From 475c63bded322545d1e9ccc5930c8903d2c97c4c Mon Sep 17 00:00:00 2001 From: Horms Date: Mon, 5 Feb 2007 10:59:03 +0900 Subject: [IA64] Zero size /proc/vmcore on ia64 Set saved_max_pfn when discontig memory is in use. This sets up saved_max_pfn when disctontig memory is in use. This mirrors the code for contig memory. This patch does not entirely solve the problem of making vmcore work, however it does appear to be neccessary. Please consider applying.
