And what's next now? Maxim mentioned in this thread you should sort of formally approve(?) a global feature, have you had a look at it yet?
I should emphasize that this code can substitute the -fentry for arm64 for
the purpose of kernel live patching that was discussed in the beginning,
as well as for some other architectures, plus the yet-to-be-discovered use
cases as a general instrumentation. In other words, it could save some work
in the future :-)
