* commit '6c779f22':
  Change ram_save_block to return -1 if there are no more changes
  ram: save_live_setup() we don't need to synchronize the dirty bitmap.
  ram: iterate phase
  ram: save_live_complete() only do one loop
  ram: save_live_setup() don't need to sent pages
  savevm: split save_live into stage2 and stage3
  savevm: split save_live_setup from save_live_state
  savevm: introduce is_active method
  savevm: Refactor cancel operation in its own operation
  savevm: remove SaveLiveStateHandler
  savevm: remove SaveSetParamsHandler
  savevm: Live migration handlers register the struct directly
  savevm: Use a struct to pass all handlers

According to the Intel manual
"Intel® 64 and IA-32 Architectures Software Developer’s Manual
Volume 3", "3.4.4 Segment Loading Instructions in IA-32e Mode":

"When in compatibility mode, FS and GS overrides operate as defined by
32-bit mode behavior regardless of the value loaded into the upper 32
linear-address bits of the hidden descriptor register base field.
Compatibility mode ignores the upper 32 bits when calculating an effective address."

However, the code misses the 64-bit mode case, where an instruction with
address and segment size override would be translated incorrectly. For example,
inc dword ptr gs:260h[ebx*4] gets incorrectly translated to:

(uint32_t)(gs.base + ebx * 4 + 0x260)
instead of
gs.base + (uint32_t)(ebx * 4 + 0x260)

This patch will fix the following linking failed:

  LINK  qemu-ga
gcc: error: qga/../qapi-generated/qga-qapi-types.o: No such file or directory
gcc: error: qga/../qapi-generated/qga-qapi-visit.o: No such file or directory
gcc: error: qga/../qapi-generated/qga-qmp-marshal.o: No such file or directory
make: *** [qemu-ga] Error 1

Commit cdc976b0 changes the
dependencies of qemu-ga to depend "../qapi-generated/qga-qapi-types.o",
which will be expanded to "qga/../qapi-generated/qga-qapi-types.o" when
building qemu-ga.

In top-level Makefile, we defined a target "qapi-generated/qga-qapi-types.o"
which was not equal to "qga/../qapi-generated/qga-qapi-types" in the
Makefile world. So "No such file" error happened when qemu-ga was linking.

The easy approach to fix is to change the target name to
"qga/../qapi-generated/qga-qapi-types.o", but it is weird.

So, in order to solve it more graciously, I move those temporary
files(qga-qapi-*.{c,h}) qemu-ga depends on to qemu-ga/qapi-generated,
this makes dependencies more clearer.

The qemu_chr_new() function doesn't set errno on failure, so
don't print strerror(errno) on the error handling path when
dealing with the -serial, -parallel and -virtioconsole arguments.
This avoids nonsensical error messages like:
  $ ./arm-softmmu/qemu-system-arm -serial wombat
  qemu: could not open serial device 'wombat': Success

We also rephrase the message slightly to make it a little clearer
that we're expecting the name of a QEMU chr backend rather than
a host or guest serial/parallel/etc device.

Quote from ISA, 2.1:

For most Xtensa instructions, bit numbering is irrelevant; only the BBC
and BBS instructions assign bit numbers to values on which the processor
operates. The BBC/BBS instructions use big-endian bit ordering (0 is the
most-significant bit) on a big-endian processor configuration.

I "reverse engineered" the following permissions between the -socket
sub-options:

             fd  listen  connect  mcast  udp | localaddr
  fd         x   .       .        .      .   | .
  listen     .   x       .        .      .   | .
  connect    .   .       x        .      .   | .
  mcast      .   .       .        x      .   | x
  udp        .   .       .        .      x   | x
  -------------------------------------------+
  localaddr  .   .       .        x      x     x

I transformed the code accordingly. The real fix would be to embed "fd",
"listen", "connect", "mcast" and "udp" in a separate union. However
OptsVisitor's enum parser only supports the type=XXX QemuOpt instance as
union discriminator.
