[Qemu-devel] [PATCH 10/11] memory: Fix old_portio vs non-zero offset.

[Richard Henderson]

The legacy functions that we're wrapping expect that offset
to be included in the register.  Indeed, they generally
expect the absolute address and then mask off the "high" bits.

The FDC is the first converted device with a non-zero offset.
