From fb03cb6f44236f4bef62a0dda8e025ff5ca51417 Mon Sep 17 00:00:00 2001 From: Takuya Yoshikawa Date: Wed, 8 Feb 2012 12:59:10 +0900 Subject: KVM: Introduce gfn_to_index() which returns the index for a given level This patch cleans up the code and removes the "(void)level;" warning suppressor. Note that we can also use this for PT_PAGE_TABLE_LEVEL to treat every level uniformly later.
