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.
Mark Rutland (1): lkdtm: don't move ctors to .rodata
