QEMU as far as I know only reports LUN numbers using the modes that
are described in SAM4.
As such, since all LUN numbers generated by the SCSI emulation in QEMU
follow SAM4, we should set the HiSup bit in the standard INQUIRY data
to indicate such.
From SAM4:
4.6.3 LUNs overview
All LUN formats described in this standard are hierarchical in
structure even when only a single level in that hierarchy is used.
The HISUP bit shall be set to one in the standard INQUIRY data
(see SPC-4) when any LUN format described in this standard is used.
Non-hierarchical formats are outside the scope of this standard.

It's nice to have a flexible system to maintain CPU models as data, but
this is holding us from making improvements in the CPU code because it's
not using the common infra-structure, and because the machine-type data
is still inside C code.
Users who want to configure CPU features directly may simply use the
"-cpu" command-line option (and maybe an equivalent -device option in
the future) to set CPU features.

Commit c8057f95 (accidentally) disabled the ability to pass
option strings starting with '?' to the target-specific
cpu_list function, so the target-i386 specific "-cpu ?dump",
"-cpu ?cpuid" and "-cpu ?model" stopped working.
Since these options are undocumented and not used by libvirt,
simply drop them completely rather than reinstating them
with new style syntax. Instead, we fold the ?model and ?cpuid
output into the output of the plain "-cpu help" output. The
detailed output produced by ?dump is dropped.

Commit e31b0a7c05 fixed copy propagation on
32-bit host by restricting the copy between different types. This was the
wrong fix.
The real problem is that the all temps states should be reset at the end
of a basic block. This was done by adding such operations in the switch,
but brcond2 was forgotten (that's why the crash was only observed on 32-bit
hosts).
Fix that by looking at the TCG_OPF_BB_END instead. We need to keep the case
for op_set_label as temps might be modified through another path.

Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Because nbd_client_close removes the I/O handlers for the client
socket, there is no way that any suspended coroutines are restarted.
This will be a problem with the QEMU embedded NBD server, because
we will have a QMP command to forcibly close all connections with
the clients.
Instead, we can exploit the reference counting of NBDClients; shutdown the
client socket, which will make it readable and writeable. Also call the
close callback, which will release the user's reference. The coroutines
then will fail and exit cleanly, and release all remaining references,
until the last refcount finally triggers the closure of the client.
