rust: allow `clippy::unwrap_or_default` globally

2026-08-03T09:21:59+00:00

commit 4688cf884b3abcd12498e03b625d1916bf49a1e4 upstream.

Starting with rustc 1.88, the `clippy::unwrap_or_default` lint triggers
on `rust/kernel/soc.rs` if `CONFIG_CC_OPTIMIZE_FOR_SIZE=y`:

    warning: use of `unwrap_or` to construct default value
      --> ../rust/kernel/soc.rs:66:10
      |
   66 |         .unwrap_or(core::ptr::null())
      |          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: try: `unwrap_or_default()`

This is a clippy bug [1]: the lint decides whether an expression is
equivalent to `Default::default()` by inspecting the optimized MIR of
`<*const T as Default>::default` exported by `core`, so its outcome
depends on the optimization level `core` was built with. Moreover, its
suggestion ignores our MSRV of 1.85 (`Default` for `*const T` is only
stable since Rust 1.88), so we could not apply it anyway.

Disable the lint globally rather than working around this single
occurrence; it can be re-enabled conditionally using `rustc-min-version`
once clippy is fixed.

rust: Kbuild: set frame-pointer llvm module flag for CONFIG_FRAME_POINTER

2026-07-18T14:53:06+00:00

commit 191f49f1e38b1c10eb44b0f967c6175c884ef7db upstream.

Due to a rustc bug, the -Cforce-frame-pointers=y flag only emits the
frame-pointer annotation for functions, but not for the module. This
means that functions generated by the LLVM backend such as
'asan.module_ctor' do not receive the frame-pointer annotation.

This is likely to lead to broken backtraces and may also cause issues
with ftrace if these features are used with functions generated by the
LLVM backend.

Thus, use -Zllvm_module_flag to work around this rustc bug if using a
rustc without the fix.

[ The fix [1] has landed for Rust 1.98.0 (expected release on
  2026-08-20). - Miguel ]
