Add compat macros to use either old or new helpers depending on used kernel source version.

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths

Hi. This patchset is ia64/xen domU patch take 8 which was updated following Tony's review. (Thank you very much, Tony.) This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was sent as another patchest. This patchset is for linux ia64 test branch and depends on some patches for xen common part I'll send separately. To compile, the changesets in x86/xen

This patchset is ia64/xen domU patch take 9 which is rebased to 2.6.26 This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was sent as another patchest. 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
