11380b3619 virtio: handle non-virtio-1-capable backend for ccw
If you run a qemu advertising VERSION_1 with an old kernel where
vhost did not yet support VERSION_1, you'll end up with a device
that is {modern pci|ccw revision 1} but does not advertise VERSION_1.
This is not a sensible configuration and is rejected by the Linux
guest drivers.

To fix this, add a ->post_plugged() callback invoked after features
have been queried that can handle the VERSION_1 bit being withdrawn
and change ccw to fall back to revision 0 if VERSION_1 is gone.

Note that pci is _not_ fixed; we'll need to rethink the approach
for the next release but at least for pci it's not a regression.

6d0b908a62 tests/vhost-user-bridge.c: fix fd leakage
This fixes file descriptor leakage in vhost-user-bridge
application. Whenever a new callfd or kickfd is set, the previous
one should be explicitly closed. File descriptors used to map
guest's memory are closed immediately after mmap call.

176c36997f mirror: Quiesce source during "mirror_exit"
With dataplane, the ioeventfd events could be dispatched after
mirror_run releases the dirty bitmap, but before mirror_exit actually
does the device switch, because the iothread will still be running, and
it will cause silent data loss.

Fix this by adding a bdrv_drained_begin/end pair around the window, so
that no new external request will be handled.

c2551b47c9 qcow2: Fix potential qemu-img check crash on 32 bit hosts
This crash was caught with qemu-iotests test case 138.

Commit b6d36de already fixed a few 32 bit truncation bugs that could
cause qemu-img check to allocate too little memory and consequently
it would segfault. On 32 bit hosts, there is one more place that needs
to be fixed because size_t was involved in the calculation and is a
32 bit type there.

0c2d70c448 translate-all: ensure host page mask is always extended with 1's
Anthony reported that >4GB guests on Xen with 32bit QEMU broke after
commit 4ed023c ("Round up RAMBlock sizes to host page sizes", 2015-11-05).

In that patch sizes are masked against qemu_host_page_size/mask which
are uintptr_t, and thus 32bit on a 32bit QEMU, even though the ram space
might be bigger than 4GB on Xen.

Since ram_addr_t is not available on user-mode emulation targets, ensure
that we get a sign extension when masking away the low bits of the address.
Remove the ~10 year old scary comment that the type of these variables
is probably wrong, with another equally scary comment.  The new comment
however does not have "???" in it, which is arguably an improvement.

For completeness use the alignment macros in linux-user and bsd-user
instead of manually doing an &.  linux-user and bsd-user are not affected
by the Xen issue, however.

8d3a5d9b0f ui/cocoa.m: Prevent activation clicks from going to guest
When QEMU is brought to the foreground, the click event that activates QEMU
should not go to the guest. Accidents happen when they do go to the guest
without giving the user a chance to handle them. In particular, if the
guest input device is not an absolute-position one then the location of
the guest cursor (and thus the click) will likely not be the location of
the host cursor when it is clicked, and could be completely obscured
below another window. Don't send mouse clicks to QEMU unless the
window either has focus or has grabbed mouse events.

f0a399dbae s390x/pci: fix up IOMMU size
Present code uses @size==UINT64_MAX to initialize IOMMU. It infers that it
can map any 64-bit IOVA whatsoever. But in fact, the largest DMA range for
each PCI Device on s390x is from ZPCI_SDMA_ADDR to ZPCI_EDMA_ADDR. The largest
value is returned from hardware, which is to indicate the largest range
hardware can support. But the real IOMMU size for specific PCI Device is
obtained once qemu intercepts mpcifc instruction that guest is requesting a
DMA range for that PCI Device. Therefore, before intercepting mpcifc instruction,
qemu cannot be aware of the size of IOMMU region that guest will use.

Moreover, iommu replay during device initialization for the whole region in
4k steps takes a very long time.

In conclusion, this patch intializes IOMMU region for each PCI Device when
intercept mpcifc instruction which is to register DMA range for the PCI Device.
And then, destroy IOMMU region when guest wants to deregister IOAT.

Newer distributions have an architecture level set to z9, z196

We should build the bios for z900 to allow it to run with
all 64bit CPUs. This will become more important as soon as
QEMU/KVM does support CPU models.

e2a176dfda hw/ppc/ppc405_boards: Fix infinite recursion by converting taihu_cpld from old_mmio
The taihu_cpld_writel() function had an obvious typo that meant that
if it was ever called it would go into an infinite recursion. Newer
versions of clang will detect and warn about this:
  hw/ppc/ppc405_boards.c:481:1: warning: all paths through this function will call itself [-Winfinite-recursion]

Fix this by converting taihu_cpld from the legacy old_mmio accessors
to new-style ones, with an impl {} declaration to cause the core
memory code to do the splitting of 16 bit and 32 bit accesses into
multiple 8-bit accesses.

b73c184914 tap-win32: disable broken async write path
The code under the TUN_ASYNCHRONOUS_WRITES path makes two incorrect
assumptions about the behaviour of the WriteFile API for overlapped
file handles. First, WriteFile does not update the
lpNumberOfBytesWritten parameter when the write completes
asynchronously (the number of bytes written is known only when the
operation completes). Second, the buffer shouldn't be touched (or
freed) until the operation completes. This led to at least one bug
where tap_win32_write returned zero bytes written, which in turn
caused further writes ("receives") to be disabled for that device.

This change disables the asynchronous write path, while keeping most
of the code around in case someone sees value in resurrecting it. It
also adds some conditional debug output, similar to the read path.

ee0428e3ac tap-win32: skip unexpected nodes during registry enumeration
In order to find a named tap device, get_device_guid() enumerates children of
HKLM\SYSTEM\CCS\Control\Network\{4D36E972-E325-11CE-BFC1-08002BE10318}
(aka NETWORK_CONNECTIONS_KEY). For each child, it then looks for a
"Connection" subkey, but if this key doesn't exist, it aborts the
entire search. This was observed to fail on at least one Windows 10
machine, where there is an additional child of NETWORK_CONNECTIONS_KEY
(named "Descriptions"). Since registry enumeration doesn't guarantee
any particular sort order, we should continue to search for matching
children rather than aborting the search.

5120901a37 target-i386: kvm: Print warning when clearing mcg_cap bits
Instead of silently clearing mcg_cap bits when the host doesn't
support them, print a warning when doing that.

2590f15b13 target-i386: kvm: Use env->mcg_cap when setting up MCE
When setting up MCE, instead of using the MCE_*_DEF macros
directly, just filter the existing env->mcg_cap value.

As env->mcg_cap is already initialized as
MCE_CAP_DEF|MCE_BANKS_DEF at target-i386/cpu.c:mce_init(), this
doesn't change any behavior. But it will allow us to change
mce_init() in the future, to implement different defaults
depending on CPU model, machine-type or command-line parameters.
