24eff17887 smb: client: let recv_done() avoid touching data_transfer after cleanup/move
Calling enqueue_reassembly() and wake_up_interruptible(&info->wait_reassembly_queue)
or put_receive_buffer() means the response/data_transfer pointer might
get re-used by another thread, which means these should be
the last operations before calling return.

bdd7afc6dc smb: client: let recv_done() cleanup before notifying the callers.
We should call put_receive_buffer() before waking up the callers.

For the internal error case of response->type being unexpected,
we now also call smbd_disconnect_rdma_connection() instead
of not waking up the callers at all.

Note that the SMBD_TRANSFER_DATA case still has problems,
which will be addressed in the next commit in order to make
it easier to review this one.

24b6afc36d smb: client: remove separate empty_packet_queue
There's no need to maintain two lists, we can just
have a single list of receive buffers, which are free to use.

It just added unneeded complexity and resulted in
ib_dma_unmap_single() not being called from recv_done()
for empty keepalive packets.

We should call ib_dma_unmap_single() and mempool_free() before calling
smbd_disconnect_rdma_connection().

And smbd_disconnect_rdma_connection() needs to be the last function to
call as all other state might already be gone after it returns.

The root cause is an initialization order problem. The lock is declared
as a global variable and intended to be initialized during module startup.
However, the procfs entry that uses this lock can be accessed by userspace
before the spin_lock_init() call has run. This creates a race window where
reading the proc file will attempt to use the lock before it is
initialized, leading to the crash.

For a global lock with a static lifetime, the correct and robust approach
is to use compile-time initialization.

ad69d62588 drm/xe/pf: Program LMTT directory pointer on all GTs within a tile
Previously, the LMTT directory pointer was only programmed for primary GT
within a tile. However, to ensure correct Local Memory access by VFs,
the LMTT configuration must be programmed on all GTs within the tile.
Lets program the LMTT directory pointer on every GT of the tile
to guarantee proper LMEM access across all GTs on VFs.

62eedd150f drm/amdgpu/discovery: fix fw based ip discovery
We only need the fw based discovery table for sysfs.  No
need to parse it.  Additionally parsing some of the board
specific tables may result in incorrect data on some boards.
just load the binary and don't parse it on those boards.

Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4441
