From e269d269e0b53a7a6cb1d04290f8174bf0488cb4 Mon Sep 17 00:00:00 2001 From: "Sachin P. Sant" Date: Fri, 8 Sep 2006 07:59:52 +0530 Subject: [PATCH] [POWERPC] kdump: Support kernels having 64k page size. This is required to generate proper core files using kdump on ppc64. Create a backup region of 64K size irrespective of the PAGE SIZE. At present 32K was used as backup size. In the case of 64K page size, second PT_LOAD segments starts at 32K and the first one is not page aligned. __ioremap() (crash_dump.c) fails if pfn = 0 which is the case for the second PT_LOAD segment. This is not an issue for 4K page size because the the first page (32K backup) is copied to second kernel memory and thus referencing with the second kernel pfn.
