New in this version: - use opaque instead of container_of() in memory callbacks - turns out those container_of()s were hindering reuse - I/O space access via memory API - PCI fully converted - except bridge, which actually benefits most from the conversion - ioeventfd support Caveats: - some devices still grab a global memory region instead of inheriting it from their bus. Seen in the code as #include "exec-memory.h" - the conversion from separate b/w/l functions to a single function with a size argument sometimes yields ugly dispatch functions. In some cases I eliminated them, in others I left it to the device maintainer. I also have an idea now how to kill off the page descriptor - use a page table like x86, but with no offset bits, have a variable tree height and allow any level to be a "large page". This results in most accesses terminating after one or two lookups. MMIO will tend to take more (three to five, depending on tree width), but they will be cached. The subpage logic can be completely eliminated with this.
