[PATCH v3 08/10] KVM: arm64: Handle FFA_MEM_LEND calls from the host

[DaeRo Lee]

Is it pKVM's policy to not manage Non-secure memory using FF-A, while the FF-A
specification supports memory management between Host/Guest within Non-secure
hypervisors?

Then, how does someone lend memory to a Guest from the Host/Guest via FF-A? Can
pKVM prevent this? Or should Host/Guest developers use it with caution?
