* remotes/bonzini/tags/for-upstream: (104 commits)
  WHPX: Assigning maintainer for Windows Hypervisor Platform
  accel/kvm: Check ioctl(KVM_SET_USER_MEMORY_REGION) return value
  target/i386: check for empty register in FXAM
  qdev-monitor: Forbid repeated device_del
  mem-prealloc: optimize large guest startup
  memory: batch allocate ioeventfds[] in address_space_update_ioeventfds()
  Avoid cpu_physical_memory_rw() with a constant is_write argument
  Let cpu_[physical]_memory() calls pass a boolean 'is_write' argument
  exec: Let cpu_[physical]_memory API use a boolean 'is_write' argument
  Avoid address_space_rw() with a constant is_write argument
  Let address_space_rw() calls pass a boolean 'is_write' argument
  exec: Let address_space_unmap() use a boolean 'is_write' argument
  hw/virtio: Let vhost_memory_map() use a boolean 'is_write' argument
  hw/virtio: Let virtqueue_map_iovec() use a boolean 'is_write' argument
  hw/ide: Let the DMAIntFunc prototype use a boolean 'is_write' argument
  hw/ide/internal: Remove unused DMARestartFunc typedef
  Remove unnecessary cast when using the cpu_[physical]_memory API
  exec: Let the cpu_[physical]_memory API use void pointer arguments
  Remove unnecessary cast when using the address_space API
  hw/net: Avoid casting non-const pointer, use address_space_write()
  ...
