Anthony Liguori 6e72a00f90 Merge remote-tracking branch 'bonzini/hw-dirs' into staging
* bonzini/hw-dirs:
  sh: move files referencing CPU to hw/sh4/
  ppc: move more files to hw/ppc
  ppc: move files referencing CPU to hw/ppc/
  m68k: move files referencing CPU to hw/m68k/
  i386: move files referencing CPU to hw/i386/
  arm: move files referencing CPU to hw/arm/
  hw: move boards and other isolated files to hw/ARCH
  ppc: express FDT dependency of pSeries and e500 boards via default-configs/
  build: always link device_tree.o into emulators if libfdt available
  hw: include hw header files with full paths
  ppc: do not use ../ in include files
  vt82c686: vt82c686 is not a PCI host bridge
  virtio-9p: remove PCI dependencies from hw/9pfs/
  virtio-9p: use CONFIG_VIRTFS, not CONFIG_LINUX
  hw: move device-hotplug.o to toplevel, compile it once
  hw: move qdev-monitor.o to toplevel directory
  hw: move fifo.[ch] to libqemuutil
  hw: move char backends to backends/
