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!
