[Xen-devel] [PATCH 0/6] xen/arm: Xen save/restore/live migration support

[Wei Huang <w1.huang@xxxxxxxxxxx>]

The following are the save/restore/live-migration patches I forward-ported to 
the latest Xen tree. Note that I kept the order of original patches, and 
Signed-off-by as well. For the patches I modified (see summary below), I
added my name as Signed-off-by.

These patches aren't intended as the final version. Since Junghyun Yoo is 
working on his patches, I think it is better to send out my version now 
for discussion and proper merge. Let us make Xen 4.5 support these features.

=== Modification Summary ===

Patch 1: 
* Adapt to latest Xen source code
* Setting IRQ status as enabled by checking ieanble bits after loading VM info
* Minor fixes to support 64-bit

Patch 5:
* Add new p2m ARM type (p2m_ram_logdirty) to support dirty page tracking

Patch 6:
* Enable save/restore/live migration support based on latest Xen code
* Adapt to latest Xen source code
