Subject: [RFC/PATCH 0/6] perf tools: Additional works for memory access sampling

Hi,

During playing with the Stephane's memory access sampling series [1],
I needed to have these patches to make perf mem work properly.

It still gets a segfult when analyzing system wide sample data, and
needs more work on dealing with kernel's percpu symbols and rodata
symbols in user app, it worked well for my toy application at least
sometimes. ;-) I'll continue to chasing it down but before doing it
I'd like to share what I have now.

Thanks,
Namhyung
