After commit 767adce2, they are redundant.  This way we don't assign them
except when needed.  Once there, there were lots of cases where the ".fields"
indentation was wrong:

     .fields = (VMStateField []) {
and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

The biggest problem (apart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

Commit e586822a broke the bsd-user build when it removed the
CONFIG_UNAME_RELEASE define but forgot to remove the use of it
in bsd-user. Fix this in the simplest possible way (bsd-user
doesn't make any use at all of the qemu_uname_release variable
except to allow it to be pointlessly set by the user, so this
is all we need to do.)

There was some modulo logic to ensure that Microblaze always booted into
physical RAM regardless of the elf entry. Removed it, as QEMU should fail
gracefully when given a bad elf, rather than attempt to run it.

The TCSR register has only 11 valid bits. This is now used by the

The INDEX_op_call case has just been obsoleted; the mov and movi
cases have not been reachable for years.  Attempt to document this
both in each tcg_out_op switch, and via TCG_OPF_NOT_PRESENT.

Because of the TCG_OPF_NOT_PRESENT change, this must be done for
all targets in a single commit.

Avoid allocating a tcg temporary to hold the constant address,
and instead place it directly into the op_call arguments.

At the same time, convert to the newly introduced tcg_out_call
backend function, rather than invoking tcg_out_op for the call.

Using a 16-byte aligned structure achieves best results, both for code
cleanliness and compiled code size.  However, this means that we can't
use the trick of encoding the slot number into the low 2 bits.

Thankfully, we only ever use slot2, so make that explicit in the names
of the relocation functions, and drop the code for other slots.

Avoid stores to unaligned addresses in TCG code generation, by using the

The code which patches x86 jump instructions assumes it can do an
unaligned write of a uint32_t. This is actually safe on x86, but it's
still undefined behaviour. We have infrastructure for doing efficient
unaligned accesses which doesn't engage in undefined behaviour, so
use it.

This is technically fractionally less efficient, at least with gcc 4.6;
instead of one instruction:
 7b2:   89 3e                   mov    %edi,(%rsi)
we get an extra spurious store to the stack slot:
 7b2:   89 7c 24 64             mov    %edi,0x64(%rsp)
 7b6:   89 3e                   mov    %edi,(%rsi)

Currently all what's needed for single file libcacard/vcard_emul_nss.c
(libnss cflags) and hw/usb/ccid-card-emulated.c (libcacard includes)
together with the libs is added to global QEMU_CFLAGS and libs_softmmu.

Use the cflags only where really used (for two mentioned files), and
libs only where needed.

While at it, rename variables to better reflect reality: libcacard_*
is really nss_*.

This needs a bit more tweaking: $(NSS_LIBS) should not contain $glib_libs
(ditto for _cflags).  But in order to fix it, some more preparations
should be made first.  So add a FIXME comment.

fix-obj-vars has the undesired side effect of breaking -cflags
-objs and -libs variables in the toplevel Makefile.objs.  The
variables in the toplevel Makefile.objs do not need any fix,
so fix-obj-vars need not do anything.

Since we are touching it, remove the now unnecessary $(if)

g_poll has a problem on Windows when using
timeouts < 10ms, in glib/gpoll.c:

/* If not, and we have a significant timeout, poll again with
 * timeout then. Note that this will return indication for only
 * one event, or only for messages. We ignore timeouts less than
 * ten milliseconds as they are mostly pointless on Windows, the
 * MsgWaitForMultipleObjectsEx() call will timeout right away
 * anyway.
 */
if (retval == 0 && (timeout == INFINITE || timeout >= 10))
  retval = poll_rest (poll_msgs, handles, nhandles, fds, nfds, timeout);

so whenever g_poll is called with timeout < 10ms it does
a quick poll instead of wait, this causes significant performance
degradation of QEMU, thus we should use WaitForMultipleObjectsEx
directly
