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. Also compile tested on x86-64 and arm64 with gcc this time around.

Patch 1/2 adds a guard around noinstr that matches upstream, to prevent a build issue, and has some minor context conflicts. Patch 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.

Ok, trying this again, let's see what breaks :)

thanks,
