From d8bd9a121c2f2bc8b36da930dc91b69fd2a705e2 Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Wed, 11 Nov 2020 15:53:20 +0100 Subject: [PATCH] powerpc/book3s64/hash: Drop WARN_ON in hash__remove_section_mapping() The single caller (arch_remove_linear_mapping()) prints a proper warning when this function fails. No need to eventually crash the kernel - let's drop this WARN_ON.
