Linus Torvalds f59c074e76 Rust fixes for v7.3
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.
