* remotes/bonzini/tags/for-upstream: (34 commits)
  avoid TABs in files that only contain a few
  remove space-tab sequences
  scripts: add script to convert multiline comments into 4-line format
  hw/watchdog/wdt_i6300esb: remove a unnecessary comment
  checkpatch: warn about qemu/queue.h head structs that are not typedef-ed
  qemu/queue.h: simplify reverse access to QTAILQ
  qemu/queue.h: reimplement QTAILQ without pointer-to-pointers
  qemu/queue.h: remove Q_TAILQ_{HEAD,ENTRY}
  qemu/queue.h: typedef QTAILQ heads
  qemu/queue.h: leave head structs anonymous unless necessary
  vfio: make vfio_address_spaces static
  qemu/queue.h: do not access tqe_prev directly
  test: replace gtester with a TAP driver
  test: execute g_test_run when tests are skipped
  qga: drop < Vista compatibility
  build-sys: build with Vista API by default
  build-sys: move windows defines in osdep.h header
  build-sys: don't include windows.h, osdep.h does it
  scsi: esp: Defer command completion until previous interrupts have been handled
  esp-pci: Fix status register write erase control
