   [IA64] sn2_defconfig: disable hotplug cpu
   
   Looks like there are some bugs that won't be fixed before 2.6.9 in the
   scheduling domain code wrt HOTPLUG_CPU, so I'm disabling it in sn2_defconfig
   (we don't support CPU hotplug just yet anyway).

   [IA64] cleanup contig/discontig/virt_mem_map macros
   
   I got this patch from Zou Nan hai to resolve the problem that
   Andrew Morton has been having booting his ia64 system.  The code
   is quite a bit cleaner as he has reduced the number of different
   definitions of pfn_valid/page_to_pfn/pfn_to_page, and left the
   only remaining ones next to each other in page.h ... so this
   should be easier to maintain going forward.
