The handlers will be called when the undefined instruction and the processor state (as contained in pstate) match criteria used at registration.

AArch64 Linux kernel (including kernel threads) runs in EL1 mode using the SP1 stack. The vectors don't have a fixed address, only alignment (2^11) requirements.
