83 Fetches a byte of data from the user-space address
85 The byte read is zero-extended into the results variable.
87 Fetches a word of data (long) from the user-space address
90 Fetches 16 bits of data from the user-space address
92 The half-word read is zero-extended into the results variable.
94 Fetches 32 bits of data from the user-space address
97 Fetches 64 bits of data from the user-space address
100 Fetches a word of data (long) from the user-space address
105 Fetches 32 bits of data from the user-space address
