[IA64] IA64 Kexec/kdump
Changes and updates. 1. Remove fake rendz path and related code according to discuss with Khalid Aziz. 2. fc.i offset fix in relocate_kernel.S. 3. iospic shutdown code eoi and mask race fix from Fujitsu. 4. Warm boot hook in machine_kexec to SN SAL code from Jack Steiner. 5. Send slave to SAL slave loop patch from Jay Lan. 6. Kdump on non-recoverable MCA event patch from Jay Lan 7. Use CTL_UNNUMBERED in kdump_on_init sysctl. Signed-off-by: Zou Nan hai <nanhai.zou@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

+ kexec is a system call that implements the ability to shutdown your
+ current kernel, and to start another kernel. It is like a reboot
+ but it is indepedent of the system firmware. And like a reboot
+ you can start any kernel with it, not just Linux.
+
+ The name comes from the similiarity to the exec system call.
+
+ It is an ongoing process to be certain the hardware in a machine
+ is properly shutdown, so do not be surprised if this code does not
+ initially work for you. It may help to enable device hotplugging
+ support. As of this writing the exact hardware interface is
+ strongly in flux, so no good recommendation can be made.
