Pull misc build failure fixes from Mike Rapoport:
 "Fix min_low_pfn/max_low_pfn build errors on ia64 and microblaze.

  Some configurations of ia64 and microblaze use min_low_pfn and
  max_low_pfn in pfn_valid(). This causes build failures for modules
  that use pfn_valid().

  The fix is to add EXPORT_SYMBOL() for these variables on ia64 and
  microblaze"
