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.
