 Or __PA_ADDR in paccess.h.

 I have mixed feelings, the reason for __stringify being absent is the 
macro being generic and more recently added than pieces of code that use 
STR, e.g. unaligned.c that has been there since forever.  And we do use 
__stringify in many other cases.

 On the other hand STR is short and sweet, unlike __stringify.

 So how about adding a macro like __STR_PTR that expands to 
__stringify(PTR) and converting all the places throughout our port 
(including ones currently using __UA_ADDR/__PA_ADDR) to use the new macro?

 Leonid's bug fix will need to go in first of course.
