From: Liu Hua <[email protected]> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== commit 56b700fd6f1e49149880fb1b6ffee0dca5be45fb upstream. 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.
