[Xen-devel] [PATCH v2 0/3] x86: per-domain mapping adjustments

["Jan Beulich" <JBeulich@xxxxxxxx>]

The main goal being the re-work of the hypercall argument translation
area management, this series first breaks out per-domain mapping
management into its own set of functions, in order to then use this
for setting up the translation areas in per-domain space.

While doing this I also realized that it's pointless for the
map_domain_page() code to track L1 page table pointers in a
separate Xen heap page - we can equally well use the linear
page table for the manipulations needed here.

1: introduce create_perdomain_mapping()
2: rework hypercall argument translation area setup
3: use linear L1 page table for map_domain_page() page table manipulation
