- adjust the example init state such that it does not constrain the
value of physBase and kernelELFBase too much. We assume 4M physical
memory and 4k of kernel ELF memory. We need 4M for the infoflow
example, because it requires a 2M RISCVLargePage plus additional
kernel objects.
- make the PagePTE for kernelELFBase point to kernelELFPAddrBase so
that the mapping stays consistent when physBase changes.
- introduce shorthand constants for the index in the page table that
is responsible for kernelELFBase, and for the number of bits left
to translate from the top-level page table (= size of the pages in
that table).
