As usual, the executive friendly graph is at

(No merge commits counted, next-20130701 was the linux-next based on v3.10)

Commits in v3.11-rc1 (relative to v3.10): 9494
Commits in next-20130701: 8929
Commits with the same SHA1: 7670
Commits with the same patch_id: 759 (1)
Commits with the same subject line: 55 (1)

(1) not counting those in the lines above.

So commits in -rc1 that were "in" next-20130701: 8484 89.4%
(essentially unchanged from 89.3% last time)
Commits in -rc1 that were not in next-20120722: 1010 10.6%

Pretty good, but it would be still nice to figure out where the last lot
came from. I have the "git log --oneline --no-walk" list if someone
wants them.

Some breakdown of that list:

Top ten first word of commit summary:

35 James Bottomley <JBottomley@xxxxxxxxxxxxx>
24 Dave Airlie <airlied@xxxxxxxxxx>
23 Thomas Gleixner <tglx@xxxxxxxxxxxxx>
23 Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

Quite a few of these could be bug fixes (especially DaveM's).

There are also 444 commits in next-20130701 that didn't make it into v3.11-rc1.

Top twelve first word of commit summary:

66 arm
37 mtd
31 drm/i915
11 rsxx
10 ocfs2
9 xen-blkback

11 Philip J Kelleher <pjk1939@xxxxxxxxxxxxxxxxxx>
10 Joern Engel <joern@xxxxxxxxx>
10 Daniel Vetter <daniel.vetter@xxxxxxxx>

Some of Andrew's patches are fixes for other patches in his tree (and
have been merged into those). Paul's patches are the __cpuinit removal
series that should be applied right after -rc1.

Top ten commiters:

184 Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
39 Artem Bityutskiy <artem.bityutskiy@xxxxxxxxxxxxxxx>
36 Shawn Guo <shawn.guo@xxxxxxxxxx>
31 Daniel Vetter <daniel.vetter@xxxxxxxx>
18 Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>
17 Michal Simek <michal.simek@xxxxxxxxxx>
17 Jens Axboe <axboe@xxxxxxxxx>
14 Simon Horman <horms+renesas@xxxxxxxxxxxx>
14 Joern Engel <joern@xxxxxxxxx>
11 Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

Well, that's embarrasing :-) Those commits by me are from the quilt
series (including Andrew's mmotm tree).

Some of the above will have been merged into other patches or replaced, I
guess.
