(Get the code!)
Yeah, what I meant was that the live-patch kernel-parts should work on all architectures, but probably not the kpatch-build tooling - in deed.
I read a bit about it at some common information sources, like https:/
But I mainly opened this because of an ongoing conversation between Dustin and Eberhard Pasch (from the Linux on s390x / z performance team at IBM) - Leann and Martin Schwidefsky (sub-system maintainer for s390x) got involved into this thread, too.
"
For the kernel patching - I [Eberhard] talked to Martin Schwidefsky (the s390x
maintainer) before he left for the kernel summit. Livepatch should
work upstream. And it's working in one of the competitive distros [probably SUSE].
If something is broken upstream, we'd like to know as it needs fixing then.
When we implemented it, we had quite some performance troubles with
the additional space we needed at the beginning of every function
and the code around that. But that should been fixed as well.

According to your statement about the incompatibility with the stack backtrace code and potentially some other things, it looks like IBM has to have a deeper look at it ...
Can we start to work with IBM to get the remaining issues solved based on this ticket ?
I may ask IBM to reverse proxy this ticket back to their internal bugzilla system ...
