[PATCH] x86_64: Fix incorrect node_present_pages on NUMA
Ravikiran G Thirumalai [Thu, 29 Dec 2005 12:06:11 +0000 (13:06 +0100)]
Currently, we do not pass the correct start_pfn to e820_hole_size, to
calculate holes.  Following patch fixes that.

The bug results in incorrect number of node_present_pages for each pgdat
and causes ugly output in /sys and probably VM inbalances.
