# commit 44688ffd111af31984237f0cba05f2e201eac530
# Merge: b2c9a83d262a 2028a255f4df
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     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
#
