------------------
From: Liu Hua <sdu.liu@huawei.com>
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.
