In the submission we still use physical addresses because of lots of translation failures.

  1. Find reason:
    CPU is in user mode but the istream prefetcher requests translating kernel addresses.
  2. Fixed for now by not raising a page fault in that case
  3. Investigate the impact from TLB prefetching
