It does not make much sense to use a backing image for the target when
you concatenate multiple images (because then there is no correspondence
between the source images' backing files and the target's); but it was
still possible to give one by using -o backing_file=X instead of -B X.
Fix this by moving the check.
(Also, change the error message because -B is not the only way to
specify the backing file, evidently.)

After storing the creation options for the new image into @opts, we
fetch some things for our own information, like the backing file name,
or whether to use encryption or preallocation.
With the -n parameter, there will not be any creation options; this is
not too bad because this just means that querying a NULL @opts will
always return the default value.
However, we also use @opts for the --object options. Therefore, @opts is
not necessarily NULL if -n was specified; instead, it may contain those
options. In practice, this probably does not cause any problems because
there most likely is no object that supports any of the parameters we
query here, but this is neither something we should rely on nor does
this variable reuse make the code very nice to read.
Therefore, just use a separate variable for the --object options.

tail_padding_bytes is calculated wrong. F.e. for

bytes = 2048
align = 512
we will have tail_padding_bytes = 512 which is definitely wrong. The patch
fixes that arithmetics.
Fortunately this problem is harmless, we will have 1 extra allocation and
free thus there is no need to put this into stable. The problem is here
from the very beginning.

The block layer takes care of removing the bs->file child if the block
driver's bdrv_open()/bdrv_file_open() implementation fails. The block
driver therefore does not need to do so, and indeed should not unless it
sets bs->file to NULL afterwards -- because if this is not done, the
bdrv_unref_child() in bdrv_open_inherit() will dereference the freed
memory block at bs->file afterwards, which is not good.
We can now decide whether to add a "bs->file = NULL;" after each of the
offending bdrv_unref_child() invocations, or just drop them altogether.
The latter is simpler, so let's do that.

Mirror calculates job len from current I/O progress:
s->common.len = s->common.offset +
(cnt + s->sectors_in_flight) * BDRV_SECTOR_SIZE;
The final "len" of a failed mirror job in iotests 109 depends on the
subtle timing of the completion of read and write issued in the first
mirror iteration. The second iteration may or may not have run when the
I/O error happens, resulting in non-deterministic output of the
BLOCK_JOB_COMPLETED event text.

* Substantial improvement to the 'powernv' machine type
- Includes an MMIO XICS version
* POWER9 support improvements

* Assorted minor changes

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.

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.

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.

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

The default LPC bus of a multichip system is on chip 0. It's
recognized by the firmware (skiboot) using a "primary" property in the
device tree.
We introduce a pnv_chip_lpc_offset() routine to locate the LPC node of
a chip and set the property directly from the machine level.

xics_system_init() does not need 'nr_servers' anymore as it is only
used to define the 'interrupt-controller' node in the device tree. So
let's just compute the value when calling spapr_dt_xics().
This also gives us an opportunity to simplify the xics_system_init()
routine and introduce a specific spapr_ics_create() helper to create
the sPAPR ICS object.

This patch exposes a new IPMI routine to query a sdr entry from the
sdr table maintained by the IPMI BMC simulator. The API is very
similar to the internal sdr_find_entry() routine and should be used
the same way to query one or all sdrs.
A typical use would be to loop on the sdrs to build nodes of a device
tree.

This patch provides a simple FRU support for the BMC simulator. FRUs
are loaded from a file which name is specified in the object
properties, each entry having a fixed size, also specified in the
properties. If the file is unknown or not accessible for some reason,
a unique entry of 1024 bytes is created as a default. Just enough to
start some simulation.
These commands complies with the IPMI spec : "34. FRU Inventory Device
Commands".
