I have built a local version the uprobe/upstream_arm64_devel branch of https://github.com/pratyushanand/linux which includes those patches in a linux-4.4.0-rc3 kernel. The tests seemed to run fairly well and the results have been uploaded to dejazilla: https://web.elastic.org/~dejazilla/viewsummary.php?summary=%3D%27%3C56698DCC.3090207%40redhat.com%3E%27 === systemtap Summary === # of expected passes 6096 # of unexpected failures 111 # of unexpected successes 2 # of expected failures 333 # of unknown successes 2 # of known failures 89 # of untested testcases 97 # of unsupported tests 27 runtest completed at Thu Dec 10 05:54:32 2015 There are still some areas needing for for aarch64 such as stack backtrace support.
