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)" # # Link: https://lore.kernel.org/lkml/20201013003203.4168817-26-samitolvanen@google.com/ # Link:
