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 * tag 'objtool-urgent-2022-06-05' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/extable: Annotate ex_handler_msr_mce() as a dead end context_tracking: Always inline empty stubs x86: Always inline on_thread_stack() and current_top_of_stack() jump_label,noinstr: Avoid instrumentation for JUMP_LABEL=n builds x86/cpu: Elide KCSAN for cpu_has() and friends objtool: Mark __ubsan_handle_builtin_unreachable() as noreturn objtool: Add CONFIG_HAVE_UACCESS_VALIDATION
