Since the machine reboots several times when running these tests, they must be run standalone and cannot be run with `runltp`. The first test verifies that the kernel command line is measured correctly when using kexec. The second test verifies that the IMA buffer is being passed through kexec correctly. Support for passing the IMA buffer through kexec has only been upstreamed on powerpc so far, with a patchset in the process of being upstreamed for support on arm64. Therefore, the only architectures that the tests allow you to run them on (via `uname -m`) are ppc, ppc64, ppcle, ppc64le, and aarch64. The tests have been verified on ARM64. Would appreciate if someone can execute the tests on a PowerPC machine and validate. Lachlan Sneff (2): IMA: Verify that the kernel cmdline is passed and measured correctly through the kexec barrier.
