[Juan Quintela <quintela@redhat.com>]

The following changes since commit 932eacc158c064935c7bab920c88a93a629e1ca4:

  Merge branch 'xtensa' of git://jcmvbkbc.spb.ru/dumb/qemu-xtensa (2011-11-02 20:52:23 +0000)

are available in the git repository at:

  git://repo.or.cz/qemu/quintela.git vmstate-cpus-for-anthony

[v3]
- rebase to top
- fix sparc/arm/i386 changes in upstream
- all reviews were positive, Anthony, please pull

[v2] Changes since v1

- preserve arm comment that was missing (pbrook)
- add copyright notice to the files that were empty
- new patches:
  * fix formating for i386
  * remove unneeded includes
  * rename machine.c to vmstate.c

Later, Juan.

[v1]

This series port all cpus to use vmstate.
- 1st patch is a fix of vmstate.
- I discussed the arm changes over irc with Peter, he agreed that some
  simplification could be good, but he didn't saw the patches O:-)
- mips: no pci chipset has been ported, so migration don't work there.
  I have embedded a couple of structs to improve vmstate checking.  Notice
  that they were always allocated, so there shouldn't be any problem.
- sparc: I changed the format a little bit to be able to use normal arrays.
- sparc: If we always send the whole register windows, we don't need
  VMSTATE_VARRAY_MULTIPLY.  As that array is quite big (520 elements), I am not
  sure what is best.
- cpsr_vmstate on arm: I am not sure if I could "abuse" uncached_cpsr for that
  purpose?

I have only tested on x86, for the rest, I double checked, but it is
possible that I missed something.  I expect all patches to be
integrated by Anthony in one go.  Architecture maintainers are CC'd
for an ACK/NACK/comments.

Please, review.

PD. Is there an easy way of creating this "CC" list of mail addresses,
    or the only way is to edit comments and write it by hand as I did?
