[Xen-devel] [PATCH V3 0/1] support >3 level p2m tree

Pv domains write the mfn of a 3 level p2m tree to arch_shared_info
structure. Consumers of this information are the domain save/restore
functions of the Xen tools.

Being defined as having 3 levels the maximum supported domain size of
64 bit domains is 512 GB. The following patch expands the
arch_shared_info structure to support more levels.

The Xen tools are not covered in this patch as the patch series
"Libxl migration v2 support":
should be applied first.

Juergen Gross (1):
  expand x86 arch_shared_info to support >3 level p2m tree
