2b04d04de9 drm/amdkfd: Fix error handling for missing PASID in 'kfd_process_device_init_vm'
In the kfd_process_device_init_vm function, a valid error code is now
returned when the associated Process Address Space ID (PASID) is not
present.

If the address space virtual memory (avm) does not have an associated
PASID, the function sets the ret variable to -EINVAL before proceeding
to the error handling section. This ensures that the calling function,
such as kfd_ioctl_acquire_vm, can appropriately handle the error,
thereby preventing any issues during virtual memory initialization.

Fixes the below:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_process.c:1694 kfd_process_device_init_vm()
warn: missing error code 'ret'

drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_process.c
    1647 int kfd_process_device_init_vm(struct kfd_process_device *pdd,
    1648                                struct file *drm_file)
    1649 {
    ...
    1690
    1691         if (unlikely(!avm->pasid)) {
    1692                 dev_warn(pdd->dev->adev->dev, "WARN: vm %p has no pasid associated",
    1693                                  avm);
--> 1694                 goto err_get_pasid;

ret = -EINVAL?

    1695         }

dc0297f319 drm/amdgpu: Replace Mutex with Spinlock for RLCG register access to avoid Priority Inversion in SRIOV
RLCG Register Access is a way for virtual functions to safely access GPU
registers in a virtualized environment., including TLB flushes and
register reads. When multiple threads or VFs try to access the same
registers simultaneously, it can lead to race conditions. By using the
RLCG interface, the driver can serialize access to the registers. This
means that only one thread can access the registers at a time,
preventing conflicts and ensuring that operations are performed
correctly. Additionally, when a low-priority task holds a mutex that a
high-priority task needs, ie., If a thread holding a spinlock tries to
acquire a mutex, it can lead to priority inversion. register access in
amdgpu_virt_rlcg_reg_rw especially in a fast code path is critical.

The call stack shows that the function amdgpu_virt_rlcg_reg_rw is being
called, which attempts to acquire the mutex. This function is invoked
from amdgpu_sriov_wreg, which in turn is called from
gmc_v11_0_flush_gpu_tlb.

The [ BUG: Invalid wait context ] indicates that a thread is trying to
acquire a mutex while it is in a context that does not allow it to sleep
(like holding a spinlock).

Fixes the below:

72d7a7fa1f drm/amd/display: Guard against setting dispclk low when active
[Why]
We should never apply a minimum dispclk value while in prepare_bandwidth
or while displays are active. This is always an optimization for when
all displays are disabled.

[How]
Defer dispclk optimization until safe_to_lower = true and display_count
reaches 0.

Since 0 has a special value in this logic (ie. no dispclk required)
we also need adjust the logic that clamps it for the actual request
to PMFW.

drm/i915/dp: Fix error handling during 128b/132b link training
At the end of a 128b/132b link training sequence, the HW expects the
transcoder training pattern to be set to TPS2 and from that to normal
mode (disabling the training pattern). Transitioning from TPS1 directly
to normal mode leaves the transcoder in a stuck state, resulting in
page-flip timeouts later in the modeset sequence.

Atm, in case of a failure during link training, the transcoder may be
still set to output the TPS1 pattern. Later the transcoder is then set
from TPS1 directly to normal mode in intel_dp_stop_link_train(), leading
to modeset failures later as described above. Fix this by setting the
training patter to TPS2, if the link training failed at any point.

The clue in the specification about the above HW behavior is the
explicit mention that TPS2 must be set after the link training sequence
(and there isn't a similar requirement specified for the 8b/10b link
training), see the Bspec links below.

v2: Add bspec aspect/link to the commit log. (Jani)

drm/i915/dp: Fix disabling the transcoder function in 128b/132b mode
During disabling the transcoder in DP 128b/132b mode (both in case of an
MST master transcoder and in case of SST) the transcoder function must
be first disabled without changing any other field in the register (in
particular leaving the DDI port and mode select fields unchanged) and
clearing the DDI port and mode select fields separately, later during
the disabling sequences. Fix the sequence accordingly.

check_directory_size() was also inefficient, since keys in multiple

b587fd1286 cifs: Treat unhandled directory name surrogate reparse points as mount directory nodes
If the reparse point was not handled (indicated by the -EOPNOTSUPP from
ops->parse_reparse_point() call) but reparse tag is of type name surrogate
directory type, then treat is as a new mount point.

Name surrogate reparse point represents another named entity in the system.

From SMB client point of view, this another entity is resolved on the SMB
server, and server serves its content automatically. Therefore from Linux
client point of view, this name surrogate reparse point of directory type
crosses mount point.

9df23801c8 smb311: failure to open files of length 1040 when mounting with SMB3.1.1 POSIX extensions
If a file size has bits 0x410 = ATTR_DIRECTORY | ATTR_REPARSE set
then during queryinfo (stat) the file is regarded as a directory
and subsequent opens can fail. A simple test example is trying
to open any file 1040 bytes long when mounting with "posix"
(SMB3.1.1 POSIX/Linux Extensions).

The cause of this bug is that Attributes field in smb2_file_all_info
struct occupies the same place that EndOfFile field in
smb311_posix_qinfo, and sometimes the latter struct is incorrectly
processed as if it was the first one.

7330195e60 smb: client, common: Avoid multiple -Wflex-array-member-not-at-end warnings
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.

So, in order to avoid ending up with flexible-array members in the
middle of other structs, we use the `__struct_group()` helper to
separate the flexible arrays from the rest of the members in the
flexible structures. We then use the newly created tagged `struct
smb2_file_link_info_hdr` and `struct smb2_file_rename_info_hdr`
to replace the type of the objects causing trouble: `rename_info`
and `link_info` in `struct smb2_compound_vars`.

We also want to ensure that when new members need to be added to the
flexible structures, they are always included within the newly created
tagged structs. For this, we use `static_assert()`. This ensures that the
memory layout for both the flexible structure and the new tagged struct
is the same after any changes.

So, with these changes, fix 86 of the following warnings:

fs/smb/client/cifsglob.h:2335:36: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
fs/smb/client/cifsglob.h:2334:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
