From d18e173a07a9c1e7f087384a8832d295043136bb Mon Sep 17 00:00:00 2001 From: Wei Liu Date: Mon, 14 Oct 2013 13:53:53 +0100 Subject: [PATCH 1/2] xen: fix two errors when debug is enabled This patch fixes: 1. build error in xen_pt.c when XEN_PT_LOGGING_ENABLED is defined 2. debug output format string error when DEBUG_XEN is defined In the second case I also have the output info in consistent with the output in mapping function - that is, print start_addr instead of phys_offset.

As such, the device should not have a default device ID, it should always be supplied by the Xen toolstack.
