Subject: [PATCH v2 0/3] Bitops instrumentation for KASAN

The previous version of this patch series and discussion can be found

The most significant change is the change of the instrumented access
size to cover the entire word of a bit.

Marco Elver (3):
  lib/test_kasan: Add bitops tests
  x86: Move CPU feature test out of uaccess region
  asm-generic, x86: Add bitops instrumentation for KASAN
