+From: Petr Tesarik <ptesarik@suse.cz>
+Date: Thu, 24 Apr 2014 10:58:43 +0900
+Subject: [PATCH] [PATCH v3] Introduce the mdf_pfn_t type.
+
+Replace unsigned long long with mdf_pfn_t where:
+
+  a. the variable denotes a PFN
+  b. the variable is a number of pages
+
+The number of pages is converted to a mdf_pfn_t, because it is a result
+of subtracting two PFNs or incremented in a loop over a range of PFNs,
+so it can get as large as a PFN.
+
+Note: The mdf_ (i.e. makedumpfile) prefix is used to prevent possible
+conflicts with other software that defines a pfn_t type.
