docs/ia64: Drop obsolete Xen documentation

While the xensource.com URLs referenced still exist, neither the Xen or Linux
2.6.18 fork have been touched since 2009, 11 years ago.  Other URLs are dead.

IA64 support was removed in Xen 4.2, in 2012.  Relegate this piece of
documentation to source history.

-********************************************************
-Recipe for getting/building/running Xen/ia64 with pv_ops
-********************************************************
-This recipe describes how to get xen-ia64 source and build it,
-and run domU with pv_ops.
-
-Requirements
-============
-
-  - python
-  - mercurial
-    it (aka "hg") is an open-source source code
-    management software. See the below.
-    http://www.selenic.com/mercurial/wiki/
-  - git
-  - bridge-utils
-
-Getting and Building Xen and Dom0
-=================================
-
-  My environment is:
-
-    - Machine  : Tiger4
-    - Domain0 OS  : RHEL5
-    - DomainU OS  : RHEL5
-
- 1. Download source::
-
-	# hg clone http://xenbits.xensource.com/ext/ia64/xen-unstable.hg
-	# cd xen-unstable.hg
-	# hg clone http://xenbits.xensource.com/ext/ia64/linux-2.6.18-xen.hg
-
- 2. # make world
-
- 3. # make install-tools
-
- 4. copy kernels and xen::
-
-	# cp xen/xen.gz /boot/efi/efi/redhat/
-	# cp build-linux-2.6.18-xen_ia64/vmlinux.gz \
-	/boot/efi/efi/redhat/vmlinuz-2.6.18.8-xen
-
- 5. make initrd for Dom0/DomU::
-
-	# make -C linux-2.6.18-xen.hg ARCH=ia64 modules_install \
-          O=$(pwd)/build-linux-2.6.18-xen_ia64
-	# mkinitrd -f /boot/efi/efi/redhat/initrd-2.6.18.8-xen.img \
-	  2.6.18.8-xen --builtin mptspi --builtin mptbase \
-	  --builtin mptscsih --builtin uhci-hcd --builtin ohci-hcd \
-	  --builtin ehci-hcd
-
-Making a disk image for guest OS
-================================
-
- 1. make file::
-
-      # dd if=/dev/zero of=/root/rhel5.img bs=1M seek=4096 count=0
-      # mke2fs -F -j /root/rhel5.img
-      # mount -o loop /root/rhel5.img /mnt
-      # cp -ax /{dev,var,etc,usr,bin,sbin,lib} /mnt
-      # mkdir /mnt/{root,proc,sys,home,tmp}
-
-      Note: You may miss some device files. If so, please create them
-      with mknod. Or you can use tar instead of cp.
-
- 2. modify DomU's fstab::
-
-      # vi /mnt/etc/fstab
-         /dev/xvda1  /            ext3    defaults        1 1
-         none        /dev/pts     devpts  gid=5,mode=620  0 0
-         none        /dev/shm     tmpfs   defaults        0 0
-         none        /proc        proc    defaults        0 0
-         none        /sys         sysfs   defaults        0 0
-
- 3. modify inittab
-
-    set runlevel to 3 to avoid X trying to start::
-
-      # vi /mnt/etc/inittab
-         id:3:initdefault:
-
-    Start a getty on the hvc0 console::
-
-       X0:2345:respawn:/sbin/mingetty hvc0
-
-    tty1-6 mingetty can be commented out
-
- 4. add hvc0 into /etc/securetty::
-
-      # vi /mnt/etc/securetty (add hvc0)
-
- 5. umount::
-
-      # umount /mnt
-
-FYI, virt-manager can also make a disk image for guest OS.
-It's GUI tools and easy to make it.
-
-Boot Xen & Domain0
-==================
-
- 1. replace elilo
-    elilo of RHEL5 can boot Xen and Dom0.
-    If you use old elilo (e.g RHEL4), please download from the below
-    http://elilo.sourceforge.net/cgi-bin/blosxom
-    and copy into /boot/efi/efi/redhat/::
-
-      # cp elilo-3.6-ia64.efi /boot/efi/efi/redhat/elilo.efi
-
- 2. modify elilo.conf (like the below)::
-
-      # vi /boot/efi/efi/redhat/elilo.conf
-      prompt
-      timeout=20
-      default=xen
-      relocatable
-
-      image=vmlinuz-2.6.18.8-xen
-             label=xen
-             vmm=xen.gz
-             initrd=initrd-2.6.18.8-xen.img
-             read-only
-             append=" -- rhgb root=/dev/sda2"
-
-The append options before "--" are for xen hypervisor,
-the options after "--" are for dom0.
-
-FYI, your machine may need console options like
-"com1=19200,8n1 console=vga,com1". For example,
-append="com1=19200,8n1 console=vga,com1 -- rhgb console=tty0 \
-console=ttyS0 root=/dev/sda2"
-
-Getting and Building domU with pv_ops
-=====================================
-
- 1. get pv_ops tree::
-
-      # git clone http://people.valinux.co.jp/~yamahata/xen-ia64/linux-2.6-xen-ia64.git/
-
- 2. git branch (if necessary)::
-
-      # cd linux-2.6-xen-ia64/
-      # git checkout -b your_branch origin/xen-ia64-domu-minimal-2008may19
-
-   Note:
-     The current branch is xen-ia64-domu-minimal-2008may19.
-     But you would find the new branch. You can see with
-     "git branch -r" to get the branch lists.
-
-       http://people.valinux.co.jp/~yamahata/xen-ia64/for_eagl/linux-2.6-ia64-pv-ops.git/
-
-     is also available.
-
-     The tree is based on
-
-      git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6 test)
-
- 3. copy .config for pv_ops of domU::
-
-      # cp arch/ia64/configs/xen_domu_wip_defconfig .config
-
- 4. make kernel with pv_ops::
-
-      # make oldconfig
-      # make
-
- 5. install the kernel and initrd::
-
-      # cp vmlinux.gz /boot/efi/efi/redhat/vmlinuz-2.6-pv_ops-xenU
-      # make modules_install
-      # mkinitrd -f /boot/efi/efi/redhat/initrd-2.6-pv_ops-xenU.img \
-        2.6.26-rc3xen-ia64-08941-g1b12161 --builtin mptspi \
-        --builtin mptbase --builtin mptscsih --builtin uhci-hcd \
-        --builtin ohci-hcd --builtin ehci-hcd
-
-Boot DomainU with pv_ops
-========================
-
- 1. make config of DomU::
-
-     # vi /etc/xen/rhel5
-       kernel = "/boot/efi/efi/redhat/vmlinuz-2.6-pv_ops-xenU"
-       ramdisk = "/boot/efi/efi/redhat/initrd-2.6-pv_ops-xenU.img"
-       vcpus = 1
-       memory = 512
-       name = "rhel5"
-       disk = [ 'file:/root/rhel5.img,xvda1,w' ]
-       root = "/dev/xvda1 ro"
-       extra= "rhgb console=hvc0"
-
- 2. After boot xen and dom0, start xend::
-
-	# /etc/init.d/xend start
-
-   ( In the debugging case, `# XEND_DEBUG=1 xend trace_start` )
-
- 3. start domU::
-
-	# xm create -c rhel5
