-From e698f4ab05a710e4463317ea978d426d43107e27 Mon Sep 17 00:00:00 2001
-From: Julien Grall <julien.grall@linaro.org>

-Subject: [PATCH 1/2] xen/arm: vgic-v3: message in the emulation code should be
- rate-limited
-
-printk by default is not rate-limited by default. Therefore a malicious guest
-may be able to flood the Xen console.
-
-If we use gdprintk, unnecessary information will be printed such as the
-filename and the line. Instead use XENLOG_G_{ERR,DEBUG} combine with %pv.
-
-Also remove the vGICv3 prefix which is not neccessary and update some
-message which were wrong.
-
