The function populate_pt_range is used to populate in advance the
page-table but it will not do the actual mapping. So passing the MFN in
parameter is pointless. Note that the only caller pass 0...
At the same time replace 0 by INVALID_MFNs. While this does not matter

This will avoid use of pfn_to_pdx(mfn_x(mfn)) over the code base.

The current prototype is slightly confusing because it takes a virtual
address and a physical frame (not address!). Switching to MFN will improve
safety and reduce the chance to mistakenly invert the 2 parameters.

In a follow-up patches, some callers will be switched to pass
INVALID_MFN instead of zero for non-present mappings. So skip
incrementing mfn if it is not a valid one.

A few files override page_to_mfn/mfn_to_page but actually never use
those macros. So drop them.

Hi all,
This is v6 of the series. For all the changes see in each patch.
To avoid the last patch (#16) to be a huge patch some files are converted to
use typesafe upfront. I have tried my best to push _mfn/mfn_x as down as
possible in the callers. Some of them was not feasible without major rewor
At the same time replace MFN 0 by INVALID_MFN or drop the initializer
when it is not necessary. This will make clearer that the MFN
initialized is not valid.
Other than MFN 0 -> INVALID_MFN, no functional change intended.

Most of the users of page_to_mfn and mfn_to_page are either overriding
the macros to make them work with mfn_t or use mfn_x/_mfn because the
rest of the function use mfn_t.
So make page_to_mfn and mfn_to_page return mfn_t by default. The __*
