The komeda crtc implementation provides a custom reset hook. However,
this hook only allocates the state, initializes it with
__drm_atomic_helper_crtc_reset(), and frees the previous state. It
does not perform any hardware reset.
Since this is exactly what the atomic_create_state hook is meant to
do, minus the old state cleanup which the caller handles, convert the
implementation to use atomic_create_state with
__drm_atomic_helper_crtc_state_init() instead.

(i.e. the monitor's EDID is larger than the 256 bytes ASPEED DP can
hold), report it as an all-zero block instead of a read failure.
Also remove the manual checksum/extension-count patch of block 0's
last four bytes. That code was already dead, so the condition can never

caused a regression (Peter Zijlstra)

Pull locking fix from Ingo Molnar:
- Revert a commit to spinlock cleanup guards that got caught up
in the subtle limitations & fragility of guards (again...) and
caused a regression (Peter Zijlstra)
* tag 'locking-urgent-2026-08-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
locking: Revert switching guards to _irq_{disable,enable}()
Toolchain and infrastructure:
- Fix KCFI failures, such as in Rust doctests, by disabling function
merging when CFI is enabled. Gary reported the LLVM bug to upstream
and it is now fixed in their mainline.
- Fix 'objtool' fallthrough warnings under the experimental
'CONFIG_RUST_INLINE_HELPERS' by passing (for the combined Rust and
helpers code) the LLVM options needed to preserve the unreachable
traps that 'rustc' normally emits.
In addition, fix 'objtool' errors when LTO is enabled on top, by
also filtering out the LTO flags (for the combined Rust and helpers
code) so that the traps are kept in place.
- Fix 'objtool' warnings by adding one more 'noreturn' function.
- Fix 'make rusttest' target when the 'rustc-dev' component is
installed and Rust >= 1.82.0, <= 1.87.0 is used.
'kernel' crate:
- 'num' module: fix soundness issue in the 'Bounded' conversion from
'bool' by restricting the conversions to unsigned 'Bounded'.
- 'jump_label' module: fix future 'make rusttest' target failures when
'ARCH=' is set to an arch different than the host's.
- 'list' module: fix incorrect 'pop_back()' comment.
