From 4473b570a7ebb502f63f292ccfba7df622e5fdd3 Mon Sep 17 00:00:00 2001 From: Wanpeng Li Date: Mon, 18 Aug 2014 17:50:28 +0800 Subject: [PATCH] KVM: x86: drop fpu_activate hook The only user of the fpu_activate hook was dropped in commit 2d04a05bd7e9 (KVM: x86 emulator: emulate CLTS internally, 2011-04-20). vmx_fpu_activate and svm_fpu_activate are still called on #NM (and for Intel CLTS), but never from common code; hence, there's no need for a hook.
