# 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. # # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version #
