[Qemu-devel] [PATCH v3 0/5] Refactoring pc_dimm_plug and NUMA node lookup API |

Hi,
Here is the v3 of the patchset that refactors pc_dimm_plug and adds
an API to lookup NUMA node by address.
- Refactoring pc_dimm_plug() helps other architectures like PowerPC
to make use of common code.
- API to lookup NUMA node id by address is required to support memory
hotplug on PowerPC sPAPR guests.
The patchset that adds memory hotplug support to PowerPC sPAPR that
was posted at
http://lists.nongnu.org/archive/html/qemu-devel/2015-06/msg06574.html
depends on this patchset.
Changes in v3:
-------------
- Not calling pc_dimm_memory_unplug() when pc_dimm_memory_plug() fails
because when pc_dimm_memory_plug() fails, it wouldn't have done
memory_region_add_subregion() and vmstate_register_ram().
- As per Igor's suggestion, moving of hotplug related fields from
PCMachineState is now in a separate patch.
v2: https://lists.gnu.org/archive/html/qemu-devel/2015-06/msg05157.html
v1: https://lists.gnu.org/archive/html/qemu-devel/2015-06/msg03212.html
v0: https://lists.gnu.org/archive/html/qemu-devel/2015-05/msg01078.html
Bharata B Rao (5):
pc,pc-dimm: Extract hotplug related fields in PCMachineState to a
structure
pc,pc-dimm: Factor out reusable parts in pc_dimm_plug to a separate
routine
numa,pc-dimm: Store pc-dimm memory information in numa_info
numa: Store boot memory address range in node_info
numa: API to lookup NUMA node by address
