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