Subject: ARM: 8030/1: ARM : kdump : add arch_crash_save_vmcoreinfo

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.
