From abfe8026b505d66dad7a3e5ebe7235f12c29b67d Mon Sep 17 00:00:00 2001 From: Alistair Popple Date: Mon, 10 Apr 2017 15:24:35 +1000 Subject: [PATCH] powerpc/powernv: Require MMU_NOTIFIER to fix NPU build In the recent commit 1ab66d1fbada ("powerpc/powernv: Introduce address translation services for Nvlink2") the NPU code gained a dependency on MMU notifiers. All our defconfigs have KVM enabled, which selects MMU_NOTIFIER, but if KVM is not enabled then the build breaks. Fix it by always selecting MMU_NOTIFIER when we're building powernv.
