[PATCH 0/4] Makedumpfile: Add 5-level paging support

[Baoquan He]

Kernel has 5-level paging support and now can support boot-time
switching between 4/5-level paging mode. This patchset is used to add
5-level paging support in makedumpfile.

A kernel fix is posted to export 'pgtable_l5_enabled' to tell if
the corrupted kernel is in 5-level paging mode.
https://patchwork.kernel.org/patch/10253399/

Patch 0001 and 0004 were made by Dou Liyang. While it doesn't work on
the latest 5-level code. So add patch 0002 to introduce 'pgtable_l5_enabled'.
Change and take out the function check_5level_paging() from dou's old
patch and add it into patch 0003. Except of these, don't touch other
part of dou's patches.

Thanks, dou, for the effort!
