Cover letter [PATCH v3 00/10] KVM: arm64: FF-A proxy for pKVM

Hi all,

This is version three of the pKVM FF-A proxy series previously posted here:

v1: https://lore.kernel.org/r/[email protected]
v2: https://lore.kernel.org/r/[email protected]

Changes since v2 include:

* Rename 'spmd_' functions per suggestion from Oliver
* Add some more comments
* Rebase onto 6.4-rc3

Cheers,

Will
