1da91ea87a introduce fd_file(), convert all accessors to it. 
For any changes of struct fd representation we need to
turn existing accesses to fields into calls of wrappers.
Accesses to struct fd::flags are very few (3 in linux/file.h,
1 in net/socket.c, 3 in fs/overlayfs/file.c and 3 more in
explicit initializers).
	Those can be dealt with in the commit converting to
new layout; accesses to struct fd::file are too many for that.
	This commit converts (almost) all of f.file to
fd_file(f).  It's not entirely mechanical ('file' is used as
a member name more than just in struct fd) and it does not
even attempt to distinguish the uses in pointer context from
those in boolean context; the latter will be eventually turned
into a separate helper (fd_empty()).

	NOTE: mass conversion to fd_empty(), tempting as it
might be, is a bad idea; better do that piecewise in commit
that convert from fdget...() to CLASS(...).

This happens because the UAPI provides only seven configuration
registers and we are reading the eighth position of this u32 array.

Therefore, fix the out-of-bounds read in `v3d_csd_job_run()` by
accessing only seven positions on the '__u32 [7]' array. The eighth
register exists indeed on V3D 7.1, but it isn't currently used. That
being so, let's guarantee that it remains unused and add a note that it
could be set in a future patch.

3998260373 drm/mediatek: Use cmdq_pkt_eoc() instead of cmdq_pkt_finalize() 
For some client driver, it want to reduce latency between excuting
previous packet command and next packet command, so append jump
command to the end of previous packet and the jump destination
address is the start address of next packet command buffer. Before
next packet exist, the previous packet has no information of where
to jump to, so append nop command first. When next packet exist,
change nop command to jump command. For mediatek drm driver, it
never has next packet, so appending nop command is redundant.
Because cmdq_pkt_finalize() would append nop command, so change
calling cmdq_pkt_finalize() to cmdq_pkt_eoc() to prevent append
redundant nop command.

549dd786b6 drm/xe: Move VM dma-resv lock from xe_exec_queue_create to __xe_exec_queue_init 
The critical section which requires the VM dma-resv is the call
xe_lrc_create in __xe_exec_queue_init. Move this lock to
__xe_exec_queue_init holding it just around xe_lrc_create. Not only is
good practice, this also fixes a locking double of the VM dma-resv in
the error paths of __xe_exec_queue_init as xe_lrc_put tries to acquire
this too resulting in a deadlock.

a request on the regions, however, which would make the driver a bit more

Replace pcim_iomap() with pcim_iomap_region().
