    kbuild: Demote 'sign-compare' warning to W=2 · 7599ea8b
    Lee Jones authored
    Ideally, a kernel compile with W=1 enabled should complete cleanly;
    however, when we run one currently we are presented with ~25k warnings.
    'sign-compare' accounts for ~22k of those ~25k.
    In this patch we're demoting 'sign-compare' warnings to W=2, with a view
    to fixing the remaining 3k W=1 warnings required for a clean build.
    Arnd adds:
      "As per our discussion, I'd add that this was inadvertedly introduced
       by Behan when he moved the clang specific warnings into an ifdef block
       and did not notice that -Wsign-compare was interpreted by both gcc
       and clang.
       Earlier, it was introduced in just the same way by Jan-Simon as part
       of 3d3d6b84 ("kbuild: LLVMLinux: Adapt warnings for compilation
       with clang")."
