97ff87c0ed qemu/compiler: Wrap __attribute__((flatten)) in a macro
Older versions of Clang (before 3.5) and GCC (before 4.1) do not
support the "__attribute__((flatten))" yet. We don't care about
such old versions of GCC anymore, but since Clang 3.4 is still
used in EPEL for RHEL7 / CentOS 7, we should not use this attribute
directly but with a wrapper macro instead.

5f538f7532 target/hppa: Raise exception 26 on emulated hardware
On PCXS chips (PA7000, pa 1.1a), trap #18 is raised on memory faults,
while all later chips (>= PA7100) generate either trap #26, #27 or #28
(depending on the fault type).

Since the current qemu emulation emulates a B160L machine (with a
PA7300LC PCX-L2 chip, we should raise trap #26 (EXCP_DMAR) instead
of #18 (EXCP_DMP) on access faults by the Linux kernel to page zero.

With the patch we now get the correct output (I tested against real
hardware):
 Kernel Fault: Code=26 (Data memory access rights trap)
instead of:
 Kernel Fault: Code=18 (Data memory protection/unaligned access trap)

2ef297af07 coccinelle: new inplace-byteswaps.cocci to remove inplace-byteswapping calls
Add a new Coccinelle script which replaces uses of the inplace
byteswapping functions *_to_cpus() and cpu_to_*s() with their
not-in-place equivalents. This is useful for where the swapping
is done on members of a packed struct -- taking the address
of the member to pass it to an inplace function is undefined
behaviour in C.

ab44c7b71f target/arm: Initialize ARMMMUFaultInfo in v7m_stack_read/write
The get_phys_addr() functions take a pointer to an ARMMMUFaultInfo
struct, which they fill in only if a fault occurs. This means that
the caller must always zero-initialize the struct before passing
it in. We forgot to do this in v7m_stack_read() and v7m_stack_write().

7a6c377f6b tests: Prevent more accidental test disabling
GNU make is perfectly happy to use 'check-FOO-y += bar' to
initialize check-FOO-y.  (GNU Automake strictly insists that
you cannot use += until after an initial = per variable, but
thankfully we aren't using automake).

As we have had more than one instance where copy-and-paste of
'check-FOO-y = bar' from a first test under category FOO into
an additional test, which ends up disabling the first (see
commits 992159c7 and 4429532b), it's better to just always use
the form that survives copy-and-paste, even for categories that
don't currently add more than one test.

Done with s/^\(check-[a-z]*-y \)=/\1+=/g

af7d64ede0 hw/arm/sysbus-fdt: Allow device matching with DT compatible value
Up to now we have relied on the device type to identify a device tree
node creation function.  Since we would like the vfio-platform device to
be instantiable with different compatible strings we introduce the
capability to specialize the node creation depending on actual
compatible value.

NodeCreationPair is renamed into BindingEntry. The struct is enhanced
with compat and match_fn() fields.  We introduce a new matching function
adapted to the vfio-platform generic device.

Soon, the AMD XGBE can be instantiated with either manner, i.e.:

    -device vfio-amd-xgbe,host=e0900000.xgmac

or using the new option line:

    -device vfio-platform,host=e0900000.xgmac

a49531ebd0 vfio/platform: Make the vfio-platform device non-abstract
Up to now the vfio-platform device has been abstract and could not be
instantiated.  The integration of a new vfio platform device required
creating a dummy derived device which only set the compatible string.

Following the few vfio-platform device integrations we have seen the
actual requested adaptation happens on device tree node creation
(sysbus-fdt).

Hence remove the abstract setting, and read the list of compatible
values from sysfs if not set by a derived device.

Update the amd-xgbe and calxeda-xgmac drivers to fill in the number of
compatible values, as there can now be more than one.

Note that sysbus-fdt does not support the instantiation of the
vfio-platform device yet.

b290659fc3 hw/vfio/display: add ramfb support
So we have a boot display when using a vgpu as primary display.

ramfb depends on a fw_cfg file.  fw_cfg files can not be added and
removed at runtime, therefore a ramfb-enabled vfio device can't be
hotplugged.

Add a nohotplug variant of the vfio-pci device (as child class).  Add
the ramfb property to the nohotplug variant only.  So to enable the vgpu
display with boot support use this:

  -device vfio-pci-nohotplug,display=on,ramfb=on,sysfsdev=...

ce3cf70eda hw/display/cirrus_vga: Move "isa-cirrus-vga" device into a separate file
In downstream distros like RHEL we'd like to disable some of the "legacy"
devices of QEMU. The ISA version of the Cirrus VGA device is one of these
legacy devices. So let's make the build process a little bit more flexible
here by putting the Cirrus ISA code into a separate file which is only
included if both, CONFIG_VGA_CIRRUS and CONFIG_VGA_ISA are set.

Note that this disables "isa-cirrus-vga" for the ppc-softmmu and the
alpha-softmmu target since CONFIG_VGA_ISA is not set there. But I think
this is OK since these targets are only interested in the PCI variant
anyway.

  FreeBSD (Ports): 3.22.29
  OpenSUSE Leap 15: 3.22.30
  SLE12-SP2: Unknown
  Ubuntu (Xenial): 3.18.9
  macOS (Homebrew): 3.22.30

This suggests that a minimum GTK3 of 3.14.0 is a reasonable target,
as users are unlikely to be stuck on RHEL-7.0/7.1 still

    The GTK 3.0 release was made in Feb, 2011:

      https://blog.gtk.org/2011/02/10/gtk-3-0-released/

    That will soon be 7 years ago, which is enough time to consider
    the 3.x series widely supported.

    Thus we deprecate the GTK 2.x support, which will allow us to
    delete it in the last release of 2018. By this time, GTK 3.x
    will be almost 8 years old.
