Subject: [PATCHSET 0/5] perf annotate: Reduce memory footprint (v1)

Hello,

This is a part of my work to improve perf annotate.  At first, I'd
like reduce the size of struct annotation which will be allocated
together with struct symbol in some cases.  In fact, it doesn't use
most of them so it needs to slim down and lazy-allocate used part.

With this applied, size of the struct goes down from 96 to 48.

The code is available at perf/annotate-diet-v1 branch in

  git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Thanks,
Namhyung
