Hi Vladimir,
FYI, Here we found a 17% netperf regression by this patch. Here are some
changed stats between this commit 7e3115ef5149fc502e3a2e80719dba54a8e7409d
and it's parent(3029ede39373c368f402a76896600d85a4f7121b)
NOTE: both commit had been tested 10+ times.

increased vmap_area_lock contentions on "n_tty: Move buffers into n_tty_data"
by Fengguang Wu
Hi Peter,
FYI, we noticed much increased vmap_area_lock contentions since this
commit:
commit 20bafb3d23d108bc0a896eb8b7c1501f4f649b77
Author: Peter Hurley <peter(a)hurleysoftware.com>
Date: Sat Jun 15 10:21:19 2013 -0400
n_tty: Move buffers into n_tty_data
Reduce pointer reloading and improve locality-of-reference;
allocate read_buf and echo_buf within struct n_tty_data.

3-5% increased netperf throughput by "sched: Micro-optimize the smart wake-affine logic"
by Fengguang Wu
Hi Peter,
We are glad to report some measurable performance improvements by your
commit
commit 7d9ffa8961482232d964173cccba6e14d2d543b2
Author: Peter Zijlstra <peterz(a)infradead.org>
Date: Thu Jul 4 12:56:46 2013 +0800
sched: Micro-optimize the smart wake-affine logic
Smart wake-affine is using node-size as the factor currently, but the overhead
of the mask operation is high.
Thus, this patch introduce the 'sd_llc_size' percpu variable, which will record
the highest cache-share domain size, and make it to be the new factor, in order
to reduce the overhead and make it more reasonable.
