    At that time I did most of all the CONFIG_HAVE_ARCH_TRACEHOOK work for ARM.
    The ARM kernel maintainers just weren't interested in paying attention, and
    I gave up on hounding them. Since then, only a subset of what I did before
    has actually been done and merged. (e.g. there is now some user_regset
    support, but less than what I implemented and posted originally--so for
    some ARM variants there is still register information only accessible via
    old ptrace calls but not in core dumps and no PTRACE_GETREGSET support.
    The really trivial stuff like using tracehook_report_* still hasn't gone
    in, though I posted that code back then too.)


    Thanks,
    Roland
