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. This patchset does the followings. - Some preparation work. Mainly importing header files to

Hi. This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was already merged to linux ia64 test branch. This patch is for linux ia64 test branch. This patchset does the followings. - Some preparation work. Mainly importing header files to define related structures. - Then, define functions related to hypercall which is the way to communicate with Xen hypervisor.
