I am updating my git email settings to comply with the Xen development
guidelines. I am also asking my manager for permissions to set up git trees on

We will need to have a variable named pl2e when we rewrite
virt_to_xen_l2e. Change pl2e to l2t to reflect better its purpose.
This will make reviewing later patch easier.

The basic idea is like Persistent Kernel Map (PKMAP) in linux. We
pre-populate all the relevant page tables before system is fully set
up.
It is needed to bootstrap map domain page infrastructure -- we need
some way to map pages to set up per-cpu region without a direct map.

Previously, Wei Liu has created the patch series to switch to
alloc/map/unmap/free APIs for Xen page tables so that Xen page tables
are mapped with map_domain_page(). This is the first step towards
removing the direct map. I implemented patches on top of Wei's to remove

Not unmapping pages after map_xen_pagetable can leak the virtual address
space over time. Also this fix makes vmap_to_mfn non-trivial to be a

This is because a lot of code assumes that the rpt is in the direct map
region which is always mapped. Switching to domheap is non-trivial, so
