what is the purpose to expose VSESR_EL2?
do you mean set its value after migration?

May be we can use similar below Mechanism
https://www.spinics.net/lists/arm-kernel/msg603525.html

when user-space sync the register status, it will get these register value.
it will reuse the IOCTL KVM_GET_ONE_REG and no need to add extra API.
