Subject: [PATCH v3 0/8] objtool: warning improvements

v3:
- dropped merged patches and rebased on tip/objtool/core

  objtool: Limit unreachable warnings to once per function
  objtool: Add verbose option for disassembling affected functions
  objtool: Include backtrace in verbose mode
  objtool: Detect missing __noreturn annotations
  objtool: Ignore exc_double_fault() __noreturn warnings
  objtool: Remove superfluous global_noreturns entries
  tools/lib/subcmd: Replace NORETURN usage with __noreturn
  objtool: Move noreturn function list to separate file
