From: Olaf Hering Date: Mon, 1 Oct 2012 19:18:01 +0000 (+0200) Subject: xen pv-on-hvm: add pfn_is_ram helper for kdump X-Git-Tag: v3.7-rc1~33^2~3 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=34b6f01a79bd65fbd06511d2cb7b28e33a506246;p=pandora-kernel.git xen pv-on-hvm: add pfn_is_ram helper for kdump Register pfn_is_ram helper speed up reading /proc/vmcore in the kdump kernel. See commit message of 997c136f518c ("fs/proc/vmcore.c: add hook to read_from_oldmem() to check for non-ram pages") for details. It makes use of a new hvmop HVMOP_get_mem_type which was introduced in xen 4.2 (23298:26413986e6e0) and backported to 4.1.1. The new function is currently only enabled for reading /proc/vmcore. Later it will be used also for the kexec kernel. Since that requires more changes in the generic kernel make it static for the time being.
