I obviously do not know how difficult is to support the compat tasks, and
in any case I leave this to you and Will.

But if this is not simple, perhaps the initial implementation could simply
nack the probe in arch_uprobe_analyze_insn() if this mm is not 64-bit.
Although I do not see something like is_64bit_mm() in arch/arm64... So may be
the first version can even ignore this problem and just document the fact
that AArch32 tasks are not supported.
