This refers to the work I did, which is only user_regset, tracehook, and
asm/syscall.h cleanups for ARM. None of that went in, though not for any
particular reason. Since then someone did something about asm/syscall.h
IIRC, but nobody has ever paid enough attention to merge the user_regset
and tracehook work I did. That stuff is internal kernel cleanups that
don't by itself give you any exciting new features (only some core-dump
support for the arcane register flavors that lacked them).
I have never done any work related to ARM support for instruction-copying
breakpoint insertion, which is the crux of kprobes and uprobes. I'm not
aware of what others may have done in those areas.
Thanks,
Roland
