Subject: x86, mm: Use max_low_pfn for ZONE_NORMAL on 64-bit
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ece838b6257412647197c072fe59dfc6615df144;p=mv-sheeva.git

x86, mm: Use max_low_pfn for ZONE_NORMAL on 64-bit

64-bit has no highmem so max_low_pfn is always the same as
'max_pfn'.
