This series adds support for using KVM on ARM Cortex-A7 CPUs. As the Cortex-A7
is architecturally identical to the A15 there is not a huge amount of code
required, however there are a number of fixups necessary to core KVM code that
testing on A7 has revealed.
I'm open to comments about other ways to share the functionality between A7/A15
while still maintaining the architectural/implementation defined split that
existed between coproc.c and coproc_a15.c - The approach in this series avoids
adding '3 levels' of abstraction and feels like a good compromise that doesn't
require duplication of a lot of the A15 code for A7 but still permits
implementation differences to be fully expressed in coproc_X files.
This patch series has been developed/tested on TC2 with the A15 cluster held in
reset.
