Unfortunately it is more complicated to write to the CPU memory. In particular, specific action should be done when translated code is present. A consistent API must include something like cpu_page_lock() / unlock(). Look at cpu_physical_memory_rw() to see the various issues which must be handled. Moreover, it would be better to add bus specific APIs (at least for PCI), but I can accept a CPU memory API for now. Fabrice.
