Subject: [PATCH 0/3] Extend KCSAN to all powerpc

This series enables KCSAN on all powerpc.

To do this, a fix is required to KCSAN core.

Once that fix is done, the stubs can also be removed from xtensa.

It would be nice if patch 1 could go in v6.4 as a fix, then patches 2 and 3
could be handled separately in each architecture in next cycle.

Christophe Leroy (2):
  kcsan: Don't expect 64 bits atomic builtins from 32 bits architectures
  xtensa: Remove 64 bits atomic builtins stubs
