[PATCH v2 0/3] ubsan: Split out bounds checker

[Kees Cook]

v2:
    - clarify Kconfig help text (aryabinin)
    - add reviewed-by
    - aim series at akpm, which seems to be where ubsan goes through?
v1: https://lore.kernel.org/lkml/20191120010636.27368-1-keescook@xxxxxxxxxxxx

This splits out the bounds checker so it can be individually used. This
is expected to be enabled in Android and hopefully for syzbot. Includes
LKDTM tests for behavioral corner-cases (beyond just the bounds checker).

  ubsan: Add trap instrumentation option
