Subject: ia64: sn_nodepda cannot be assigned to after this_cpu conversion. Use __this_cpu_write.
There must be an explit statement to modify the percpu variable after the conversion of the
sn_nodpda macro to use this_cpu_read.

Too bad there is no ia64 support in qemu; this could use some "real" testing.
