[PATCH v2] powerpc: move hmi.c to arch/powerpc/kvm/
From: Paolo Bonzini <pbonzini@redhat.com>
Date: 2016-08-11 13:07:52
hmi.c functions are unused unless sibling_subcore_state is nonzero, and
that in turn happens only if KVM is in use. So move the code to
arch/powerpc/kvm/, putting it under CONFIG_KVM_BOOK3S_HV_POSSIBLE
rather than CONFIG_PPC_BOOK3S_64. The sibling_subcore_state is also
included in struct paca_struct only if KVM is supported by the kernel.

v1->v2: use CONFIG_KVM_BOOK3S_HV_POSSIBLE, not
CONFIG_KVM_BOOK3S_64_HANDLER. The former implies
the latter, but the reverse is not true.
