I agree they should be backported, but they don't apply cleanly before
linux-5.6.  The changes aren't that major.  Some patch hunks apply
cleanly, but won't compile, while others patch hunks need to be
dropped based on when the feature was upstreamed.  For these reasons,
I'm not Cc'ing stable.

Feature upstreamed:
- LSM policy update: linux 5.3
- key command line: linux 5.3
- blacklist: linux 5.5
- keyrings: linux 5.6

For Linux 5.3:
- Dependency on backporting commit 483ec26eed42 ("ima: ima/lsm policy
rule loading logic bug fixes") to apply " ima: Free the entire rule if
it fails to parse".
