From 828554136bbacae6e39fc31b9cd7e7c660ad7530 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Thu, 1 Jul 2010 16:00:11 +0200 Subject: KVM: Remove unnecessary divide operations This patch converts unnecessary divide and modulo operations in the KVM large page related code into logical operations. This allows to convert gfn_t to u64 while not breaking 32 bit builds.
