[Qemu-devel] [PATCH 00/11] pc: kvm: memory hotplug fixes

[Igor Mammedov <imammedo@redhat.com>]

Series 
  * fixes [1/11] QEMU crash when non aligned DIMM is used in KVM mode.
  * adds extra checks/enforcement to avoid non aligned DIMM address/sizes
    and prevents guest failures when it tries to deal with such DIMMs
  * prevents QEMU from starting with not baked by KVM amount of
    memory slots
  * fixes hotplug-memory region fragmentation, enabled for 2.2 and newer
  * enforces backend alignment on DIMMs address/size for optimal
    performance, enabled for 2.2 and newer
  

Igor Mammedov (11):
  pc: kvm: check if KVM has free memory slots to avoid abort()
  kvm: provide API to query amount of memory slots supported by KVM
  pc: check if KVM has enough memory slots for DIMM devices
  pc: make pc_dimm_plug() more readble
  pc: limit DIMM address and size to page aligned values
  memory: expose alignment used for allocating RAM as MemoryRegion API
  pc: add pc_init_pci_2_1() and pc_compat_2_1()
  pc: align DIMM's address/size by backend's alignment value
  pc: pc-dimm: use backend alignment during address auto allocation
  pc: explicitly check maxmem limit when adding DIMM
  pc: count in 1Gb hugepage alignment when sizing hotplug-memory
    container
