    gcc: disable '-Warray-bounds' for gcc-13 too · 0da6e5fd
    Linus Torvalds authored
    We started disabling '-Warray-bounds' for gcc-12 originally on s390,
    because it resulted in some warnings that weren't realistically fixable
    (commit 8b202ee2: "s390: disable -Warray-bounds").
    
    That s390-specific issue was then found to be less common elsewhere, but
    generic (see f0be87c4: "gcc-12: disable '-Warray-bounds' universally
    for now"), and then later expanded the version check was expanded to
    gcc-11 (5a41237a: "gcc: disable -Warray-bounds for gcc-11 too").
    
    And it turns out that I was much too optimistic in thinking that it's
    all going to go away, and here we are with gcc-13 showing all the same
    issues.  So instead of expanding this one version at a time, let's just
    disable it for gcc-11+, and put an end limit to it only when we actually
    find a solution.
    
    Yes, I'm sure some of this is because the kernel just does odd things
    (like our "container_of()" use, but also knowingly playing games with
    things like linker tables and array layouts).
    
    And yes, some of the warnings are likely signs of real bugs, but when
    there are hundreds of false positives, that doesn't really help.
    
    Oh well.
