Hi Will,
Can you please cross-check if following branch works perfectly with
kprobes_onthefly.exp and other systemtap tests.
https://github.com/pratyushanand/linux/tree/uprobe/upstream_arm64_devel_v1.1
Following patch in above branch should solve this issue.
https://github.com/pratyushanand/linux/commit/d0dcc6477f1279ab0bd99aefc30efdecb16c586e
However, I am not yet sure that above modification could be the best solution,
so discussing at arm kernel list.
