  hmp: fix info cpus for sparc targets

On sparc targets, info cpus returns this kind of output:

| info cpus
| * CPU #0: pc=0x0000000000424d18pc=0x0000000000424d18npc=0x0000000000424d1c 
thread_id=19460

pc is printed twice, there is no space between pc, pc and npc.

With this patch, pc is not printed anymore when has_npc is set. In addition
the space is printed before pc/nip/npc/PC instead of after the colon so that
multiple prints are possible. This result on the following kind of input on
sparc targets:

| info cpus
| * CPU #0: pc=0x0000000000424d18 npc=0x0000000000424d1c thread_id=19460

  qmp: handle stop/cont in INMIGRATE state

Right now, stop followed by an incoming migration will let the
virtual machine start.  cont before an incoming migration instead
will fail.

This is bad because the actual behavior is not predictable; it is
racy with respect to the start of the incoming migration.  That's
because incoming migration is blocking, and thus will delay the
processing of stop/cont until the end of the migration.

In addition, there's nothing that really prevents the user from
typing the block device's passwords before incoming migration is
done, so returning the DeviceEncrypted error is also helpful in
the QMP case.

Both things can be fixed by just toggling the autostart variable when
stop/cont are called in INMIGRATE state.

Note that libvirt is currently working around the race by looping
if the MigrationExpected answer is returned.  After this patch, the
command will return right away without ever raising an error.

  migration: go to paused state after finishing incoming migration with -S

At the end of migration the machine has started already, and cannot be
destroyed without losing the guest's data.  Hence, prelaunch is the
wrong state.  Go to the paused state instead.  QEMU would reach that
state anyway (after running the guest for the blink of an eye) if the
"stop" command had been received after the start of migration.

  tcg/i386: remove suboptimal register shifting

Now that CONFIG_TCG_PASS_AREG0 has been removed, it's easier to get
an optimal code for the load/store functions.

First swap the two registers used in tcg_out_tlb_load() so that the
address end-up in the second register instead of the first one. Adjust
tcg_out_qemu_ld() and tcg_out_qemu_st() to respectively call
tcg_out_qemu_ld_direct() and tcg_out_qemu_st_direct() with the correct
registers. Then replace the register shifting by direct load of the
arguments.

  tcg/i386: remove ld/st third argument register constraint

On x86_64, remove the constraint on the third argument register which
is not needed:
 - For loads the helper arguments are env, addr, mem_idx. The addr
   value should not be in the two first argument registers as they are
   used in tcg_out_tlb_load().
 - For stores the helper arguments are env, addr, data, mem_idx.
   The addr and data values should not be in the two first argument
   registers as they are used in tcg_out_tlb_load(). The data value
   should also not be in the two first argument registers, but could
   be in the third argument register in which case it would be already
   loaded at the right location.

  tcg: sync output arguments on liveness request

Synchronize an output argument when requested by the liveness analysis.
This is needed so that the temp can be declared dead later.

For that, add a new op_sync_args table in which each bit tells if the
corresponding output argument needs to be synchronized with the memory.
Pass it to the tcg_reg_alloc_* functions, and honor this bit. We need to
synchronize the argument before marking it as dead, and we have to make
sure all the infos about the temp are correctly filled.

At the same time change some types from unsigned int to uint16_t when
passing op_dead_args.

  tcg: rework liveness analysis

Rework the liveness analysis by tracking temps that need to go back to
memory in addition to dead temps tracking. This allows to mark output
arguments as "need sync", and to synchronize them back to memory as soon
as they are not written anymore. This way even arguments mapping to
globals can be marked as "dead", avoiding moves to a new register when
input and outputs are aliased.

In addition it means that registers are freed as soon as temps are not
used anymore, instead of waiting for a basic block end or an op with side
effects. This reduces register spilling especially on CPUs with few
registers, and spread the mov over all the TB, increasing the
performances on in-order CPUs.

  tcg: rewrite tcg_reg_alloc_mov()

Now that the liveness analysis provides more information, rewrite
tcg_reg_alloc_mov(). This changes the behaviour about propagating
constants and memory accesses. We now take the assumption that once
a value is loaded into a register (from memory or from a constant),
it's better to keep it there than to reload it later. This assumption
is now always almost correct given that we are now sure the
corresponding temp is going to be used later (otherwise it would have
been synchronized and marked as dead already). The assumption is wrong
if one of the op after clobbers some registers including the one
of the holding the temp (this can be avoided by allocating clobbered
registers last, which is what most TCG target do), or in case of lack
of available register.

Some branch related ops are marked with TCG_OPF_SIDE_EFFECTS, some other

The call op is marked as TCG_OPF_SIDE_EFFECTS, which might be not true
as there is are specific flags (TCG_CALL_CONST and TCG_CALL_PURE) for
specifying that. On the other hand it always clobber arguments, so mark
it as such even if the call op is handled in a different code path.

  tcg: rework TCG helper flags

The current helper flags, TCG_CALL_CONST and TCG_CALL_PURE might be
confusing and doesn't provide enough granularity for some helpers (FP
helpers for example).

This patch changes them into the following helpers flags:
- TCG_CALL_NO_READ_GLOBALS means that the helper does not read globals,
  either directly or via an exception. They will not be saved to their
  canonical location before calling the helper.
- TCG_CALL_NO_WRITE_GLOBALS means that the helper does not modify any
  globals. They will only be saved to their canonical locations before
  calling helpers, but they won't be reloaded afterwise.
- TCG_CALL_NO_SIDE_EFFECTS means that the call to the function is
  removed if the return value is not used.

It provides convenience flags, to avoid helper definitions longer than
80 characters. It also provides compatibility flags, and updates the
documentation.

With normal FP, this doesn't have much affect on the generated code,

But with Loongson multimedia instructions, which are all integral and
whose helpers are in fact CONST+PURE, this greatly improves the code.

  Add USB option in machine options

When -usb option is used, global varible usb_enabled is set.
And all the plaform will create one USB controller according
to this variable. In fact, global varibles make code hard
to read.

So this patch is to remove global variable usb_enabled and
add USB option in machine options. All the plaforms will get
USB option value from machine options.

USB option of machine options will be set either by:
  * -usb
  * -machine type=pseries,usb=on

Both these ways can work now. They both set USB option in
machine options. In the future, the first way will be removed.

  pseries: Don't allow duplicate registration of hcalls or RTAS calls

Currently the pseries machine code allows a callback to be registered
for a hypercall number twice, as long as it's the same callback the second
time.  We don't test for duplicate registrations of RTAS callbacks at all
so it will effectively be last registratiojn wins.

This was originally done because it was awkward to ensure that the
registration happened exactly once, but the code has since been
restructured so that's no longer the case.

Duplicate registration of a hypercall or RTAS call could well suggest
a duplicate initialization which could cause other problems, so this patch
makes duplicate registrations a bug, to prevent the old behaviour from
hiding other bugs.

  target-ppc: Rework storage of VPA registration state

With PAPR guests, hypercalls allow registration of the Virtual Processor
Area (VPA), SLB shadow and dispatch trace log (DTL), each of which allow
for certain communication between the guest and hypervisor.  Currently, we
store the addresses of the three areas and the size of the dtl in
CPUPPCState.

The SLB shadow and DTL are variable sized, with the size being retrieved
from within the registered memory area at the hypercall time.  This size
can later be overwritten with other information, however, so we need to
save the size as of registration time.  We already do this for the DTL,
but not for the SLB shadow, so this patch fixes that.

In addition, we change the storage of the VPA information to use fixed
size integer types which will make life easier for syncing this data with
KVM, which we will need in future.

  pseries: Implement qemu initiated shutdowns using EPOW events

At present, using 'system_powerdown' from the monitor or otherwise
instructing qemu to (cleanly) shut down a pseries guest will not work,
because we did not have a method of signalling the shutdown request to the
guest.

PAPR does include a usable mechanism for this, though it is rather more
involved than the equivalent on x86.  This involves sending an EPOW
(Environmental and POwer Warning) event through the PAPR event and error
logging mechanism, which also has a number of other functions.

This patch implements just enough of the event/error logging functionality
to be able to send a shutdown event to the guest.  At least with modern
guest kernels and a userspace that is up and running, this means that
system_powerdown from the qemu monitor should now work correctly on pseries
guests.

  PPC: e500: Map PIO space into core memory region

accessible via MMIO. Do this mapping explicitly by mapping the PIO space
of our PCI bus into a memory region that lives in memory space.
