Hi folks,

Here are a couple of minor tweaks to the CoCO guest support on arm64.

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.

Cheers,

Will
