It did surprise me though, since I would have expected something to use hflags.  It turns 
out the only thing that uses TRICORE_HFLAG_* is the kernel vs user-mode bits.

Bastian, there is code missing from cpu_get_tb_cpu_state, to copy env->PSW[11:10] to 
*flags.  At present it would seem that all code effectively runs in kernel mode.
