Roman Kagan bda055096b i386: expose floppy drive CMOS type
Make it possible to query the CMOS type of a floppy drive outside of the
source file where it's defined.

It will allow to properly populate the corresponding ACPI objects and
thus enable Windows on BIOS-less systems to access the floppy drives.

Roman Kagan 9b613f4e40 i386/acpi: make floppy controller object dynamic
Instead of statically declaring the floppy controller in DSDT, with its
_STA method depending on some obscure bit in the parent ISA bridge, add
the object dynamically to DSDT via AML API only when the controller is
present.

The _STA method is no longer necessary and is therefore dropped.  So are
the declarations of the fields indicating whether the contoller is
enabled.

Igor Mammedov c9f4b77ad5 pc-dimm: fix error handling in pc_dimm_check_memdev_is_busy()
If host_memory_backend_get_memory() were to return error and
NULL MemoryRegion, pc_dimm_check_memdev_is_busy() would crash
dereferencing NULL pointer in memory_region_is_mapped().
But if error is set and non NULL MemoryRegion is returned
then error_setg() will fail with "error already set" assertion
in error_setv()

To avoid above issues use typical error handling pattern
for property setters:

Error *local_error = NULL;
...
error_propagate(errp, local_err);

Ladi Prosek 4eae2a657d balloon: fix segfault and harden the stats queue
The segfault here is triggered by the driver notifying the stats queue
twice after adding a buffer to it. This effectively resets stats_vq_elem
back to NULL and QEMU crashes on the next stats timer tick in
balloon_stats_poll_cb.

This is a regression introduced in 51b19ebe43, although admittedly
the device assumed too much about the stats queue protocol even before
that commit. This commit adds a few more checks and ensures that the one
stats buffer gets deallocated on device reset.

This is a very limited form of support for runtime patching -
similar in functionality to what we can do with ACPI_EXTRACT
macros in python, but implemented in C.

This is to allow ACPI code direct access to data tables -
which is exactly what DataTableRegion is there for, except
no known windows release so far implements DataTableRegion.

Liang Li 28b90d9c19 cutils: add avx2 instruction optimization
buffer_find_nonzero_offset() is a hot function during live migration.
Now it use SSE2 instructions for optimization. For platform supports
AVX2 instructions, use AVX2 instructions for optimization can help
to improve the performance of buffer_find_nonzero_offset() about 30%
comparing to SSE2.

Live migration can be faster with this optimization, the test result
shows that for an 8GiB RAM idle guest just boots, this patch can help
to shorten the total live migration time about 6%.

This patch use the ifunc mechanism to select the proper function when
running, for platform supports AVX2, execute the AVX2 instructions,
else, execute the original instructions.

Gerd Hoffmann e0d2bd5195 input: linux evdev support
This patch adds support for reading input events directly from linux
evdev devices and forward them to the guest.  Unlike virtio-input-host
which simply passes on all events to the guest without looking at them
this will interpret the events and feed them into the qemu input
subsystem.

Therefore this is limited to what the qemu input subsystem and the
emulated input devices are able to handle.  Also there is no support for
absolute coordinates (tablet/touchscreen).  So we are talking here about
basic mouse and keyboard support.

The advantage is that it'll work without virtio-input drivers in the
guest, the events are delivered to the usual ps/2 or usb input devices
(depending on what the machine happens to have).  And for keyboards
qemu is able to switch the keyboard between guest and host on hotkey.
The hotkey is hard-coded for now (both control keys), initialy the
guest owns the keyboard.

Probably most useful when assigning vga devices with vfio and using a
physical monitor instead of vnc/spice/gtk as guest display.

Usage:  Add '-input-linux /dev/input/event<nr>' to the qemu command
line.  Note that udev has rules which populate /dev/input/by-{id,path}
with static names, which might be more convinient to use.

Add a fw_cfg device node to the ACPI DSDT. While the guest-side
firmware can't utilize this information (since it has to access
the hard-coded fw_cfg device to extract ACPI tables to begin with),
having fw_cfg listed in ACPI will help the guest kernel keep a more
accurate inventory of in-use IO port regions.

 -object filter-buffer,id=f1,netdev=un0

This is because we don't check whether or not the filter was in the
