The first enables protected guests under pKVM when pvmfw is not being used (and therefore MMIO guard is not enabled). This is useful for pvmfw development and for testing a VMM outside of the Android Virtualisation Framework APIs. The second extends the ARM64 MAINTAINERS entry to cover the CCA and pKVM guest support, as neither of them are currently caught by an existing rule. Patches against v6.13-rc1.
