Subject: [PATCH v2 00/13] kbuild: second round of Clang LTO refactoring


Masahiro Yamada (13):
  kbuild: move objtool_args back to scripts/Makefile.build
  kbuild: rename __objtool_obj to objtool
  kbuild: store the objtool command in *.cmd files
  kbuild: factor out OBJECT_FILES_NON_STANDARD check into a macro
  kbuild: detect objtool update without using .SECONDEXPANSION
  kbuild: reuse $(cmd_objtool) for cmd_cc_lto_link_modules
  kbuild: do not create built-in.a.symversions or lib.a.symversions
  kbuild: build modules in the same way with/without Clang LTO
  kbuild: add cmd_and_savecmd macro
  kbuild: rebuild modules when objtool is updated for CONFIG_LTO_CLANG
  kbuild: always postpone CRC links for module versioning
  kbuild: merge cmd_modversions_c and cmd_modversions_S
  kbuild: merge cmd_ar_builtin and cmd_ar_module
