From 995761627d97cc374f14203589b3a6385019bf0b Mon Sep 17 00:00:00 2001 From: Dmitry Vyukov Date: Wed, 30 Nov 2016 15:54:13 -0800 Subject: kasan: update kasan_global for gcc 7 commit 045d599a286bc01daa3510d59272440a17b23c2e upstream. kasan_global struct is part of compiler/runtime ABI. gcc revision 241983 has added a new field to kasan_global struct. Update kernel definition of kasan_global struct to include the new field. Without this patch KASAN is broken with gcc 7.
