Subject: [PATCHSET 0/9] perf tools: Fixup for the --percentage change

Hello,

This patchset tries to fix bugs in percentage handling which is
recently changed.  The perf top with symbol filter could cause a
segfault (NULL pointer dereference) if the filter found no entry.

In this patchset, I moved accounting of various histogram stats to be
calculated at the time it actually shown to users.  Although I tested
it on my system for a while, it needs more testing since it'll affect
behaviors of many commands/usages.

It's available at 'perf/percentage-v10' branch on my tree:

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

Any comments, review and testing are welcomed.

Thanks,
Namhyung
