Merge remote-tracking branch 'mjt/trivial-patches' into staging

* mjt/trivial-patches:
  acpi unit-test: Remove temporary disk after test
  mainstone: Fix duplicate array values for key 'space'
  pxa27x: Add 'const' attribute to keyboard maps
  pxa27x: Reduce size of keyboard matrix mapping
  doc: Mention chardev:id in available devices for -serial
  configure: Python tests must be done before help message
  configure: Rewrite code for help message
  fix -boot strict regressed in commit 6ef4716
  vl: make boot_strict variable static (not used outside vl.c)
  x86: only allow real mode to access 32bit without LMA
  linux-user: Use macro TARGET_NSIG_WORDS where possible
  exynos4210: Use macro ARRAY_SIZE where possible
  ui/cocoa: Use macro ARRAY_SIZE where possible
  misc: Use macro ARRAY_SIZE where possible
  openrisc: Fix spelling in comment (transaltion -> translation)
  hw/arm/highbank: Simplify code (memory region in device state)
