Even though our -cpu types for e500mc and e5500 are no real CPUs that
actually have version registers, a guest might still want to access
said version register and that has to succeed for a guest to be happy.
So let's expose a zero SVR value on E500_SVR SPR reads.

We have 3 blobs we need to load when booting the system:
- kernel
- initrd
- dtb
We place them in physical memory in that order. At least we should.
This patch fixes the location calculation up to take any module into
account, fixing the dtb offset along the way.

The Raven MPIC implementation supports the "Mixed" mode to work with
an i8259. While we don't implement mixed mode, we should mark it as
a supported mode in the mode bitmap.

The mode mask already masks out bits we don't care about, so the

The viostor virtio-blk driver for Windows does not use the
VIRTIO_CONFIG_S_DRIVER bit. It only sets the VIRTIO_CONFIG_S_DRIVER_OK
bit.
The viostor driver refreshes the virtio-pci status byte sometimes while
the guest is running. We misinterpret 0x4 (VIRTIO_CONFIG_S_DRIVER_OK)
as an indication that virtio-blk-data-plane should be stopped since 0x2
(VIRTIO_CONFIG_S_DRIVER) is missing. The result is that the device
becomes unresponsive.

When dataplane is stopping, the s->vdev->binding->set_host_notifier(...,
false) call can invoke the virtqueue handler if an ioeventfd
notification is pending. This causes hw/virtio-blk.c to invoke
virtio_blk_data_plane_start() before virtio_blk_data_plane_stop()
returns!
The result is that we try to restart dataplane while trying to stop it
and the following assertion is raised:
msix_set_mask_notifier: Assertion `!dev->msix_mask_notifier' failed.
Although the code was intended to prevent this scenario, the s->started
boolean isn't enough. Add s->stopping so that we can postpone clearing
s->started until we've completely stopped dataplane.
This way, virtqueue handler calls during virtio_blk_data_plane_stop()
are ignored. When dataplane is legitimately started again later we
already self-kick ourselves to resume processing.

Commit eb8eb53e5846a957cf333f2e1ec8cb6e0c04 ("libcacard: rewrite
Makefile in non-recursive style") refactored libcacard/Makefile so it
can be included by the top-level Makefile.
The top-level clean target still loops over subdirectories, including
libcacard/, to invoke recursive clean. Remove libcacard from the
recursive clean since its files are already included at the top level.

aio_poll() must return true if any work is still pending, even if it
didn't make progress, so that bdrv_drain_all() doesn't stop waiting too
early. The possibility of stopping early occasionally lead to a failed
assertion in bdrv_drain_all(), when some in-flight request was missed
and the function didn't really drain all requests.
In order to make that change, the return value as specified in the
function comment must change for blocking = false; fortunately, the
return value of blocking = false callers is only used in test cases, so
this change shouldn't cause any trouble.

This is a bug that was caught by a coverity run by Markus. In
the error case when we errored out to exit_restore_open early in the
function, 'overlay_bs' was still NULL at that point, although it is
used to look up flags and perform a bdrv_reopen().
Move the overlay_bs lookup to where it is needed, and check for NULL
before restoring the flags. Also get rid of the unneeded parameter
initialization.

OpenBSD system compiler (gcc 4.2.1) has problems with concatenation
of macro arguments in macro functions:
CC aes.o
In file included from /src/qemu/include/qemu-common.h:126,
from /src/qemu/aes.c:30:
/src/qemu/include/qemu/bswap.h: In function 'leul_to_cpu':
/src/qemu/include/qemu/bswap.h:461: warning: implicit declaration of function 'bswapHOST_LONG_BITS'
/src/qemu/include/qemu/bswap.h:461: warning: nested extern declaration of 'bswapHOST_LONG_BITS'
Function leul_to_cpu() is only used in kvm-all.c, so the warnings
are not fatal on OpenBSD without -Werror.
Fix by applying glue(). Also add do {} while(0) wrapping and fix
semicolon use while at it.

The version.o file did not appear explicitly as a dependency, and
this caused clean builds to fail. Force its build by making the
Makefile depend on version.o.
(We cannot add it to libqemuutil.a, because it doesn't export any
symbol and thus would not be pulled by the linker).

An early length postincrement in the TMP105's I2C TX path led to
transfers of more than one byte to place the second byte in the third
byte's place within the buffer and the third byte to get discarded.
Fix this by explictly incrementing the length after the checks but
before the callback is called, which again checks the length.
