Hi Linus,

Two new features - measuring certificates and querying IMA for a file
hash - and three bug fixes are included in this pull request.

- Measuring certificates is like the rest of IMA, based on policy, but
requires loading a custom policy.  Certificates loaded onto a keyring,
for example during early boot, before a custom policy has been loaded,
are queued and only processed after loading the custom policy.

- IMA calculates and caches files hashes.  Other kernel subsystems,
and possibly kernel modules, are interested in accessing these cached
file hashes.  

The bug fixes prevents classifying a file short read (e.g. shutdown)
as an invalid file signature, adds a missing blank when displaying the
securityfs policy rules containing LSM labels, and, lastly, fixes the
handling of the IMA policy information for unknown LSM labels.
