Avi Kivity	acd1c812b5	Type-safe ioport callbacks The current ioport callbacks are not type-safe, in that they accept an "opaque" pointer as an argument whose type must match the argument to the registration function; this is not checked by the compiler. This patch adds an alternative that is type-safe. Instead of an opaque argument, both registation and the callback use a new IOPort type. The callback then uses container_of() to access its main structures. Currently the old and new methods exist side by side; once the old way is gone, we can also save a bunch of memory since the new method requires one pointer per ioport instead of 6.

Type-safe ioport callbacks

The current ioport callbacks are not type-safe, in that they accept an "opaque"
pointer as an argument whose type must match the argument to the registration
function; this is not checked by the compiler.

This patch adds an alternative that is type-safe.  Instead of an opaque
argument, both registation and the callback use a new IOPort type.  The
callback then uses container_of() to access its main structures.

Currently the old and new methods exist side by side; once the old way is gone,
we can also save a bunch of memory since the new method requires one pointer
per ioport instead of 6.
