 Hmm, documentation on ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE seems rather 
scarce, but based on my guess shouldn't this be "if !EVA"?

ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE means the any given virtual
address in a task context can either be a valid kernel or user address
space, but not both.

Note that the bpf probe really is a legacy use case and should not be
used in new code independent of that.
