Raw Blame History

From 9dc6440c63320066bc6344c6e3ca3c3af88bcc42 Mon Sep 17 00:00:00 2001
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.
