This part of the patch is approved, but please add a sentence to
explain what would be the effect of declaring a region `void' on GDB's
operation, from the user's point of view.  It strikes me that this
text, from the beginning of your message:

> Add "void" attribute, which disallows both read & write access.  This
> useful for guarding holes in a target's address space that cause the
> system to hang when read/written.

is exactly what would make this attribute's effect crystal-clear ;-)
