Linus Torvalds 2aff7c706c Objtool changes for v6.4:
- Mark arch_cpu_idle_dead() __noreturn, make all architectures & drivers that did
    this inconsistently follow this new, common convention, and fix all the fallout
    that objtool can now detect statically.
 
  - Fix/improve the ORC unwinder becoming unreliable due to UNWIND_HINT_EMPTY ambiguity,
    split it into UNWIND_HINT_END_OF_STACK and UNWIND_HINT_UNDEFINED to resolve it.
 
  - Fix noinstr violations in the KCSAN code and the lkdtm/stackleak code.
 
  - Generate ORC data for __pfx code
 
  - Add more __noreturn annotations to various kernel startup/shutdown/panic functions.
 
  - Misc improvements & fixes.
