[Qemu-devel] [PATCH v3 0/2] vl.c: make current_machine as non-global variable

[Like Xu]

This patch makes the remaining dozen or so uses of the global
current_machine outside vl.c use qdev_get_machine() instead,
and then make current_machine local to vl.c instead of global.

With type assertion in qdev_get_machine(), it will be hard to
misuse this function if machine hasn't been created yet.
For obj-common cases, qdev_get_machine_uncheck() is applied
without semantic change.

---
Changes in v3:
    - add TYPE_MACHINE assertion for qdev_get_machine() usage
    - apply qdev_get_machine_uncheck() for obj-common usage
Changes in v2:
    - make the variable current_machine "static" (Thomas Huth)
