Please make it clear which patches are clean cherry-picks by using the
'-x' flag to 'git cherry-pick'. Furthermore, note which patches are
backports by clearly stating in the commit log message 'backported from
upstream commit XXX'. In this particular series, patches 1-3 are
cherry-picks, whereas 4 appears to need backporting. Backported patches
require a higher level of scrutiny, so knowing which patches to focus on
saves the reviewers a little time.

aActually i botched the description since they all come from upstream:

the patches with a subject line ending with 'CVE-2010-4251' are the same
one found in the CVE page (plus some syntax modification if needed)
while the 3 extraneous patches (3, 4 and 5) where picked by me, again
from upstream, and again modified to apply if needed.


Anyway, i'll regenerate the set: in absence of conflicts `cherry-pick
-x`, else "backported from".
