Subject: perf top using /proc/kcore

Hi Adrian,

	While testing 'perf top -U' to reply a message in another thread
I noticed that ksm symbols appeared as '[kernel]', and only when I tried
'perf top -U -v' to look at the DSO long name I noticed that it was...
/proc/kcore.

	Question is: since we have access to /proc/modules, can't we
parse that, as when we have access to vmlinux, and recreate the mmaps,
etc, and see:

	[module]  symbol

	Instead of grouping everything into a single [kernel] bucket?

- Arnaldo
