OK, *that* references the commit which is the problem, when went into
v3.11 (b9b32bf70f2fb710b07c94e13afbc729afe221da)

Unfortunately, *that commit* was cc:stable, so this needs to be
cc:stable as well, not just >= 3.11.

Looking back on those patches, there's a mass of cc:stable on them.  The
descriptions are either misleading, or these patches prevent theoretical
attacks which means they shouldn't have been cc:stable.

Grr...
Rusty.
