Subject: [PATCH v4 0/2] kunit: fail tests on UBSAN errors

v1 by Uriel is here: [1].
Since it's been a while, I've dropped the Reviewed-By's.

It depended on commit 83c4e7a0363b ("KUnit: KASAN Integration") which
hadn't been merged yet, so that caused some kerfuffle with applying them
previously and the series was reverted.

This revives the series but makes the kunit_fail_current_test() function
take a format string and logs the file and line number of the failing
code, addressing Alan Maguire's comments on the previous version.

As a result, the patch that makes UBSAN errors was tweaked slightly to
include an error message.

v2 -> v3:
  Try and fail to make kunit_fail_current_test() work on CONFIG_KUNIT=m
  s/_/__ on the helper func to match others in test.c
v3 -> v4:
  Revert to only enabling kunit_fail_current_test() for CONFIG_KUNIT=y
