register_savevm(NULL, "cpu", cpu_index, CPU_SAVE_VERSION,

register_savevm(NULL, "cpu", 0, 3, cpu_save, cpu_load, env)
CPU_SAVE_VERSION is defined as 3 in target-mips/cpu.h.
fulong2e instantiates one CPU, so its cpu_index is 0.
Thus the two are fully identical.
Therefore just remove the second call in fulong2e.

Commit de024815e3 (target-i386: QOM'ify
CPU init) moved mce_init() call from helper.c:cpu_x86_init() into
X86CPU's cpu.c:x86_cpu_initfn().
mce_init() checks for a family >= 6 though, so we could end up with a
sequence such as for -cpu somecpu,family=6:
x86_cpu_initfn => X86CPU::family == 5
mce_init => no-op
cpu_x86_register => X86CPU::family = 6
=> MCE unexpectedly not init'ed
or for -cpu someothercpu,family=5:
x86_cpu_initfn => X86CPU::family == 6
mce_init => init'ed
cpu_x86_register => X86CPU::family = 5
=> MCE unexpectedly init'ed
Therefore partially revert the above commit. To avoid moving
mce_init() back into helper.c, foresightedly move it into a
new x86_cpu_realize() function and, in lack of ObjectClass::realize,
call it directly from cpu_x86_init().
While at it, move the qemu_init_vcpu() call that used to follow
mce_init() in cpu_x86_init() into the new realizefn as well.

This is a partial revert of commits a369da5 (vga: improve VGA logic,
committed 2012-01-22) and c5bd4f3 (vga: fix -nodefaults -device VGA,
2012-01-24) which broke command-line option parsing in different ways.
Since commit a369da5 it has become impossible to specify a VGA device
entirely with QemuOpts-enabled options, i.e. without needing an explicit
"-vga none".
In addition, until commit c5bd4f3 -nodefaults would not disable the device
you specified with the legacy "-vga" option, independent of the order.
Since commit c5bd4f3 QEMU -nodefaults will override a previous -vga
option.
I did not reintroduce machine->no_vga. Boards can simply ignore the
vga_interface_type variable, and most will indeed do so.

Use help functions in qemu-socket.c for tcp migration,
which already support ipv6 addresses.
Currently errp will be set to UNDEFINED_ERROR when migration fails,
qemu would output "migration failed: ...", and current user can
see a message("An undefined error has occurred") in monitor.
This patch changed tcp_start_outgoing_migration()/inet_connect()
/inet_connect_opts(), socket error would be passed back,
then current user can see a meaningful err message in monitor.
Qemu will exit if listening fails, so output socket error
to qemu stderr.
For IPv6 brackets must be mandatory if you require a port.
Referencing to RFC5952, the recommended format is:
[2312::8274]:5200
test status: Successed
listen side: qemu-kvm .... -incoming tcp:[2312::8274]:5200
client side: qemu-kvm ...
