    Linus:
    
    On the per-architecture side, I do think it would be better to *not* have
    internal architecture knowledge in a generic file, and as such a line like
    
            depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32
    
    really shouldn't exist in a file like kernel/Kconfig.instrumentation.
    
    It would be much better to do
    
            depends on ARCH_SUPPORTS_KPROBES
    
    in that generic file, and then architectures that do support it would just
    have a
    
            bool ARCH_SUPPORTS_KPROBES
                    default y
    
    in *their* architecture files. That would seem to be much more logical,
    and is readable both for arch maintainers *and* for people who have no
    clue - and don't care - about which architecture is supposed to support
    which interface...
    
    Changelog:
    
    Actually, I know I gave this as the magic incantation, but now that I see
    it, I realize that I should have told you to just use
    
            config KPROBES_SUPPORT
                    def_bool y
    
    instead, which is a bit denser.
    
    We seem to use both kinds of syntax for these things, but this is really
    what "def_bool" is there for...
    
    - Use HAVE_KPROBES
    - Use a select
    
    - Yet another update :
    Moving to HAVE_* now.
    
    - Update ARM for kprobes support.
