vfio/migration: Add support for switchover ack capability
Loading of a VFIO device's data can take a substantial amount of time as
the device may need to allocate resources, prepare internal data
structures, etc. This can increase migration downtime, especially for
VFIO devices with a lot of resources.
To solve this, VFIO migration uAPI defines "initial bytes" as part of
its precopy data stream. Initial bytes can be used in various ways to
improve VFIO migration performance. For example, it can be used to
transfer device metadata to pre-allocate resources in the destination.
However, for this to work we need to make sure that all initial bytes
are sent and loaded in the destination before the source VM is stopped.
Use migration switchover ack capability to make sure a VFIO device's
initial bytes are sent and loaded in the destination before the source
stops the VM and attempts to complete the migration.
This can significantly reduce migration downtime for some devices.

migration: Add switchover ack capability
Migration downtime estimation is calculated based on bandwidth and
remaining migration data. This assumes that loading of migration data in
the destination takes a negligible amount of time and that downtime
depends only on network speed.
While this may be true for RAM, it's not necessarily true for other
migrated devices. For example, loading the data of a VFIO device in the
destination might require from the device to allocate resources, prepare
internal data structures and so on. These operations can take a
significant amount of time which can increase migration downtime.
This patch adds a new capability "switchover ack" that prevents the
source from stopping the VM and completing the migration until an ACK
is received from the destination that it's OK to do so.
This can be used by migrated devices in various ways to reduce downtime.
For example, a device can send initial precopy metadata to pre-allocate
resources in the destination and use this capability to make sure that
the pre-allocation is completed before the source VM is stopped, so it
will have full effect.
This new capability relies on the return path capability to communicate
from the destination back to the source.
The actual implementation of the capability will be added in the
following patches.

target/i386: emulate 64-bit ring 0 for linux-user if LM feature is set
32-bit binaries can run on a long mode processor even if the kernel
is 64-bit, of course, and this can have slightly different behavior;
for example, SYSCALL is allowed on Intel processors.
Allow reporting LM to programs running under user mode emulation,
so that "-cpu" can be used with named CPU models even for qemu-i386
and even without disabling LM by hand.
Fortunately, most of the runtime code in QEMU has to depend on HF_LMA_MASK
or on HF_CS64_MASK (which is anyway false for qemu-i386's 32-bit code
segment) rather than TARGET_X86_64, therefore all that is needed is an
update of linux-user's ring 0 setup.

XSAVES would be similar, but it doesn't make sense to provide it until
XSAVEC is implemented.
With this change, all CPUs up to Broadwell-v4 can be emulate. Skylake-Client
requires XSAVEC, while EPYC also requires SHA-NI, MISALIGNSSE and TOPOEXT.
MISALIGNSSE is not hard to implement, but I am not sure it is worth using

target/i386/WHPX: Fix error message when fail to set ProcessorCount
003f230e37d7 ("machine: Tweak the order of topology members in struct
CpuTopology") changes the meaning of MachineState.smp.cores from "the
number of cores in one package" to "the number of cores in one die"
and doesn't fix other uses of MachineState.smp.cores. And because of
the introduction of cluster, now smp.cores just means "the number of
cores in one cluster". This clearly does not fit the semantics here.
And before this error message, WHvSetPartitionProperty() is called to
set prop.ProcessorCount.
So the error message should show the prop.ProcessorCount other than
"cores per cluster" or "cores per package".

and uses that value to select keyboard layout. Also the SUN bios like the one
in the file ss5.bin uses this value to support at least some keyboard layouts.
However, the OpenBIOS provided with qemu is hardcoded to always use an US
keyboard layout.
Before this patch, qemu allways gave dip switch value 0x21 (US keyboard),
this patch uses a command line switch like
"-global escc.chnA-sunkbd-layout=de" to select dip switch value. A table is
used to lookup values from arguments like:
-global escc.chnA-sunkbd-layout=fr
-global escc.chnA-sunkbd-layout=es
But the patch also accepts numeric dip switch values directly:
-global escc.chnA-sunkbd-layout=0x2b
-global escc.chnA-sunkbd-layout=43
Both values above are the same and select swedish keyboard as explained in
table 3-15 at
https://docs.oracle.com/cd/E19683-01/806-6642/new-43/index.html
Unless you want to do a full Solaris installation but happen to have
access to a Sun bios file, the easiest way to test that the patch works
is to:
qemu-system-sparc -global escc.chnA-sunkbd-layout=sv -bios /path/to/ss5.bin
If you already happen to have a Solaris installation in a qemu disk image
file you can easily try different keyboard layouts after this patch is
applied.

We incorporate %asi into tb->flags so that we may generate

Setting %asi is common for e.g. memcpy and memset performing

The function can move the child node to a different AioContext. In this
case, it also must take the AioContext lock for the new context before

iotests: Test active commit with iothread and background I/O
This is a better regression test for the bugs hidden by commit
80fc5d26
('graph-lock: Disable locking for now'). With that commit reverted, it
hangs instantaneously and reliably for me.
It is important to have a reliable test like this, because the following
commits will set out to fix the actual root cause of the deadlocks and
then finally revert commit
80fc5d26, which was only a stopgap solution.
