Thank you. Unfortunately no time to review this anymore this week but I
sanity checked that this applies cleanly now, so should be easy to get on
testing this series next week:

$ git-pw series apply 414691
Applying: certs/blacklist: fix kernel doc interface issue
Applying: certs: Fix blacklisted hexadecimal hash string check
Applying: PKCS#7: Fix missing include
Applying: certs: Fix blacklist flag type confusion
Applying: certs: Replace K{U,G}IDT_INIT() with GLOBAL_ROOT_{U,G}ID
Applying: certs: Make blacklist_vet_description() more strict
Applying: certs: Factor out the blacklist hash creation
