+Subject: [PATCH] x86/boot: Fix kdump, cleanup aborted E820_PRAM max_pfn
+ manipulation
+
+commit 917db484dc6a69969d317b3e57add4208a8d9d42 upstream.
+
+In commit:
+
+  ec776ef6bbe1 ("x86/mm: Add support for the non-standard protected e820 type")
+
+Christoph references the original patch I wrote implementing pmem support.
+The intent of the 'max_pfn' changes in that commit were to enable persistent
+memory ranges to be covered by the struct page memmap by default.
+
+However, that approach was abandoned when Christoph ported the patches [1], and
+that functionality has since been replaced by devm_memremap_pages().
+
+In the meantime, this max_pfn manipulation is confusing kdump [2] that
+assumes that everything covered by the max_pfn is "System RAM".  This
+results in kdump hanging or crashing.

+
+So fix it.
