From c7445d8c8eb34ca97cd2a28cc9d874df40d94557 Mon Sep 17 00:00:00 2001 From: Shannon Zhao Date: Thu, 7 Apr 2016 14:28:14 +0800 Subject: [PATCH] xen/arm: map_dev_mmio_region: printk should be ratelimited The function map_dev_mmio_region is used in a hypercall. Therefore all printks should be ratelimited to avoid a malicious guest flooding the console.
