Subject: [Qemu-devel] [PATCH 09/11] exec: move qemu_ram_addr_from_host_nofail to cputlb.c
Date: Tue, 25 Jun 2013 13:13:25 +0200	[thread overview]
Message-ID: <1372158807-19715-10-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1372158807-19715-1-git-send-email-pbonzini@redhat.com>

After the next patch it would not be used elsewhere anyway.  Also,
the _nofail and the standard versions of this function return different
things, which is confusing.  Removing the function from the public headers
limits the confusion.
