I've added the prereq patches to
git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/security-testing-2.6#next

Please test it, and base your next version of the integrity patches on 
that branch.  Generally, if your patches depend on some other patches, you 
need to coordinate to ensure the prerequisite patches are either in the 
tree you're aiming for, or post them as part of the patchset.

Note that there are some interesting sparse warnings for the TPM code 
(not arising from the above):
