Linus Torvalds 44688ffd11 A set of objtool fixes:
- Handle __ubsan_handle_builtin_unreachable() correctly and treat it as
     noreturn.
 
   - Allow architectures to select uaccess validation
 
   - Use the non-instrumented bit test for test_cpu_has() to prevent escape
     from non-instrumentable regions.
 
   - Use arch_ prefixed atomics for JUMP_LABEL=n builds to prevent escape
     from non-instrumentable regions.
 
   - Mark a few tiny inline as __always_inline to prevent GCC from bringing
     them out of line and instrumenting them.
 
   - Mark the empty stub context_tracking_enabled() as always inline as GCC
     brings them out of line and instruments the empty shell.
 
   - Annotate ex_handler_msr_mce() as dead end
