Hi, This set of patches contains initial kexec/kdump implementation for Xen v2 (previous version were posted to few people by mistake; sorry for that). Currently only dom0 is supported, however, almost all infrustructure required for domU support is ready. Jan Beulich suggested to merge Xen x86 assembler code with baremetal x86 code. This could simplify and reduce a bit size of kernel code.

vmcoreinfo file could exists under /sys/kernel (valid on baremetal only) and/or under /sys/hypervisor (valid when Xen dom0 is running). Read only one of them. It means that only one PT_NOTE will be always created. Remove extra code for second PT_NOTE creation.

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
