![]() - 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.
