Subject: [PATCHSET 0/9] perf tools: Assorted fixes and changes on perf top/report

Hi,

This patchset is a collection of 3 changes on perf top and report
tools.  I wanted to make them independent, but failed due to laziness. :)

Patch 1 is a fix for -E option handling in perf top.  IIUC it only
shows a given number of entries.  Patch 2 is a simple fix.

Patch 3-5 remove a set of _threaded() functions and also remove
unnecessary locking on perf report path.  It leads to a small
performance gain.

Patch 6-9 implement a long-requested --percent-limit option.  I
preserve the default value to 0 but an user can set it to a different
value using the .perfconfig file.

You can get it from 'perf/top-v1' branch on my tree at:

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

Any comments are welcome, thanks.
Namhyung
