  ia64: fix min_low_pfn/max_low_pfn build errors (2020-09-01 19:34:11 +0300)

----------------------------------------------------------------
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.
