Not completely. The fix is attached.

Subject: Module parameter type fixes
The wrong version of the parmtype patch was merged, incompletely, and
the part that got merged got broken on the way. Here are the fixes:
Move __MODULE_INFO to modparam.h: This macro is used in modparam.h;
there are users who include this header but not module.h. The latter
includes modparam.h already.
__MODULE_INFO(parmtype, name##type, #name ":" #type) does not evaluate
to __MODULE_INFO(parmtype, footype, "foo:int") as was the idea, but to
__MODULE_INFO(parmtype, fooint, "foo:int") when type is bound to int.
In more complicated cases, we get syntax erros. Re-introduce the
__MODULE_PARM_TYPE macro; this is cleaner than renaming the type parameter.
Add the parmtype definition which was dropped during the merge to to the
obsolete but still heavily used MODULE_PARM macro.
