fd4144d413 migration: to_dst_file at that point is NULL
We have just arrived as:

migration.c: qemu_migrate()
  ....
  s = migrate_init() <- puts it to NULL
  ....
  {tcp,unix}_start_outgoing_migration ->
     socket_outgoing_migration
        migration_channel_connect()
	   sets to_dst_file

if tls is enabled, we do another round through
migrate_channel_tls_connect(), but we only set it up if there is no
error.  So we don't need the assignation.  I am removing it to remove
in the follwing patches the knowledge about MigrationState in that two
files.

062d81f0e9 migration: setup bi-directional I/O channel for exec: protocol
Historically the migration data channel has only needed to be
unidirectional. Thus the 'exec:' protocol was requesting an
I/O channel with O_RDONLY on incoming side, and O_WRONLY on
the outgoing side.

This is fine for classic migration, but if you then try to run
TLS over it, this fails because the TLS handshake requires a
bi-directional channel.

0bed71edbc slirp: allow host port 0 for hostfwd
The OS will allocate automatically a free port. This is useful if you
want to be sure to not get any port conflict. You still have to figure
out which port you got, for example with "lsof" (this could be exposed
in the monitor if needed).

Example of use:

     $ qemu-system-x86_64 -net user,hostfwd=127.0.0.1:0-:22 ...

Then, get your port with:

     $ lsof -np 1474 | grep LISTEN

After triggering a freeze command without any following thaw command,
qemu-ga will not respond to stop operation. This behaviour is wanted on Linux
as there is no time limit for a freeze command and we want to prevent
quitting in the middle of freeze, on the other hand on Windows the time
limit for freeze is 10 seconds, so we should wait for the timeout, thaw
the file system and quit.

               is always filled in by the guest agent when the structure
               is returned, and always ignored on input (hence it can be

Currently 'can-offline' is missing entirely from the reply. This causes
errors in libvirt which is expecting the reply to be compliant with the
schema docs.

f342cc93ec qemu-ga: Make QGA VSS provider service run only when needed
Currently the service runs in background on boot even though it is not
needed and once it is running it never stops. The service needs to be
running only during freeze operation and it should be stopped after
executing thaw.

the output.  Even though this code is dead, it gets translated, and
without the initialization we encounter a tcg_error.

This reverts commit 0fc8aec7de.

In commit 2dfe5113b1 we split a trace event with a lot of arguments
in two, because the UST trace backend has a limit on the number
of arguments you can have in a single trace event. Unfortunately
we subsequently forgot about this, and in commit 0fc8aec7de
we merged the two trace events again, recreating the "UST backend
doesn't build" bug.

 Highlights are:

     * Substantial improvement to the 'powernv' machine type
         - Includes an MMIO XICS version
     * POWER9 support improvements
         - POWER9 guests with KVM
         - Partial support for POWER9 guests with TCG
     * IOMMU and VFIO improvements
     * Assorted minor changes
 
 There are several IPMI patches here that aren't usually in my area of
 maintenance, but there isn't a regular maintainer and these patches
 are for the benefit of the powernv machine type.
 
 This pull request supersedes my 2017-04-26 pull request.  This new set

b1c897d587 e500,book3s: mfspr 259: Register mapped/aliased SPRG3 user read
This patch registers mfspr 259 for Book3S and e500 family cores
following this research:

mfspr 259 provides read-only mapped user access to SPRG3(SPR 275) according to:

- PowerISA 2.02, Book III (documents implementation starting with POWER4+ @ p20)
- IBM PowerPC 970MP RISC Microprocessor User's Manual v2.1, page 48
- Amit Singh: "Mac OS X Internals: A Systems Approach" on 970 and 970FX cores:
  He demonstrates mfspr 259 reading TLS data from Mac OS X on G5 on page 588
- NXP documents it in the Core Reference Manuals of: e500, e500mc and e5500
- getcpu() of the 32 & 64-bit Book3S Linux vDSOs use it to read the core number

mfspr 259 does not appear to be implemented in these cores according to:

- 74xx series: MPC7410/MPC7400 and MPC7450 RISC Microprocessor Reference Manuals
- 4xx series:  PPC440 Processor User's Manual, Revision 1.09 by AMCC
- 750 series:  IBM PowerPC 750CL RISC Microprocessor User's Manual
- e200 series: e200z4 Power Architectureâ Core Reference Manual

Implementation: gen_spr_usprg3() is called from init_proc_book3s_common()
(covers the 970 and POWER cores) and init_proc_e500() (covers the e500 family)
to register spr_read_ureg() in the same way which it already provides
the mapped SPR access for SPR_USPRG4-7 in gen_spr_usprgh() for cores
which have the same read-only mapped SPRG register access for SPRG4-7.

Verified using Linux by pinning a thread to a core and checking sched_getcpu()
using qemu-system-ppc64 -M pseries -cpu POWER8 using MTTCG on a x86_64 host.

31b2b0f846 target/ppc: Flush TLB on write to PIDR
The PIDR (process id register) is used to store the id of the currently
running process, which is used to select the process table entry used to
perform address translation. This means that when we write to this register
all the translations in the TLB become outdated as they are for a
previously running process. Thus when this register is written to we need
to invalidate the TLB entries to ensure stale entries aren't used to
to perform translation for the new process, which would result in at best
segfaults or alternatively just random memory being accessed.

aeaef83dab ppc/pnv: add initial IPMI sensors for the BMC simulator
Skiboot, the firmware for the PowerNV platform, expects the BMC to
provide some specific IPMI sensors. These sensors are exposed in the
device tree and their values are updated by the firmware at boot time.

Sensors of interest are :

	"FW Boot Progress"
	"Boot Count"

As such a device is defined on the command line, we can only detect
its presence at reset time.

04f6c8b2c0 ppc/pnv: populate device tree for IPMI BT devices
When an ipmi-bt device [1] is defined on the ISA bus, we need to
populate the device tree with the object properties. Such devices are
created with the command line options :

   -device ipmi-bmc-sim,id=bmc0 -device isa-ipmi-bt,bmc=bmc0,irq=10
