USER_FLAGS is used in process.c/arch_setup_user_stack() to prepare the processor status word (PSW) for a context switch. Currently bits 15-14 are set to '0' which conflicts with the NEC V25 CPU (switches to undefined register bank on next contrext switch). As these bits are not used for other CPUs it can be set to '1'.
