Hi all,

litmus7 [1][2], a tool that we develop and use to test the memory
model on hardware, is building on kvm-unit-tests to encapsulate full
system tests and control address translation. This series extends the
kvm-unit-tests arm MMU API and adds two memory attributes to MAIR_EL1
to make them available to the litmus tests.

v1: https://lore.kernel.org/kvm/20201102115311.103750-1-nikos.nikoleris@arm.com/T/

Changes in v2:
  - Add comment on break-before-make in get_mmu_pte()
  - Signed-off-by tag from all co-authors
  - Minor formatting changes

Thanks,

Nikos
