Pull CXL (Compute Express Link) updates from Dave Jiang:
"The significant change of interest is the handling of soft reserved
memory conflict between CXL and HMEM. In essence CXL will be the first
to claim the soft reserved memory ranges that belongs to CXL and
attempt to enumerate them with best effort. If CXL is not able to
enumerate the ranges it will punt them to HMEM.
There are also MAINTAINERS email changes from Dan Williams and
Jonathan Cameron"

When platform_device_register() fails in do_floppy_init(), the embedded
struct device in floppy_device[drive] has already been initialized by
device_initialize(), but the failure path jumps to out_remove_drives
without dropping the device reference for the current drive.
Previously registered floppy devices are cleaned up in out_remove_drives,
but the device for the drive that fails registration is not, leading to
a reference leak.
The issue was identified by a static analysis tool I developed and
confirmed by manual review. Fix this by calling put_device() for the
current floppy device before jumping to the common cleanup path.

Bio pages may originate from slab caches that lack a usercopy region
(e.g. jbd2 frozen metadata buffers allocated via jbd2_alloc()).
When CONFIG_HARDENED_USERCOPY is enabled, copy_to_iter() calls
check_copy_size() which rejects these slab pages, triggering a
kernel BUG in usercopy_abort().
This is a false positive: the data is ordinary block I/O content —
the same data the loop driver writes to its backing file via
vfs_iter_write(). The bvec length is always trusted, so the size
check in check_copy_size() is not needed either.
Switch to _copy_to_iter()/_copy_from_iter() which skip the
check_copy_size() wrapper while the underlying copy_to_user()
remains unchanged.

The main changes happened in the SunXi driver in order to

aside with the usual load of misc changes.

SPI NOR changes for 7.1
There is only a collection of bugfixes this time around, with no notable
changes to the core. Some of the more noteworthy bugfixes listed below.
- Enable die erase on MT35XU02GCBA. We knew this flash needed this fixup
since 7f77c561e227 ("mtd: spi-nor: micron-st: add TODO for fixing
mt35xu02gcba") but did not add it due to lack of hardware to test on.
- Fix locking on some Winbond w25q series flashes.
- Fix Auto Address Increment (AAI) writes on SST that flashes that start
on odd address. The write enable latch needs to be set again after the
single byte program.

radeon_ring_restore() takes ownership of the data buffer allocated by
radeon_ring_backup(). The caller (radeon_gpu_reset()) only frees it in
the non-restore branch; in the restore branch it relies on
radeon_ring_restore() to free it.
If radeon_ring_lock() fails, the function returned early without calling
kvfree(data), leaking the ring backup buffer on every GPU reset that
fails at the lock stage. During repeated GPU resets this causes
cumulative kernel memory exhaustion.
Free data before returning the error.

radeon_align_pitch() has the same kind of overflow issue as the old
amdgpu helper: both the alignment round-up add and the final
'aligned * cpp' calculation can overflow signed int.
If that wraps, radeon_mode_dumb_create() can end up returning an
invalid pitch or creating a zero-sized dumb buffer.
Fix this by using check_add_overflow() for the alignment round-up and
check_mul_overflow() for the final pitch calculation, returning 0 on
overflow. Also reject zero pitch and size in
radeon_mode_dumb_create().
Found via AST-based call-graph analysis using sqry.

[Why]
Multiple display source files contain implicit narrowing
conversions when assigning wider integer types (int, uint32_t)
to narrower fields (uint8_t, uint16_t) at hardware register,
protocol, and storage boundaries. These conversions are
intentional but undocumented, and accompanying runtime assertions
add noise without providing compile-time safety.
[How]
Add explicit casts at all intentional narrowing boundaries across
display source files. Use narrower loop variable types where loop
bounds guarantee safe range. Remove runtime assertions paired
with narrowing casts, inline single-use intermediate variables,
and revert block scopes and braces introduced solely to contain
those assertions.

From MES version 0x74 and above, pipe 1(kiq) support use the
shared command buffer to distribute the tasks among the xccs
within the same partition. It's more efficient for tlb invalidation
been done individually on the each XCC at the same time compare
to let master xcc loop all xccs.
This requires the coop_mode been set before kiq set_hw_resource.

Same as compute and sdma, gfx_hqd_mask has been initialized properly in
amdgpu_mes_init. set_hw_res should use those initialization accordingly.
Hardcoding it causes the mismatch between driver and MES.
