From 2f76969f2eef051bdd63d38b08d78e790440b0ad Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Thu, 10 Mar 2016 18:30:56 +0000 Subject: [PATCH] arm64: kasan: Use actual memory node when populating the kernel image shadow With the 16KB or 64KB page configurations, the generic vmemmap_populate() implementation warns on potential offnode page_structs via vmemmap_verify() because the arm64 kasan_init() passes NUMA_NO_NODE instead of the actual node for the kernel image memory.
