Where do I find description what has been changed in gentoo-sources with respect to vanilla-sources?

You can browse http://dev.gentoo.org/~mpagano/genpatches/

You can also view the README of some genpatches-X.Y-Z.base.tar.xz
You'll discover the patchset numbering scheme and can deduce that those starting with a number >=1500 are not included in vanilla.
Of course, all patches included in genpatches-X.Y-Z.extras.tar.xz are not included in vanilla as well, but the content of the extras patchset is nowadays limited to the fbcondecor patch.

But... Nolite sanctum dare canibus... :wink:

OK, thanks.
So in fact there is not much difference, especially if someone doesn't use BFQ on Thinkpad with bootsplash. :)

Anything else distinguish these two kernels, e.g. default config, any scripts, documentation?

You are grosso-modo correct.

There is one *big* difference in principle which rarely translates into a *big* difference between vanilla and gentoo kernels :

As a matter of fact, the vanilla ebuilds say : K_SECURITY_UNSUPPORTED="1"
This can mean that as soon as a branch is declared EOL upstream, no security patch will be backported on vanilla kernels of that branch.
But if the gentoo-sources still get that branch in portage, the gentoo devs should backport it.

As an example, this happened with the 3.7
genpatches-3.7-15.base.tar.xz wrote:
1600_CVE-2013-2094_perf-swevent...

So the longer a gentoo-sources is living after the corresponding branch is declared EOL by upstream, the more vanilla-sources/gentoo-sources differ on that branch.

Not really.
Well, about a default config, not... yet.
I've heard that ago had plans and work aiming at that sort of thing.
