Not in RT:

#ifdef CONFIG_PREEMPT_RT_FULL
# define STACKFAULT_STACK 0
# define DOUBLEFAULT_STACK 1
# define NMI_STACK 2
# define DEBUG_STACK 0
# define MCE_STACK 3
# define N_EXCEPTION_STACKS 3  /* hw limit: 7 */
#else
# define STACKFAULT_STACK 1
# define DOUBLEFAULT_STACK 2
# define NMI_STACK 3
# define DEBUG_STACK 4
# define MCE_STACK 5
# define N_EXCEPTION_STACKS 5  /* hw limit: 7 */
#endif
