 1. Set bInterfaceProtocol to 0x00 for usb-tablet. This should be
    non-zero for boot protocol devices only, which the usb-tablet is not.
 2. Set the usb-tablet's usage to "mouse" in the report descriptor.

The boot protocol of 0x02 specifically confused OS X/macOS' HID driver
stack, causing it to generate additional bogus HID events with relative
motion in addition to the tablet's absolute coordinate events.

Absolute pointing devices with HID Report Descriptor usage of 0x01
(pointing) are treated by the macOS HID driver as analog sticks, and
absolute coordinates are not directly translated to absolute mouse
cursor positions. Changing it to 0x02 (mouse) fixes the problem, and
does not have any adverse effect in other operating systems and
windowing systems. (VMWare does the same thing.)

  iothread: enable AioContext polling by default
Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

IOThread AioContexts are likely to consist only of event sources like
virtqueue ioeventfds and LinuxAIO completion eventfds that are pollable
from userspace (without system calls).

We recently merged the AioContext polling feature but didn't enable it
by default yet.  I have gone back over the performance data on the
mailing list and picked a default polling value that gave good results.

Let's enable AioContext polling by default so users don't have another
switch they need to set manually.  If performance regressions are found
we can still disable this for the QEMU 2.9 release.

ppc patch queue 2017-02-02

This obsoletes ppc-for-2.9-20170112, which had a MacOS build bug.

This is a long overdue ppc pull request for qemu-2.9.  It's been a
long time coming due to some holidays and inconveniently timed
problems with testing.  So, there's a lot in here:

    * More POWER9 instruction implementations for TCG
    * The simpler parts of my CPU compatibility mode cleanup
        * This changes behaviour to prefer compatibility modes over
          "raW" mode for new machine type versions
    * New "40p" machine type which is essentially a modernized and
      cleaned up "prep".  The intention is that it will replace "prep"
      once it has some more testing and polish.
    * Add pseries-2.9 machine type
    * Implement H_SIGNAL_SYS_RESET hypercall
    * Consolidate the two alternate CPU init paths in pseries by
      making it always go through CPU core objects to initialize CPU
    * A number of bugfixes and cleanups
    * Stop the guest timebase when the guest is stopped under KVM.
      This makes the guest system clock also stop when paused, which
      matches the x86 behaviour.
    * Some preliminary cleanups leading towards implementation of the
      POWER9 MMU.

There are also some changes not strictly related to ppc code, but for
its benefit:

    * Limit the pxi-expander-bridge (PXB) device to x86 guests only
      (it's essentially a hack to work around historical x86
      limitations)
    * Some additions to the 128-bit math in host_utils, necessary for
      some of the new instructions.
    * Revise a number of qtests and enable them for ppc

When running with KVM on POWER, we are registering a "family" CPU
type for the host CPU that we are running on. For example, on all
POWER8-compatible hosts, we register a "POWER8" CPU type, so that
you can always start QEMU with "-cpu POWER8" there, without the
need to know whether you are running on a POWER8, POWER8E or POWER8NVL
host machine.
However, we also have a "POWER8" CPU alias in the ppc_cpu_aliases list
(that is mainly useful for TCG). This leads to two cosmetical drawbacks:
If the user runs QEMU with "-cpu ?", we always claim that POWER8 is an
"alias for POWER8_v2.0" - which is simply not true when running with
KVM on POWER. And when using the 'query-cpu-definitions' QMP call,
there are currently two entries for "POWER8", one for the alias, and
one for the additional registered type.
To solve the two problems, we should rather update the "family" alias
instead of registering a new types. We then only have one "POWER8"
CPU definition around, an alias, which also points to the right
destination.

The cp_abort instruction is used to remove the state of an in progress
copy paste sequence. POWER9 compilers add this in various places, such
as context switches which causes illegal instruction signals since we
don't yet implement this instruction.

Given there is no implementation of the copy paste facility and that we
don't claim to support it, we can just noop this instruction.

cirrus_invalidate_region() calls memory_region_set_dirty()
on a per-line basis, always ranging from off_begin to
off_begin+bytesperline. With a negative pitch off_begin
marks the top most used address and thus we need to do an
initial shift backwards by a line for negative pitches of
backward blits, otherwise the first iteration covers the
line going from the start offset forwards instead of
backwards.
Additionally since the start address is inclusive, if we
shift by a full `bytesperline` we move to the first address
*not* included in the blit, so we only shift by one less
than bytesperline.

Delimit co_recv's lifetime clearly in aio_read_response.

Do a simple qemu_coroutine_enter in aio_read_response, letting
sd_co_writev call sd_write_done.

Handle nr_pending in the same way in sd_co_rw_vector,
sd_write_done and sd_co_flush_to_disk.

Remove sd_co_rw_vector's return value; just leave with no
pending requests.

[Jeff: added missing 'return' back, spotted by Paolo after
       series was applied.]

SheepdogAIOCB is internal to sheepdog.c, hence it is never canceled.

Macro calls without a trailing ; look weird in C, this works as a side
effect of how QEMU_BUILD_BUG_ON is implemented. Fix this up.

stub version of MISMATCH_CHECK is empty so it's easy to misuse for
people not building kvm on arm.  Use QEMU_BUILD_BUG_ON similar to the
non-stub version to make it easier to catch bugs.

The shpc component is optional while  ACPI hotplug is used
for hot-plugging PCI devices into a PCI-PCI bridge.
Disabling the shpc by default will make slot 0 usable at boot time
and not only for hot-plug, without loosing any functionality.
Older machines will have shpc enabled for compatibility reasons.
