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/ Conflicts: backends/baum.c backends/msmouse.c hw/a15mpcore.c hw/arm/Makefile.objs hw/arm/pic_cpu.c hw/dataplane/event-poll.c hw/dataplane/virtio-blk.c include/char/baum.h include/char/msmouse.h qemu-char.c vl.c Resolve conflicts caused by header movements.
