  hw/arm/aspeed: Do not create and attach empty SD cards by default
  hw/arm/palm.c: Encapsulate misc GPIO handling in a device
  hw/arm/palm.c: Detabify
  hw/arm/tosa: Encapsulate misc GPIO handling in a device
  hw/arm/tosa.c: Detabify
  hw/nios2: exit to main CPU loop only when unmasking interrupts
  target/nios2: Use gen_io_start around wrctl instruction
  target/nios2: in line the semantics of DISAS_UPDATE with other targets
  target/nios2: add DISAS_NORETURN case for nothing more to generate
  util/drm: make portable by avoiding struct dirent d_type
  util/oslib-posix.c: Implement qemu_init_exec_dir() for Haiku
