Subject: [PATCH 12/26] KVM: arm64: Move arm_{psci,hypercalls}.h to an internal
KVM path
From: Anish Ghulati <aghulati@...gle.com>
Move arm_hypercalls.h and arm_psci.h into arch/arm64/kvm now that KVM
no longer supports 32-bit ARM, i.e. now that there's no reason to make
the hypercall and PSCI APIs "public".
Signed-off-by: Anish Ghulati <aghulati@...gle.com>
[sean: squash into one patch, write changelog]
