Merge remote-tracking branch 'qemu-kvm/uq/master' into staging

* qemu-kvm/uq/master:
  kvm: Rename irqchip_inject_ioctl to irq_set_ioctl
  kvm: Stop flushing coalesced MMIO on vmexit
  VGA: Flush coalesced MMIO on related MMIO/PIO accesses
  memory: Flush coalesced MMIO on mapping and state changes
  memory: Fold memory_region_update_topology into memory_region_transaction_commit
  memory: Use transaction_begin/commit also for single-step operations
  memory: Flush coalesced MMIO on selected region access
  kvm-all.c: Move init of irqchip_inject_ioctl out of kvm_irqchip_create()
  update-linux-headers.sh: Don't hard code list of architectures
