Alright, I incorporated all the above into a patchset that I think is
ready to send out, but I had a couple of issues with the above
suggestions:

Thanks a lot for those suggestions.

- I could not find a config which causes a stacksize warning for
sdhci-of-aspeed.

I keep a history of my randconfig builds. This one only happened
once before I fixed it, it may depend on some other combination of
options. See my original defconfig file at
https://pastebin.com/raw/XJxjVGYa
rand/0xAB2DD5A0-failure:/git/arm-soc/drivers/mmc/host/sdhci-of-aspeed-test.c:47:1:

- test_scanf is not a KUnit test.

I have three defconfigs for this one, all on x86-64:

rand86/0x30AD57FB-failure:/git/arm-soc/lib/test_scanf.c: In function
'numbers_list_field_width_val_width':

https://pastebin.com/raw/jUdY6d3G is the worst one of those

- Linus already fixed the thunderbolt test by breaking up the test cases.

Ok.

quoted

I am going to send out patches for the thunderbolt test and for the
sdhci-of-aspeed test for the sake of completeness, but I am not sure
if we should merge those two. I'll let y'all decide on the patch
review.

Just in case I missed any interested parties on this thread, I posted
my patches here:

https://lore.kernel.org/linux-kselftest/20210917061104.2680133-1-brendanhiggins@google.com/T/#t (local)

Thanks! I'll reply to the particular patch as well, but I don't think
that this is
sufficient here:

+CFLAGS_bitfield_kunit.o := $(call
cc-option,-Wframe-larger-than=10240) $(DISABLE_STRUCTLEAK_PLUGIN)

If 10KB is actually needed, this definitely overflows the 8KB stack on
32-bit architectures.
