At least 2 acked patches were not committed to qemu-traditional before
the RC1 freeze & tag.

The above patch (against qemu-traditional - qemu-upstream is OK) was
acked a couple of days before Friday's RC1 code freeze, but it still
remains uncommitted.  This patch appears to be needed to build
successfully on Ubuntu Server 13.04, as I was unable to build
yesterday's xen-unstable (specifically the qemu-traditional portion)
without the above patch.

Another patch (subject line "Re: [PATCH] qemu-traditional: do not
strip binaries during make install") was also acked on May 1, but
remains uncommitted.
