From bd3f79b71de0410352ab506496a467fcb0620912 Mon Sep 17 00:00:00 2001 From: Stefano Stabellini Date: Wed, 22 Aug 2012 17:20:14 +0100 Subject: xen: Introduce xen_pfn_t for pfn and mfn types All the original Xen headers have xen_pfn_t as mfn and pfn type, however when they have been imported in Linux, xen_pfn_t has been replaced with unsigned long. That might work for x86 and ia64 but it does not for arm. Bring back xen_pfn_t and let each architecture define xen_pfn_t as they see fit.
