From d09beabd7cd4cf70d982ff54656dc6431df80fa4 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Mon, 4 Apr 2011 12:39:25 +0200 Subject: KVM: x86 emulator: Add check_perm callback This patch adds a check_perm callback for each opcode into the instruction emulator. This will be used to do all necessary permission checks on instructions before checking whether they are intercepted or not.
