Virtual memory manager does not initiate page fault #12

Closed vodozhaba closed 7 years ago

vodozhaba commented 7 years ago

Try running this:

    int* ptr = (int*) 0xFFFFFFF0;
    int val = *ptr;

It won't crash, although corresponding frames aren't mapped.

Well, I've resolved this feature, but now it initiates page fault on boot. But that's a separate issue.
