[Xen-devel] [PATCH v6 0/5] xen/arm: live migration support in arndale board

[Junghyun Yoo <yjhyun.yoo@xxxxxxxxxxx>]

Hello!
here goes the v6 patch series. The major changes in this version are the 
following:

   1) Move VLPT address range to the back of the domain heap so each pcpu has 
it's
      own mapping of VLPT.

   2) For preparing VLPT, rather than making a copy of p2m first, just hold a 
mapping
      to the p2m first.

          Patch 1 implements hvm save/restore (including vcpu).

          Patch 2 implements 'modify_returncode' for switching the return value 
of suspend hypercall from domU.

          Patch 3 implements base functions for VLPT.

          Patch 4 implements dirty-page tracing by using VLPT.

          Patch 5 implements the toolstack part for live migration of ARM.

Bests,
Junghyun Yoo
