linux-user: Fix inotify_init1 support
This commit adds necessary conversion of argument passed to inotify_init1.
inotify_init1 flags can be IN_NONBLOCK and IN_CLOEXEC which rely on O_NONBLOCK

target/openrisc: Fix exception handling status registers
I am working on testing instruction emulation patches for the linux
kernel. During testing I found these 2 issues:
- sets DSX (delay slot exception) but never clears it
- EEAR for illegal insns should point to the bad exception (as per
openrisc spec) but its not
This patch fixes these two issues by clearing the DSX flag when not in a
delay slot and by setting EEAR to exception PC when handling illegal
instruction exceptions.
After this patch the openrisc kernel with latest patches boots great on
qemu and instruction emulation works.

migration: Add VMSTATE_WITH_TMP
VMSTATE_WITH_TMP is for handling structures where some calculation
or rearrangement of the data needs to be performed before the data
hits the wire.
For example, where the value on the wire is an offset from a
non-migrated base, but the data in the structure is the actual pointer.
To use it, a temporary type is created and a vmsd used on that type.
The first element of the type must be 'parent' a pointer back to the
type of the main structure. VMSTATE_WITH_TMP takes care of allocating
and freeing the temporary before running the child vmsd.
The post_load/pre_save on the child vmsd can copy things from the parent
to the temporary using the parent pointer and do any other calculations
needed; it can then use normal VMSD entries to do the actual data
storage without having to fiddle around with qemu_get_*/qemu_put_*

strtoul() to an 'int' variable and then tries to check for > INT_MAX.

Rewrite to use qemu_strtoul(), which has a saner convention for

qcow2: Optimize the refcount-block overlap check
The metadata overlap checks introduced in
a40f1c2add help detect
corruption in the qcow2 image by verifying that data writes don't
overlap with existing metadata sections.
The 'refcount-block' check in particular iterates over the refcount
table in order to get the addresses of all refcount blocks and check
that none of them overlap with the region where we want to write.
The problem with the refcount table is that since it always occupies
complete clusters its size is usually very big. With the default
values of cluster_size=64KB and refcount_bits=16 this table holds 8192
entries, each one of them enough to map 2GB worth of host clusters.
So unless we're using images with several TB of allocated data this
table is going to be mostly empty, and iterating over it is a waste of
CPU. If the storage backend is fast enough this can have an effect on
I/O performance.
This patch keeps the index of the last used (i.e. non-zero) entry in
the refcount table and updates it every time the table changes. The
refcount-block overlap check then uses that index instead of reading
the whole table.
In my tests with a 4GB qcow2 file stored in RAM this doubles the
amount of write IOPS.

94d6a7a accidentally left the naming of runtime opts and QAPI

Please note that this is technically backwards incompatible with the 2.8

block: check full backing filename when searching protocol filenames
In bdrv_find_backing_image(), if we are searching an image for a backing
file that contains a protocol, we currently only compare unmodified
paths.
However, some management software will change the backing filename to be
a relative filename in a path. QEMU is able to handle this fine,
because internally it will use path_combine to put together the full
protocol URI.
However, this can lead to an inability to match an image during a QAPI
command that needs to use bdrv_find_backing_image() to find the image,
when it is searched by the full URI.
When searching for a protocol filename, if the straight comparison
fails, this patch will also compare against the full backing filename to
see if that is a match.

block/vmdk: Fix the endian problem of buf_len and lba
The problem was triggered by qemu-iotests case 055. It failed when it

The cause is that buf_len in vmdk_write_extent wasn't converted to
little-endian before it was stored to disk. But later vmdk_read_extent
read it and converted it from little-endian to cpu endian.
If the cpu is big-endian like s390, the problem will happen and
the data length read by vmdk_read_extent will become invalid!
The fix is to add the conversion in vmdk_write_extent, meanwhile,
repair the endianness problem of lba field which shall also be converted

iotests: Fix a problem in common.filter
If TEST_DIR is set to /tmp, test case 144 will fail. The reason is that
TEST_DIR resembles 144's test image name tmp.qcow2.
When 144 is testing $TEST_DIR/tmp.qcow2, it wants to replace
$TEST_DIR/tmp.qcow2 to TEST_DIR/tmp.qcow2, but actually it will fail
and get TEST_DIRTEST_DIR.qcow2 in this case.
The fix is just to modify the code to replace $TEST_DIR/ with TEST_DIR/.

hw/vfio: Add CONFIG switches for calxeda-xgmac and amd-xgbe
Both devices seem to be specific to the ARM platform. It's confusing
for the users if they show up on other target architectures, too
(e.g. when the user runs QEMU with "-device ?" to get a list of
supported devices). Thus let's introduce proper configuration switches
so that the devices are only compiled and included when they are
really required.

vfio-pci: Fix GTT wrap-around for Skylake+ IGD
Previous IGD, up through Broadwell, only seem to write GTT values into
the first 1MB of space allocated for the BDSM, but clearly the GTT
can be multiple MB in size. Our test in vfio_igd_quirk_data_write()
correctly filters out indexes beyond 1MB, but given the 1MB mask we're
using, we re-apply writes only to the first 1MB of the guest allocated
BDSM.
We can't assume either the host or guest BDSM is naturally aligned, so
we can't simply apply a different mask. Instead, save the host BDSM
and do the arithmetic to subtract the host value to get the BDSM
offset and add it to the guest allocated BDSM.

The AHCI emulation code supports 64-bit addressing and should advertise this

cirrus: fix patterncopy checks
The blit_region_is_unsafe checks don't work correctly for the
patterncopy source. It's a fixed-sized region, which doesn't
depend on cirrus_blt_{width,height}. So go do the check in
cirrus_bitblt_common_patterncopy instead, then tell blit_is_unsafe that
it doesn't need to verify the source. Also handle the case where we
blit from cirrus_bitbuf correctly.
This patch replaces
5858dd1801883309bdd208d72ddb81c4e9fee30c.
Security impact: I think for the most part error on the safe side this
time, refusing blits which should have been allowed.
Only exception is placing the blit source at the end of the video ram,
so cirrus_blt_srcaddr + 256 goes beyond the end of video memory. But
even in that case I'm not fully sure this actually allows read access to
host memory. To trick the commit
5858dd18 security checks one has to
pick very small cirrus_blt_{width,height} values, which in turn implies
only a fraction of the blit source will actually be used.

we can speed up the test by running QEMU with "-nodefaults" for
the pseries machine, so that SLOF has less devices to scan during
boot, and by using the "nvramrc" environment variable instead of
"boot-command", since this variable is evaluated earlier in the
boot process.
And to be really sure that we do not face such time out problems
