From 576fc0978b6b3673fce6d4b405f36449e508826c Mon Sep 17 00:00:00 2001 From: Ravikiran G Thirumalai Date: Thu, 29 Dec 2005 13:06:11 +0100 Subject: [PATCH] [PATCH] x86_64: Fix incorrect node_present_pages on NUMA 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.
