From: "Vivek Goyal" <vgoyal@in.ibm.com> o Support for /proc/vmcore interface. This interface exports elf core image either in ELF32 or ELF64 format, depending on the format in which elf headers have been stored by crashed kernel. o Added support for CONFIG_VMCORE config option. o Removed the dependency on /proc/kcore. From: "Eric W. Biederman" <ebiederm@xmission.com> This patch has been refactored to more closely match the prevailing style in the affected files. And to clearly indicate the dependency between /proc/kcore and proc/vmcore.c From: Hariprasad Nellitheertha <hari@in.ibm.com> This patch contains the code that provides an ELF format interface to the previous kernel's memory post kexec reboot.
