David Hildenbrand 7f863cba4d softmmu/memory: Pass ram_flags to memory_region_init_ram_shared_nomigrate() 
Let's forward ram_flags instead, renaming
memory_region_init_ram_shared_nomigrate() into
memory_region_init_ram_flags_nomigrate().

Philippe Mathieu-Daudé 84969111e6 scripts/cocci: Patch to let devices own their MemoryRegions 
When a device creates a MemoryRegion without setting its ownership,
the MemoryRegion is added to the machine "/unattached" container in
the QOM tree.

Example with the Samsung SMDKC210 board:

  $ arm-softmmu/qemu-system-arm -M smdkc210 -S -monitor stdio
  (qemu) info qom-tree
  /machine (smdkc210-machine)
    /unattached (container)
      /io[0] (qemu:memory-region)
      /exynos4210.dram0[0] (qemu:memory-region)
      /exynos4210.irom[0] (qemu:memory-region)
      /exynos4210.iram[0] (qemu:memory-region)
      /exynos4210.chipid[0] (qemu:memory-region)
      ...
      /device[26] (exynos4210.uart)
        /exynos4210.uart[0] (qemu:memory-region)
    /soc (exynos4210)
      ^
       \__ [*]

The irom/iram/chipid regions should go under 'soc' at [*].

Add a semantic patch to let the device own the memory region.

Philippe Mathieu-Daudé 044e2af9f5 scripts/cocci: Rename memory-region-{init-ram -> housekeeping} 
As we are going to add various semantic changes related to the memory
region API, rename this script to be more generic.
Add a 'usage' header, and an entry in MAINTAINERS to avoid checkpatch
warning.
