The X-Git-Tag from the web page says it first appeared in mainline in
2.6.30-rc1:

From: Ingo Molnar <mingo@...e.hu>
Date: Thu, 14 Feb 2008 09:36:03 +0000 (+0100)
Subject: x86: unify stackprotector features
X-Git-Tag: v2.6.30-rc1~2^2~50^2~67^2~11
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=113c5413c

Looks like it went through three merges on the way there?
