+Subject: [PATCH] sadump: fix failure of reading memory when 5-level
+ paging is enabled
+
+makedumpfile fails as follows for memory dumps collected by sadump
+when 5-level paging is enabled on the corresponding systems:
+
+    # makedumpfile -l -d 31 -x ./vmlinux ./dump.sadump dump.sadump-ld31
+    __vtop4_x86_64: Can't get a valid pgd.
+    ...snip...
+    __vtop4_x86_64: Can't get a valid pgd.
+    calc_kaslr_offset: failed to calculate kaslr_offset and phys_base; default to 0
+    __vtop4_x86_64: Can't get a valid pgd.
+    readmem: Can't convert a virtual address(ffffffff82fce960) to physical address.
+    readmem: type_addr: 0, addr:ffffffff82fce960, size:1024
+    cpu_online_mask_init: Can't read cpu_online_mask memory.
+
+    makedumpfile Failed.
+
+This is because 5-level paging support has not been done yet for
+sadump; the work of the 5-level paging support was done by the commit
+30a3214a7193e94c551c0cebda5918a72a35c589 (PATCH 4/4 arch/x86_64: Add
+5-level paging support) but that was focused on the core part only.
+
+Having said that, most of things has already been finished in the
+commit. What needs to be newly added for sadump is just how to check
+if 5-level paging is enabled for a given memory dump.
+
+For that purpose, let's refer to CR4.LA57, bit 12 of CR4, representing
+whether 5-level paging is enabled or not. We can do this because
+memory dumps collected by sadump have SMRAM as note information and
+they include CR4 together with the other control registers.
