#     Merge tag 'fixes-2020-09-03' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock
#     
#     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"
