In repsonse to the prolonged discussion on issues with use of a
duplicated stack for jprobes on arm64 I have created the requested
change of removing the stack duplication code altogether. I don't know
how this affects systemtap. It would also be good to have a better idea
of how much systemtap makes use of jprobes.
The new additional patch, plus Catalin's accumulated patches since
kprobes64-v15, are now in my (recreated) kprobes64-v16 branch. If
someone has time to exercise this it I would be grateful.
Thanks,
