We try to free the pagetable pages once we've unmapped our portion.

In case we encounter an error during the mapping of a region, we want to
unwind what we've established so far exactly the way we did the mapping.
This is the PUD part kept deliberately small for easier review.

... and use the good old standard defines which we all know. Also,
simplify math to shift by PAGE_SHIFT instead of multiplying by
PAGE_SIZE.

Add the ability to map pages in an arbitrary pgd. This wires in the
remaining stuff so that there's a new interface with which you can map a
region into an arbitrary PGD.

This allocates, if necessary, and populates the corresponding PGD entry
with a PUD page. The next population level is a dummy macro which will
be removed by the next patch and it is added here to keep the patch
small and easily reviewable but not break

Hi all,
here's finally a new version of the runtime services VA mapping patchset
which hopefully implements hpa's idea of statically mapping EFI runtime
regions in a top-down manner starting at -4Gb virtual.
We're also using a different pagetable so as not to

This is preparatory work in order to be able to map pages into a
specified PGD and not implicitly and only into init_mm.

Handle last level by unconditionally writing the PTEs into the PTE page
while paying attention to the NX bit.

Add the next level of the pagetable populating function, we handle
chunks around a 1G boundary by mapping them with the lower level
functions - otherwise we use 1G pages for the mappings, thus using as
less amount of pagetable pages as possible.
