It's how we handle similar cases for other targets.
And we actively get it wrong, e.g. mips.
So I have patches to move that code *out* of linux-user.
We have macros in

The real kernel has to load the instruction and extract
the imm5 field; for qemu, modify the translator to do this.

the other trap numbers as per the kernel's trap_table.
