#     
#     Pull more clang LTO updates from Kees Cook:
#      "Clang LTO x86 enablement.
#     
#       Full disclosure: while this has _not_ been in linux-next (since it
#       initially looked like the objtool dependencies weren't going to make
#       v5.12), it has been under daily build and runtime testing by Sami for
#       quite some time. These x86 portions have been discussed on lkml, with
#       Peter, Josh, and others helping nail things down.
#     
#       The bulk of the changes are to get objtool working happily. The rest
#       of the x86 enablement is very small.
#     
#       Summary:
#     
#        - Generate __mcount_loc in objtool (Peter Zijlstra)
#     
#        - Support running objtool against vmlinux.o (Sami Tolvanen)
#     
#        - Clang LTO enablement for x86 (Sami Tolvanen)"
