2017-06-13hw/intc/exynos4210_gic: Use more meaningful name for local variableKrzysztof Kozlowski
There are to SysBusDevice variables in exynos4210_gic_realize() function: one for the device itself and second for arm_gic device. Add a prefix "gic" to the second one so it will be easier to understand the code. While at it, put local uninitialized 'i' variable at the end, next to other uninitialized ones.

In external_snapshot_abort(), we try to undo what was done in external_snapshot_prepare() calling bdrv_replace_node() to swap the nodes back. However, we receive a permissions error as writers are blocked on the old node, which is now the new node backing file.

2017-06-09commit: Fix use after free in completionKevin Wolf
The final bdrv_set_backing_hd() could be working on already freed nodes because the commit job drops its references (through BlockBackends) to both overlay_bs and top already a bit earlier. One way to trigger the bug is hot unplugging a disk for which blockdev_mark_auto_del() cancels the block job. Fix this by taking BDS-level references while we're still using the nodes.

Block migration may still access the image during its .save_live_complete_precopy() implementation, so we should only inactivate the image afterwards. Another reason for the change is that inactivating an image fails when there is still a non-device BlockBackend using it, which includes the BBs used by block migration.

This reverts commit fe6824d12642b005c69123ecf8631f9b13553f8b. Conflicts hw/ppc/spapr_drc.c, because get_index() has been renamed spapr_get_index(). This didn't fix the problem. Once the hotplug has been started some memory is allocated and some structures are allocated. We don't free it when we ignore the unplug, and we can't because they can be in use by the kernel.

2017-06-09xics: setup cpu at realize timeGreg Kurz
Until recently, spapr used to allocate ICPState objects for the lifetime of the machine. They would only be associated to vCPUs in xics_cpu_setup() when plugging a CPU core. Now that ICPState objects have the same lifecycle as vCPUs, it is possible to associate them during realization. This patch hence open-codes xics_cpu_setup() in icp_realize(). The vCPU is passed as a property. Note that vCPU now needs to be realized first for the IRQs to be allocated. It also needs to resetted before ICPState realization in order to synchronize with KVM. Since ICPState objects are freed when unrealized, xics_cpu_destroy() isn't needed anymore and can be safely dropped.

2017-06-08hw/ppc/spapr: Adjust firmware name for PCI bridgesThomas Huth
SLOF uses "pci" as name for PCI bridges nodes in the device tree instead of "pci-bridges", so booting via bootindex from a device behind a PCI bridge currently does not work since QEMU passes the wrong name in the "qemu,boot-list" property. Fix it by changing the name of the PCI bridge nodes to "pci" instead.

2017-06-08xics: add reset() handler to ICPStateClassGreg Kurz
Taking into account that qemu_set_irq() returns immediatly if its first argument is NULL, icp_kvm_reset() largely duplicates icp_reset(). This patch introduces a reset() handler, so that the common logic can be implemented in icp_reset() only. While there we can also drop icp_kvm_realize() and icp_kvm_unrealize(). This causes icp-kvm to be realized in icp_realize(), which sets icp->xics, but it has no impact.

2017-06-08pnv_core: drop reference on ICPState object during CPU realizationGreg Kurz
Similarly to what was done to spapr with commit 249127d0dfeb, this patch ensures that we don't keep an extra reference on the ICPState object. Also since the object was just created and not reparented yet, the call to object_property_add_child() should never fail: let's pass &error_abort to make this clear.

2017-06-08spapr: Rework DRC name handlingDavid Gibson
DRC objects have a get_name method which returns the DRC name generated when the DRC is created. Replace that with a fixed spapr_drc_name() function which generates the name on the fly from other information. This means: * We get rid of a method with only one implementation, and only local callers * We don't have to carry the name string around for the lifetime of the DRC * We use information added to the class structure to generate the name in standard format, so we don't need an explicit switch on drc type any more We also eliminate the 'name' property; it's basically useless since the only information in it can easily be deduced from other things.
