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, Diffstat arch/x86/xen/Makefile | 2 +- drivers/xen/Makefile | 2 +-

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

Hi, Here is the third version of memory hotplug support for Xen guests patch. This one cleanly applies to git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git repository, xen/memory-hotplug head.

Hi Jeremy. According to your suggestion, I recreated patches for Ingo's x86.git tree. And this patch series includes Eddie's modification. Please review and forward them. (or push back to respin.) Recently the xen-ia64 community started to make efforts to merge xen/ia64 Linux to upstream. The first step is to merge up domU portion. This patchset is preliminary for xen/ia64 domU linux

Hi. This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was sent as another patchest. Changes from take 5 are rebased to Linux 2.6.26-rc3, bug fix ivt.S paravirtualization and multi entry point support. I believe these patches can be applied to the linux ia64 repository.

Hi. This patchset implements xen/ia64 domU support. Qing He and Eddie Dong also has been woring on pv_ops so that I want to discuss before going further and avoid duplicated work. I suppose that Eddie will also post his own patch. So reviewing both patches, we can reach to better pv_ops interface. - I didn't changed the ia64 intrinsic paravirtulization abi from the last post. Presumably it
