/*
* Reads a word but traps failed faults
*
* This is similar to fuword() but rather than returnin
* the word, the second argument points to the location
* to store the word in. The function returns 0 for
* suceess and -1 for failure.
* This routine is used to fetch a word from user space
* when the value being fetched could be -1. By separating
* error flagging from the return value this is achieved.
* This function is used by the prefetch abort handler
*
* r0 - address to read
* r1 - address to store result
