CONFIG_SOFTMMU should be reserved for the actual softmmu tlb, which we *should* be able to 
enable for user-only.  It is the only way to handle some of our host/guest page size 
problems.  Further, CONFIG_SOFTMMU should go away as a #define and become a runtime test 
(forced to true for system mode).  Pie in the sky stuff.

It is quite likely that all uses of CONFIG_SOFTMMU outside of tcg/, accel/tcg/, and random 
bits of include/ should only be using CONFIG_USER_ONLY.
