- * Testcase: Test the CS prefetch behaviour on batches
- *
- * Historically the batch prefetcher doesn't check whether it's crossing page
- * boundaries and likes to throw up when it gets a pagefault in return for his
- * over-eager behaviour. Check for this.

- * This test for a bug where we've failed to plug a scratch pte entry into the
