2014-06-19pc: implement pc-dimm device abstractionVasilis Liaskovitis
Each hotplug-able memory slot is a PCDIMMDevice. A hot-add operation for a memory device: - creates a new PCDIMMDevice and makes hotplug controller to map it into guest address space Hotplug operations are done through normal device_add commands. For migration case, all hotplugged memory devices on source should be specified on target's command line using '-device' option with properties set to the same values as on source. To simplify review, patch introduces only PCDIMMDevice QOM skeleton that will be extended by following patches to implement actual memory hotplug and related functions.

2014-06-17linux-user: Don't overrun guest buffer in sched_getaffinityPeter Maydell
If the guest's "long" type is smaller than the host's, then our sched_getaffinity wrapper needs to round the buffer size up to a multiple of the host sizeof(long). This means that when we copy the data back from the host buffer to the guest's buffer there might be more than we can fit. Rather than overflowing the guest's buffer, handle this case by returning EINVAL or ignoring the unused extra space, as appropriate. Note that only guests using the syscall interface directly might run into this bug -- the glibc wrappers around it will always use a buffer whose size is a multiple of 8 regardless of guest architecture.
