Subject: [PATCH 01/13] KVM: x86 emulator: add macros for repetitive instructions
Date: Mon, 26 Jul 2010 14:37:39 +0300 [thread overview]
Message-ID: <1280144271-328-2-git-send-email-avi@redhat.com> (raw)
In-Reply-To: <1280144271-328-1-git-send-email-avi@redhat.com>
Some instructions are repetitive in the opcode space, add macros for
consolidating them.
