[PATCH v3 0/6] KVM: arm64: Restrict host hypercalls when pKVM is enabled

Hi again folks,

This is version three of the patches I previously posted here:

  v1: https://lore.kernel.org/r/20210923112256.15767-1-will@kernel.org (local)
  v2: https://lore.kernel.org/r/20211005113721.29441-1-will@kernel.org (local)

Changes since v3 are:

  - Included proposed cleanup (using an enum) from Marc
  - Rebased onto -rc4

Cheers,

Will
