Automatic task placement by the scheduler would mean giving up the
requirement that the user-space affinity mask must always be honoured.
Is that on the table?

Killing aarch32 tasks with an empty intersection between the user-space
mask and aarch32_mask is not really "automatic" and would require the
aarch32 capability to be exposed anyway.
