Hmmm, I'm wondering if I'm seeing unrelated breakages.
Applied these patches on top of 55ba0fe059a5 ("Merge tag
'for-5.13-tag' of
git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux")

$ make mrproper
$ rm -rf .kunit/* # just in case
$ ./tools/testing/kunit/kunit.py run --arch=arm64
...
ERROR:root:arch/arm64/Makefile:25: ld does not support
--fix-cortex-a53-843419; kernel may be susceptible to erratum
arch/arm64/Makefile:44: Detected assembler with broken .inst;
disassembly will be unreliable
gcc: error: unrecognized command-line option ‘-mlittle-endian’

So it seems like my version of ld might be out of date, but my gcc is 10.2.1
Is there a minimum version of the toolchain this would expect that we
can call out in the commit message (and in the Documentation)?

--arch=x86_64 worked just fine for me, however, which is mainly what I
was interested in.

I've mainly just left some nits and comments regarding typechecking.

optional: perhaps add "(e.g. x86_64, um)"
Most people using this would be able to infer that, but I prefer
strings that are basically enums to document examples of useful
values.
(And x86 is probably the one most people want to use this flag for).

I might be missing something, but do we need this?

w => a means we wouldn't truncate the file if it exists. I can imagine
I'm missing something that makes it necessary.
+ => opens for read/write: we don't do any reads with f afaict.

nit: let's annotate these as `linux_arch: str, cross_compile: str` (or
is it Optional[str] here?)
I can see a reader thinking arch might be an enum and that
cross_compile might be a bool.

pytype complains about this.
You'd want `+ str(e)`

Oh my.
I don't know enough to say if there's a better way of doing this.

But I think we should probably split this out into a separate python
file, if this mapping remains necessary.
E.g. in a qemu_configs.py file or the like.

I've called out the two errors pytype gives already, but mypy is even
worse about this new class :(

So to make up for mypy being less smart, we can do this and get it down 2 errors

ditto, a debug statement?
Though this one could be useful to actually print out for the user if
we include some more context in the message.

Minor note: pytype doesn't like this.
The code is correct, but pytype can't figure out that ops can't be the
QEMU variant.

Pytype recognizes comments like " # pytype: disable=attribute-error"
but mypy doesn't.
So I don't know that there's a way we can make both of them happy :/
