[Qemu-devel] [RFC][PATCH 00/15] Refactor portio dispatching

[Jan Kiszka]

This series converts the remaining users of register_ioport* to portio
lists, simplifies the handling of subpages and adds support for unaligned
memory region accesses. Then it replaces the current portio dispatcher
with the existing one for MMIO and removes several lines of code. This
also allows to build BQL-free portio on top once we enhance the memory
layer accordingly.

Seems to work fine so far but surely requires thorough review. And I
would welcome early comments on the direction.
