After commit 767adce2d, 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.

Update our copy of libvixl to upstream's 1.4 release.
Note that we no longer need any local fixes for compilation
on 32 bit hosts -- they have all been integrated upstream.

Commit e586822a5 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
linux kernel to auto-detect endianness, and causes Linux 3.15-rc1
and later to hang when run under qemu-microblaze. Mask valid bits
before writing the register to solve the problem.

The MER register only has two valid bits. This is now used by

and later to hang when run under qemu-microblaze. Mask valid bits before

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.

The move opcodes are special in that their constraints must cover
all available registers. So instead of checking the constraints,
just use the available registers.

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.

To be defined by the tcg backend based on the elemental unit of the ISA.
During the transition, allow TCG_TARGET_INSN_UNIT_SIZE to be undefined,
which allows us to default tcg_insn_unit to the current uint8_t.

Avoid stores to unaligned addresses in TCG code generation, by using the
usual memcpy() approach. (Using bswap.h would drag a lot of QEMU baggage
into TCG, so it's simpler just to do direct memcpy() here.)

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)
in the callers.

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
