From 56b700fd6f1e49149880fb1b6ffee0dca5be45fb Mon Sep 17 00:00:00 2001 From: Liu Hua Date: Fri, 18 Apr 2014 07:45:36 +0100 Subject: [PATCH] ARM: 8030/1: ARM : kdump : add arch_crash_save_vmcoreinfo For vmcore generated by LPAE enabled kernel, user space utility such as crash needs additional infomation to parse. So this patch add arch_crash_save_vmcoreinfo as what PAE enabled i386 linux does.
