bf5ef3ce42 rtc: tegra: Replace deprecated SIMPLE_DEV_PM_OPS
Replace deprecated SIMPLE_DEV_PM_OPS with DEFINE_SIMPLE_DEV_PM_OPS macro
and use pm_sleep_ptr() to initialize pm_ops. This also allows us to drop
the checks for CONFIG_PM_SLEEP.

0a29345103 rtc: tegra: Add ACPI support
Add ACPI support for Tegra RTC, which is available on Tegra241 and
Tegra410. Both Tegra241 and Tegra410 use the same ACPI ID 'NVDA0280'.
When ACPI boot is used, the RTC clock is configured by UEFI before
the kernel boots. On device-tree boot, the probe must fail if clocks are
not provided in the device-tree.

b665c1b620 rtc: tegra: Use devm_clk_get_enabled() in probe
Simplify clock management by replacing devm_clk_get() and manual clock
enable/disable with devm_clk_get_enabled(). This also simplifies the
error handling logic. Also remove tegra_rtc_remove() as the clock will
automatically be disabled when the device is unbound from the bus.

73c4638a28 rtc: s35390a: use u8 instead of char for register buffer
The register buffer in s35390a_get_reg() was previously defined as
`char *buf`. This is not ideal since register data represents raw
binary values rather than textual data.

Switch the type to `u8 *buf` to better reflect its intended usage and
to avoid potential issues with sign extension when handling register
values on platforms where `char` is signed by default.

This change improves type safety and makes the code consistent with
other RTC drivers that operate on raw register data.

5630f7557d btrfs: do not skip logging new dentries when logging a new name
When we are logging a directory and the log context indicates that we
are logging a new name for some other file (that is or was inside that
directory), we skip logging the inodes for new dentries in the directory.

This is ok most of the time, but if after the rename or link operation
that triggered the logging of that directory, we have an explicit fsync
of that directory without the directory inode being evicted and reloaded,
we end up never logging the inodes for the new dentries that we found
during the new name logging, as the next directory fsync will only process
dentries that were added after the last time we logged the directory (we
are doing an incremental directory logging).

So make sure we always log new dentries for a directory even if we are
in a context of logging a new name.

We started skipping logging inodes for new dentries as of commit
c48792c6ee ("btrfs: do not log new dentries when logging that a new name
exists") and it was fine back then, because when logging a directory we
always iterated over all the directory entries (for leaves changed in the
current transaction) so a subsequent fsync would always log anything that
was previously skipped while logging a directory when logging a new name
(with btrfs_log_new_name()). But later support for incrementally logging
a directory was added in commit dc2872247e ("btrfs: keep track of the
last logged keys when logging a directory"), to avoid checking all dir
items every time we log a directory, so the check to skip dentry logging
added in the first commit should have been removed when the incremental
support for logging a directory was added.

A test case for fstests will follow soon.

266273eaf4 btrfs: don't log conflicting inode if it's a dir moved in the current transaction
We can't log a conflicting inode if it's a directory and it was moved
from one parent directory to another parent directory in the current
transaction, as this can result an attempt to have a directory with
two hard links during log replay, one for the old parent directory and
another for the new parent directory.

The following scenario triggers that issue:

1) We have directories "dir1" and "dir2" created in a past transaction.
   Directory "dir1" has inode A as its parent directory;

2) We move "dir1" to some other directory;

3) We create a file with the name "dir1" in directory inode A;

4) We fsync the new file. This results in logging the inode of the new file
   and the inode for the directory "dir1" that was previously moved in the
   current transaction. So the log tree has the INODE_REF item for the
   new location of "dir1";

5) We move the new file to some other directory. This results in updating
   the log tree to included the new INODE_REF for the new location of the
   file and removes the INODE_REF for the old location. This happens
   during the rename when we call btrfs_log_new_name();

6) We fsync the file, and that persists the log tree changes done in the
   previous step (btrfs_log_new_name() only updates the log tree in
   memory);

7) We have a power failure;

8) Next time the fs is mounted, log replay happens and when processing
   the inode for directory "dir1" we find a new INODE_REF and add that
   link, but we don't remove the old link of the inode since we have
   not logged the old parent directory of the directory inode "dir1".

As a result after log replay finishes when we trigger writeback of the
subvolume tree's extent buffers, the tree check will detect that we have
a directory a hard link count of 2 and we get a mount failure.

Fix this by never logging a conflicting inode that is a directory and was

transaction) and instead fallback to a transaction commit.

A test case for fstests will follow soon.

87213b0d84 ublk: allow non-blocking ctrl cmds in IO_URING_F_NONBLOCK issue
Handling most of the ublksrv_ctrl_cmd opcodes require locking a mutex,
so ublk_ctrl_uring_cmd() bails out with EAGAIN when called with the
IO_URING_F_NONBLOCK issue flag. However, several opcodes can be handled
without blocking:
- UBLK_CMD_GET_QUEUE_AFFINITY
- UBLK_CMD_GET_DEV_INFO
- UBLK_CMD_GET_DEV_INFO2
- UBLK_U_CMD_GET_FEATURES

Handle these opcodes synchronously instead of returning EAGAIN so
io_uring doesn't need to issue the command via the worker thread pool.

7329417fc9 drm/amd/display: shrink struct members
On a 32-bit ARM system, the audio_decoder struct ends up being too large
for dp_retrain_link_dp_test.

link_dp_cts.c:157:1: error: the frame size of 1328 bytes is larger than
1280 bytes [-Werror=frame-larger-than=]

This is mitigated by shrinking the members of the struct and avoids
having to deal with dynamic allocation.

feed_back_divider is assigned but otherwise unused. Remove both.

pixel_repetition looks like it should be a bool since it's only ever
assigned to 1. But there are checks for 2 and 4. Reduce to uint8_t.

Remove ss_percentage_divider. Unused.

Shrink refresh_rate as it gets assigned to at most a 3 digit integer
value.

cf841f6abc drm/amd/display: Refactor dml_core_mode_support to reduce stack frame
[WHAT]
When compiling Linux kernel with clang, the following warning / error
messages pops up:

drivers/gpu/drm/amd/amdgpu/../dal-dev/dc/dml2_0/display_mode_core.c:6853:12:

*mode_lib)

[HOW]
Refactoring CalculateVMRowAndSwath_params assignments to a new function
helps reduce the stack frame size in dml_core_mode_support.

The trap may be entered with dependency checking disabled.
Wait for dependency counters and save/restore scheduling mode.

v2:

Use ttmp1 instead of ttmp11. ttmp11 is not zero-initialized.
While the trap handler does zero this field before use, a user-mode
second-level trap handler could not rely on this being zero when
using an older kernel mode driver.

v3:

Use ttmp11 primarily but copy to ttmp1 before jumping to the
second level trap handler. ttmp1 is inspectable by a debugger.
Unexpected bits in the unused space may regress existing software.

edf47fb3d1 drm/amdgpu: introduce amdgpu_ttm_buffer_entity
No functional change for now, but this struct will have more
fields added in the next commit.

This change would introduce synchronisation issue, because
dependencies between successive jobs are not taken care of
properly. For instance, amdgpu_ttm_clear_buffer uses
amdgpu_ttm_map_buffer then amdgpu_ttm_fill_mem which should
use different entities (default_entity then move/clear entity).
To prevent failures for this commit, we limit ourselves to
2 entities: default_entity (which replaces high_pr usages) and
clear_entity (which replaces low_pr usages).

The next commits will deal with these dependencies correctly,
and then we'll be able to use move_entity.

assigned to 1. But there are checks for 2 and 4. Reduce to uint8_t.

Remove ss_percentage_divider. Unused.

Shrink refresh_rate as it gets assigned to at most a 3 digit integer
value.

7a5fb05b5b amdkfd: Bump ABI to indicate presence of Trap handler support for expert scheduling
commit 0f0c8a6983db ("drm/amdkfd: Trap handler support for expert
scheduling mode") introduced support for a trap handler when expert
scheduling mode. However userspace needs to know whether or not a trap
handler support is present.

Bump the KFD IOCTL API so that userspace can key off this to decide.

29a4dc4b5d drm/amd/display: Refactor dml_core_mode_support to reduce stack frame
[WHAT]
When compiling Linux kernel with clang, the following warning / error
messages pops up:

drivers/gpu/drm/amd/amdgpu/../dal-dev/dc/dml2_0/display_mode_core.c:6853:12:
error: stack frame size (2120) exceeds limit (2056) in
'dml_core_mode_support' [-Werror,-Wframe-larger-than]
 6853 | dml_bool_t dml_core_mode_support(struct display_mode_lib_st
*mode_lib)

[HOW]
Refactoring CalculateVMRowAndSwath_params assignments to a new function
helps reduce the stack frame size in dml_core_mode_support.

6b2e9b41b7 drm/amd/display: Defer transitions from minimal state to final state
[Why]
In non-seamless pipe transitions, it can take several frames to process
a single flip. One of the reasons is the 2-step transition implementation
where first the minimal transition state is applied, then the final state
is applied, all within the same flip. This delay is noticeable to the user
in some video playback scenarios, which makes for a bad user experience.

[How]
 - in applicable non-seamless cases, complete the flip with the minimal
   state applied, start a counter, and create all new contexts as minimal
 - if another pipe transition occurs while counting, reset the counter
 - when the counter finishes, promote the current flip to a full update
   and restore creation of optimized contexts
 - when creating minimal states from new context, apply stream updates

4238888794 drm/amdkfd: Trap handler support for expert scheduling mode
The trap may be entered with dependency checking disabled.
Wait for dependency counters and save/restore scheduling mode.

v2:

Use ttmp1 instead of ttmp11. ttmp11 is not zero-initialized.
While the trap handler does zero this field before use, a user-mode
second-level trap handler could not rely on this being zero when
using an older kernel mode driver.

v3:

Use ttmp11 primarily but copy to ttmp1 before jumping to the
second level trap handler. ttmp1 is inspectable by a debugger.
Unexpected bits in the unused space may regress existing software.
