Replacement for CONFIG_DEBUG_IOVIRT?

[William F. Acker WB2FLW [phone]]

Hi all,

I'm patching the kernel with Speakup
http://linux-speakup.org/.
Due to a bug in the patch, it was necessary to disable CONFIG_DEBUG_IOVIRT 
in order to  get the kernel to compile.  In 1.116, the option is missing.  
Does anyone know the name of the option that replaced it?
          TIA.
