[IA64] SN fix for cpu hotplug/kexec
The sn_cpu_init() is required for cpu initialization on SN platforms.
Change __init to __cpuinit so that the function is not freed with init code/data.

[IA64] Save register stack contents on cpu start
The SN PROM uses the register stack in the slave loop. The contents
must be preserved for the OS to return to the slave loop via offlining
a cpu or for kexec. A 'flushrs" is needed to force the stack to be written
to memory prior to changing bspstore.

[IA64] Unwire set/get_robust_list
The syscalls set/get_robust_list must not be wired up until
futex_atomic_cmpxchg_inatomic is implemented. Otherwise the kernel will
hang in handle_futex_death.
