It sounds like you're saying everything will be OK so long as each chunk of 64 bytes (cache line) is used together. But one page is typically 4 KB, and if you use for example all 64 bytes of one cache line, but only one cache line per page, you will suffer from TLB misses.

If you throw your computer out of window it may break. Why whould I access only 64 bytes per page? I suggest you to delete this comment.

We are not discussing VM here, I brought it as an analogy just to say cache lines are independent and need not be contineous.
