When trying to return to ARCBios on a 32 bit ARCBios machine (such as the O2),
disable interrupts and unconditionnaly use proc0 u area as the stack, so that
once ARCBios loses the upper 32 bits of the stack pointer, accessing the
stack does not fault (proc0 u area is allocated in CKSEG0 for this reason).
