[PATCH 0/4] objtool: Improve code generation for annotation macros

[Josh Poimboeuf <jpoimboe@kernel.org>]

For tip/objtool/core.

As much as possible, undo the code generation damage introduced by
ANNOTATE_DATA_SPECIAL:

  - Remove its usage in favor of SHF_MERGE + sh_entsize, where possible

  - Print the annotation on a single line:

      912: .pushsection ".discard.annotate_data", "M", @progbits, 8; .long 912b - .; .long 1; .popsection

  - Remove the trailing newline/tab; let the invoking code decide on the
    appropriate separator for the given context

Josh Poimboeuf (4):
  x86/alternative: Remove ANNOTATE_DATA_SPECIAL usage
  x86/asm: Remove ANNOTATE_DATA_SPECIAL usage
  objtool: Consolidate annotation macros
  objtool: Remove newlines and tabs from annotation macros
