Subject[PATCH v4 0/6] ubsan: Split out bounds checker
Date
This splits out the bounds checker so it can be individually used. This
is enabled in Android and hopefully for syzbot. Includes LKDTM tests for
behavioral corner-cases (beyond just the bounds checker), and adjusts
ubsan and kasan slightly for correct panic handling.

v4:
- use hyphenated bug class names (andreyknvl)
- add Acks
