The code fragment presented in the RowHammer paper has a core loop of LOAD row1/LOAD row2/CLFLUSH row1/CLFLUSH row2/MFENCE. In the memtest86+ test environment, with each statement as a separate expression, there were other extraneous memory references in the core loop that may be confounding the memory access pattern. Remove them by using a raw .S file.
