4.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Ulf Magnusson <ulfalizer@xxxxxxxxx> commit 57ea5f161a7de5b1913c212d04f57a175b159fdf upstream. Commit 76d837a4c0f9 ("KVM: PPC: Book3S PR: Don't include SPAPR TCE code on non-pseries platforms") added a reference to the globally undefined symbol PPC_SERIES. Looking at the rest of the commit, PPC_PSERIES was probably intended. Change PPC_SERIES to PPC_PSERIES. Discovered with the https://github.com/ulfalizer/Kconfiglib/blob/master/examples/list_undefined.py script.
