From db3fe4eb45f3555d91a7124e18cf3a2f2a30eb90 Mon Sep 17 00:00:00 2001 From: Takuya Yoshikawa Date: Wed, 8 Feb 2012 13:02:18 +0900 Subject: KVM: Introduce kvm_memory_slot::arch and move lpage_info into it Some members of kvm_memory_slot are not used by every architecture. This patch is the first step to make this difference clear by introducing kvm_memory_slot::arch; lpage_info is moved into it.
