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.
Oleg.
