[PATCH v2 2/2] arch/powerpc/kvm: kvmppc_hv_entry: remove r4 argument

kvmppc_hv_entry is called from only 2 locations within book3s_hv_rmhandlers.S. Both of those locations set r4 as HSTATE_KVM_VCPU(r13) before calling kvmppc_hv_entry. So, shift the r4 load instruction to kvmppc_hv_entry and thus modify the calling convention of this function. Signed-off-by: Kautuk
