From 62ccf5bf1f4704986844440069df70b6509a9213 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Mon, 2 May 2016 18:26:07 +0530 Subject: [PATCH] powerpc/mm/slice: Remove slice_mm_new_context() The usage in mm mmu_context_nohash.c is bogus, because we set the context.id value to MMU_NO_CONTEXT 4 lines previously in the same function, meaning slice_mm_new_context() will always be true. The book3s 64 usage was removed in the previous commit. So remove it as unused.
