Hi Linus,

Included in this pull request are bug fixes, code clean up, and new
features.  Listed below are the main changes.

- IMA policy rules can be defined in terms of LSM labels, making the
IMA policy dependent on LSM policy label changes, in particular LSM
label deletions.  The new environment, in which IMA-appraisal is being
used, frequently updates the LSM policy and permits LSM label
deletions.

- Prevent an mmap'ed shared file opened for write from also being
mmap'ed execute.  In the long term, making this and other similar
changes at the VFS layer would be preferable.

- The IMA per policy rule template format support is needed for a
couple of new/proposed features (eg. kexec boot command line
measurement, appended signatures, and VFS provided file hashes).

- Other than the "boot-aggregate" record in the IMA measuremeent list,
all other measurements are of file data.  Measuring and storing the
kexec boot command line in the IMA measurement list is the first
buffer based measurement included in the measurement list.

(Stephen is carrying a patch to address a merge conflict with David's
"Keys: Set 4 - Key ACLs for 5.3").

thanks,

Mimi
