Subject: [Qemu-devel] [PATCH 01/15] exec: remove obsolete comment
Date: Fri, 24 May 2013 19:02:53 +0200	[thread overview]
Message-ID: <1369414987-8839-2-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1369414987-8839-1-git-send-email-pbonzini@redhat.com>

See how we call memory_region_section_addr two lines below to
convert a physical address to a base address in the region.
