Subject: [for-stable-4.19 PATCH 0/2] Backport patches to fix KASAN+LKDTM with recent clang on ARM64


Backport 2 patches that are required to make KASAN+LKDTM work
with recent clang (patch 2/2 has a complete description).
Tested on our chromeos-4.19 branch.

Patch 1/2 is context conflict only, and 2/2 is a clean backport.

These patches have been merged to 5.4 stable already. We might
need to backport to older stable branches, but this is what I
could test for now.
