The latter is GPL which makes the whole of mini-os GPL rather than BSD as intended. In tree users are all GPL or GPL-compatible but we should fix this so that mini-os is BSD. Do so by using the same BSD sys/queue.h as we use in libxl. Tested with the builtin mini-os test app and qemu stubdomain, both of which appear to still function as expected. Move tools/libxl/external and the associated sed script to tools/include/xen-external to allow more sensible access from mini-os. Also add s/NULL/0/ in the sed script due to NULL not always being defined in stubdom code when mini-os/wait.h is included. As well as the obvious ABI changes there are a few API updates associated with the change: - struct rw_semaphore.wait_list is unused - remove_waiter needs to take the wait_queue_head The latter requires a qemu update, so there is also a QEMU_TAG update in this changeset. I sprinkled some extra-emacs local variables around the files I edited which didn't have them. I think this should be backported to the stable branches since external users of mini-os may have been mislead into thinking they could safely link mini-os against GPL-incompatible code.
