 0x0
ata3.00: read log page - log 0x0, page 0x0
ata3.00: read log page - log 0x30, page 0x0
ata3.00: read log page - log 0x30, page 0x8
ata3.00: read log page - log 0x0, page 0x0
ata3.00: read log page - log 0x0, page 0x0
ata3.00: read log page - log 0x0, page 0x0
ata3.00: read log page - log 0x30, page 0x0
ata3.00: read log page - log 0x0, page 0x0
ata3.00: read log page - log 0x30, page 0x0
ata3.00: read log page - log 0x30, page 0x3
ata3.00: read log page - log 0x30, page 0x4
ata3.00: read log page - log 0x18, page 0x0
That is, the general purpose log directory page is read 7 times.
With this patch applied, the number of accesses to this log page is
reduced to one:
ata3.00: read log page - log 0x0, page 0x0
ata3.00: read log page - log 0x13, page 0x0
ata3.00: read log page - log 0x12, page 0x0
ata3.00: read log page - log 0x30, page 0x0
ata3.00: read log page - log 0x30, page 0x8
ata3.00: read log page - log 0x30, page 0x0
ata3.00: read log page - log 0x30, page 0x0
ata3.00: read log page - log 0x30, page 0x3
ata3.00: read log page - log 0x30, page 0x4

Introduce a kernel function which is the analogue of dump_stack()
printing some useful information and the stack trace. This is not
exposed to BPF programs yet, but can be made available in the future.
When we have a program counter for a BPF program in the stack trace,
also additionally output the filename and line number to make the trace
helpful. The rest of the trace can be passed into ./decode_stacktrace.sh
to obtain the line numbers for kernel symbols.
