In commit f0aff25570 we made cpacr_write() enforce that some CPACR
bits are RAZ/WI and some are RAO/WI for ARMv7 cores. Unfortunately
we forgot to also update the register's reset value. The effect
was that (a) a guest that read CPACR on reset would not see ones in
the RAO bits, and (b) if you did a migration before the guest did
a write to the CPACR then the migration would fail because the
destination would enforce the RAO bits and then complain that they
didn't match the zero value from the source.
Implement reset for the CPACR using a custom reset function
that just calls cpacr_write(), to avoid having to duplicate
the logic for which bits are RAO.
This bug would affect migration for TCG CPUs which are ARMv7
with VFP but without one of Neon or VFPv3.

Coverity found that the string return by 'object_get_canonical_path' was not
being freed at two locations in the model (CID 1391294 and CID 1391293) and
also that a memset was being called with a value greater than the max of a byte
on the second argument (CID 1391286). This patch corrects this by adding the
freeing of the strings and also changing to memset to zero instead on
descriptor unaligned errors.

When QEMU is started with following CLI
-machine virt,gic-version=3,accel=kvm -cpu host -bios AAVMF_CODE.fd
it crashes with abort at
accel/kvm/kvm-all.c:2164:
KVM_SET_DEVICE_ATTR failed: Group 6 attr 0x000000000000c665: Invalid argument
Which is caused by implicit dependency of kvm_arm_gicv3_reset() on
arm_gicv3_icc_reset() where the later is called by CPU reset
reset callback.
However commit:
3b77f6c arm/boot: split load_dtb() from arm_load_kernel()
broke CPU reset callback registration in case
arm_load_kernel()
...
if (!info->kernel_filename || info->firmware_loaded)
branch is taken, i.e. it's sufficient to provide a firmware
or do not provide kernel on CLI to skip cpu reset callback
registration, where before offending commit the callback
has been registered unconditionally.
Fix it by registering the callback right at the beginning of
arm_load_kernel() unconditionally instead of doing it at the end.
NOTE:
we probably should eliminate that dependency anyways as well as
separate arch CPU reset parts from arm_load_kernel() into CPU
itself, but that refactoring that I probably would have to do
anyways later for CPU hotplug to work.

Depending on the host abi, float16, aka uint16_t, values are
passed and returned either zero-extended in the host register
or with garbage at the top of the host register.
The tcg code generator has so far been assuming garbage, as that
matches the x86 abi, but this is incorrect for other host abis.
Further, target/arm has so far been assuming zero-extended results,
so that it may store the 16-bit value into a 32-bit slot with the
high 16-bits already clear.
Rectify both problems by mapping "f16" in the helper definition
to uint32_t instead of (a typedef for) uint16_t. This forces
the host compiler to assume garbage in the upper 16 bits on input
and to zero-extend the result on output.

This option allows pausing QEMU in the new RUN_STATE_PRECONFIG state,
allowing the configuration of QEMU from QMP before the machine jumps
into board initialization code of machine_run_board_init()
The intent is to allow management to query machine state and additionally
configure it using previous query results within one QEMU instance
(i.e. eliminate the need to start QEMU twice, 1st to query board specific
parameters and 2nd for actual VM start using query results for
additional parameters).
The new option complements -S option and could be used with or without
it. The difference is that -S pauses QEMU when the machine is completely
initialized with all devices wired up and ready to execute guest code
(QEMU needs only to unpause VCPUs to let guest execute its code),
while the "preconfig" option pauses QEMU early before board specific init
callback (machine_run_board_init) is executed and allows the configuration
of machine parameters which will be used by board init code.
When early introspection/configuration is done, command 'exit-preconfig'
should be used to exit RUN_STATE_PRECONFIG and transition to the next
requested state (i.e. if -S is used then QEMU will pause the second
time when board/device initialization is completed or start guest
execution if -S isn't provided on CLI)
PS:
Initially 'preconfig' is planned to be used for configuring numa
topology depending on board specified possible cpus layout.

performs the image creation.
The basic job as implemented here is all that is necessary to make image
creation asynchronous and to provide a QMP interface that can be marked
stable, but it still lacks a few features that jobs usually provide: The
job will ignore pause commands and it doesn't publish more than very
basic progress yet (total-progress is 1 and current-progress advances
from 0 to 1 when the driver callbacks returns). These features can be

MIN_REFCOUNT_CACHE_SIZE is 4 and the cluster size is guaranteed to be
at most 2MB, so the minimum refcount cache size (in bytes) is always
going to fit in a 32-bit integer.
Coverity doesn't know that, and since we're storing the result in a
uint64_t (*refcount_cache_size) it thinks that we need the 64 bits and
that we probably want to do a 64-bit multiplication to prevent the
result from being truncated.
This is a false positive in this case, but it's a fair warning.
We could do a 64-bit multiplication to get rid of it, but since we
know that a 32-bit variable is enough to store this value let's simply
reuse min_refcount_cache, make it a normal int and stop doing casts.
