Subject: [PATCH 0/4] KVM: arm64: pKVM host proxy FF-A fixes

Hello,


This series contains some small fixes for the host pKVM proxy code. I included
some of the patches that I already sent on the list as part of this series
to make it easier to keep track of them.

I verified the functionality with OPTEE as a TEE-OS.

Changelog:
 
* previously posted FFA_PARTITION_INFO_GET patch here:
https://lore.kernel.org/kvmarm/20240411133249.2134696-1-sebastianene@google.com/
 -> minor changes from the previous version, look for the current
    ffa_version in the host_buffer structure

* previously posted "Fix the identification range for the FF-A smcs" here:
https://lore.kernel.org/kvmarm/20240322124303.309423-1-sebastianene@google.com/

Thank you,
Sebastian
