Hi Jarkko,

Without the following two commits in your master branch, the last patch
in this series "[PATCH v4 6/6] integrity: PowerVM support for loading
third party code signing keys"   doesn't apply cleanly.

- commit 409b465f8a83 ("integrity: Enforce digitalSignature usage in
the ima and evm keyrings")
- commit e34a6c7dd192 ("KEYS: DigitalSignature link restriction")

If you're not planning on upstreaming this patch set, I'd appreciate
your creating a topic branch with these two commits.
