Subject: [PATCH] arm64/ptdump:display the Linear Mapping start marker
From: Hailong Liu <liu.hailong6@....com.cn>
The current /sys/kernel/debug/kernel_page_tables does not display the
*Linear Mapping start* marker on arm64, which I think should be paired
with the *Linear Mapping start* marker.
Since *Linear Mapping start* is the first marker, use level=-1 to display it.
