@ptalbert @jlinton I have to admit I don't know much about these option and
I've only enabled what was essential to get Hyper-V guest working. My
(shallow) understanding is that we're trying to keep ARK as close to C9S as
possible and CONFIG_INPUT_MATRIXKMAP is disabled there. I, however, don't know
if we have plans to enable it for future RHELs, it would make sense to enable
it in ARK then. This can be a separate MR though.
