Merge tag 'objtool-urgent-2022-06-05' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull objtool fixes from Thomas Gleixner:
- 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
