[PATCH 0/3] xen: more portability patches
Hi Jeremy.
Here are the 3 patches for ia64/xen support.
The first one is just to move manage.c under drivers/xen.
This is trivial.
The second and third ones are for compilation fix on ia64.
You may want to postpone those 2 patches to make your merge task
easy as you said before.
thanks,

[PATCH] make balloon driver not return pages which are in [xen_start_info->nr_pages, max_pfn] on ia64
make balloon driver not return pages which are in
[xen_start_info->nr_pages, max_pfn] on ia64.
On ia64 memory might be assigned sparsely. In that case
xen_start_info->nr_pages and max_pfn doesn''t match while pages which are in
[xen_start_info->nr_pages, max_pfn] are used.

[RFC 00/14] arm: implement ballooning and privcmd foreign mappings based on x86 PVH
This series implements ballooning for Xen on ARM and builds and Mukesh''s
PVH privcmd stuff to implement foreign page mapping on ARM, replacing
the old "HACK: initial (very hacky) XENMAPSPACE_gmfn_foreign" patch.
The baseline is a bit complex, it is basically Stefano''s xenarm-forlinus
branch (commit bbd6eb29214e) merged with Konrad''s linux-next-pvh branch
