[Will Deacon]

Hi all,

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

v1: https://lore.kernel.org/r/20221116170335.2341003-1-qperret@google.com
v2: https://lore.kernel.org/r/20230419122051.1341-1-will@kernel.org

Changes since v2 include:

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

Cheers,

Will
