| You need these too, I think:

|     exec: skip MMIO regions correctly in 
cpu_physical_memory_write_rom_internal
|     exec: clamp accesses against the MemoryRegionSection
|     exec: do not clamp accesses to MMIO regions
|     exec: Respect as_translate_internal length clamp
|     ioport: reserve the whole range of an I/O port in the AddressSpace
|     ioport: loosen assertions on emulation of 16-bit ports
|     ioport: remove wrong comment
|     ide: there is only one data port
|     gus: clean up MemoryRegionPortio
|     sb16: remove useless mixer_write_indexw

  Ie. all these also need to be pulled into versions <= v2.3.1, right? 
Otherwise the segfault issue seems to be cured by commit - '23820dbfc79d1c9'

  Okay, I'll go through the archives and confirm here.

Thank you.
