This patch series reworks some of the low-level aspects of KVM/ARM in
an effort to align it a bit more with what is offered by the ARMv8
architecture.
It covers the HYP ABI, the way we save/restore host and guest
contexts, the use of pt_regs for the register file, and the use of
H{I,D}FAR.
Tested on TC2. Patches against kvm-arm-master as of this morning.
