KVM: PPC: Book3S HV: radix: Fix uninitialized var build error
Old GCCs (4.6.3 at least), aren't able to follow the logic in __kvmhv_copy_tofrom_guest_radix() and warn that old_pid is used uninitialized: arch/powerpc/kvm/book3s_64_mmu_radix.c:75:3: error: 'old_pid' may be used uninitialized in this function The logic is OK, we only use old_pid if quadrant == 1, and in that case it has definitely be initialised, eg: if (quadrant == 1) { old_pid = mfspr(SPRN_PID); ... if (quadrant == 1 && pid != old_pid) mtspr(SPRN_PID, old_pid); Annotate it to fix the error.
