Subject: [PATCH 5.15 0/6] arm64: kexec_file: use more system keyrings to verify kernel image signature + dependencies

Hello,

this is backport of commit 0d519cadf751
("arm64: kexec_file: use more system keyrings to verify kernel image signature")
to table 5.15 tree including the preparatory patches.

Some patches needed minor adjustment for context.

Thanks

Michal
