Hi,

Qemu currently uses 6 65k tables of pointers for handling ioports, which
makes 3MB on 64bit machines. There's a comment that says "XXX: use a two
level table to limit memory usage". But wouldn't it be more simple and
effective to just allocate them through mmap() and when a NULL pointer
is read, call the default handlers?
