[PATCH 1/3] fbmem: fix aperture overlapping check
fb_do_apertures_overlap is returning wrong value when one aperture is completely whithin the other. Add generic ranges_overlap macro (probably kernel.h candidate) and use it here.

[PATCH] vhost: Add vhost_commit callback for SeaBIOS ROM region re-mapping
...mmit() -> vhost_commit() callback. It addresses the case where virtio-scsi vq ioport RAM re-mapping to read-only SeaBIOS ROM triggers a cpu_physical_memory_map() NIL MemoryRegionSection pointer failure. Also save vhost_dev->mem_changed_[start,end]_addr values in vhost_set_memory() for final ranges_overlap checks. (Thanks Paolo!) Cc: Michael S.

[PATCH 0/3] virtio/vhost: Add checks for uninitialized VQs
From: Nicholas Bellinger <nab at linux-iscsi.org> Hi folks, This series adds a virtio_queue_valid() for use by virtio-pci code in order to prevent opreations upon uninitialized VQs, that is currently expected to occur during seabios setup of virtio-scsi. This also includes a vhost specific check for uninitialized VQs in vhost_verify_ring_mappings() to avoid this same case. Please review.

[PATCH 00/15] RFC xen device model support
Hi all, this is the long awaited patch series to add xen device model support in qemu; the main author is Anthony Perard. Developing this series we tried to come up with the cleanest possible solution from the qemu point of view, limiting the amount of changes to common code as much as possible. The end result still requires a couple of hooks in piix_pci but overall the impact should be very
