No. In fact annotation works now with kcore. Linus' problem was
with vmlinux.
Kcore won't be used with kaslr in the case:
1. record data with 'perf record'
2. reboot
3. use annotation on the previously recorded data
As I noted in the commit message, you can still use kcore if you made a copy
(with perf buildid-cache) at the time the data was recorded.
Not that I care much about this particular case; but you could also save
the offset at record time and do double offset correction assuming its
still the same kernel you booted into but at a different location.
