During the interrupt registration comparison is made against
max value of exception types for ARMV7, but in the common handling
function the check is made against max value of exceptions types
for ARMV8. This can lead to undefined behaviour during registration
of interrupts.
This patch modifies the registration function to handle only AArch64
exceptions.
