2009-03-27ACPI: call acpi_wakeup_device_init() explicitly rather than as initcallBjorn Helgaas
This patch makes acpi_init() call acpi_wakeup_device_init() directly. Previously, acpi_wakeup_device_init() was a late_initcall (sequence 7). acpi_wakeup_device_init() depends on acpi_wakeup_device_list, which is populated when ACPI devices are enumerated by acpi_init() -> acpi_scan_init(). Using late_initcall is certainly enough to make sure acpi_wakeup_device_list is populated, but it is more than necessary. We can just as easily call acpi_wakeup_device_init() directly from acpi_init(), which avoids the initcall magic.

2009-03-27ACPI: call acpi_sleep_proc_init() explicitly rather than as initcallBjorn Helgaas
This patch makes acpi_init() call acpi_sleep_proc_init() directly. Previously, acpi_sleep_proc_init() was a late_initcall (sequence 7), apparently to make sure that the /proc hierarchy already exists: 2003/02/13 12:38:03-06:00 mochel acpi sleep: demote sleep proc file creation. - Make acpi_sleep_proc_init() a late_initcall(), and not called from acpi_sleep_init(). This guarantees that the acpi proc hierarchy is at least there when we create the dang file. This should no longer be an issue because acpi_bus_init() (called early in acpi_init()) creates acpi_root_dir (/proc/acpi).

2009-03-27ACPI: call init_acpi_device_notify() explicitly rather than as initcallBjorn Helgaas
This patch makes acpi_init() call init_acpi_device_notify() directly. Previously, init_acpi_device_notify() was an arch_initcall (sequence 3), so it was called before acpi_init() (a subsys_initcall at sequence 4). init_acpi_device_notify() sets the platform_notify and platform_notify_remove function pointers. These pointers are not used until acpi_init() enumerates ACPI devices in this path: acpi_init() acpi_scan_init() acpi_bus_scan() acpi_add_single_object() acpi_device_register() device_add() <use platform_notify> So it is sufficient to have acpi_init() call init_acpi_device_notify() directly before it enumerates devices.

2009-03-27ACPI: call acpi_debug_init() explicitly rather than as initcallBjorn Helgaas
This patch makes acpi_init() call acpi_debug_init() directly. Previously, both were subsys_initcalls. acpi_debug_init() must happen after acpi_init(), and it's better to call it explicitly rather than rely on link ordering.

2009-03-27ACPI: call acpi_scan_init() explicitly rather than as initcallBjorn Helgaas
This patch makes acpi_init() call acpi_scan_init() directly. Previously, both acpi_init() and acpi_scan_init() were subsys_initcalls, and acpi_init() was called first based on the link order from the makefile (bus.o before scan.o). acpi_scan_init() registers the ACPI bus type, creates the root device, and enumerates fixed-feature and namespace devices. All of this must be done after acpi_init(), and it's better to call acpi_scan_init() explicitly rather than rely on the link ordering.

2009-03-17ACPI: move private declarations to internal.hBjorn Helgaas
A number of things that shouldn't be exposed outside the ACPI core were declared in include/acpi/acpi_drivers.h, where anybody can see them. This patch moves those declarations to a new "internal.h" inside drivers/acpi. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
