[PATCH v3 00/17] ACPI: cleanups for hotplug

I'm working to make the Linux/ACPI code handle hotplug notification
events. This should ultimately allow us to remove the existing
hotplug code scattered through the ACPI device drivers.

This is a long series of cleanups that should cause no functional
change, but will make it easier to call acpi_bus_scan() from the
notification path.

Comments and testing reports welcome. Boot logs with
CONFIG_ACPI_DEBUG=y and "acpi.debug_layer=0x00010000" will be
helpful in debugging any issues.

Original posting: http://marc.info/?l=linux-acpi&m=124907619701194&w=2

Changes from v2 to v3:
- refreshed to apply on current acpi-test (193a6dec1c0246a).
- removed deferred execution patches (already in acpi-test)
- added fix for acpiphp_ibm.c bug introduced by ACPICA
acpi_get_object_info() changes (unrelated to this series, only
here for convenience)

Changes from initial post to v2:
- refreshed to apply on current acpi-test (0beab01e5b2c448).
- fixed memory leak in acpi_add_single_object() debug code
- added ACPI_IS_ROOT_DEVICE() macro (Len)
