The IMA kselftest tests are for the coordination between the different
methods of verifying file signatures.  In particular, for the kexec
kernel image and kernel module signatures.

The initial IMA kselftest just verifies that in an environment
requiring signed kexec kernel images, the kexec_load syscall fails. 

This week I posted additional IMA kselftests[1][2], including one for
the kexec_file_load syscall.  I would really appreciate these
kselftests being reviewed/acked.
