kvmppc_hv_entry isn't called from anywhere other than book3s_hv_rmhandlers.S itself. Removing .global scope for this function and annotating it with SYM_CODE_START_LOCAL and SYM_CODE_END.
Does removing .global introduce the objtool warning, or was it already present? Just trying to understand if this is two changes or one (not that it really matters, maybe just for the purpose of the changelog). Since the patch only touches KVM, subject should follow arch/powerpc/kvm convention, which is not the same as the rest of arch/powerpc. KVM: PPC: Book3S HV: Otherwise seems okay Reviewed-by: Nicholas Piggin <npiggin@gmail.com> Thanks, Nick
