The Key Service support is split between 4 main patches (10-13), but
the dependencies go further back in the patchset.

If the bisect need outweighs any benefit from reviewing in pieces,
then these patches can be squashed to a single patch:

keys/mktme: Add the MKTME Key Service type for memory encryption
keys/mktme: Program memory encryption keys on a system wide basis
keys/mktme: Save MKTME data if kernel cmdline parameter allows
keys/mktme: Support CPU Hotplug for MKTME keys

Am I interpreting your point correctly?
Thanks,
