ACPI: add dynamic_debug support 2014-07-01T03:11:58+00:00 Bjørn Mork bjorn@mork.no 2014-05-22T10:47:47+00:00 2c9b8a2ba1b6ccc9ef52b79e0312bae276b3c705 commit 45fef5b88d1f2f47ecdefae6354372d440ca5c84 upstream. Commit 1a699476e258 ("ACPI / hotplug / PCI: Hotplug notifications from acpi_bus_notify()") added debug messages for a few common events. These debug messages are unconditionally enabled if CONFIG_DYNAMIC_DEBUG is defined, contrary to the documented meaning, making the ACPI system spew lots of unwanted noise on any kernel with dynamic debugging. The bug was introduced by commit fbfddae69657 ("ACPI: Add acpi_handle_<level>() interfaces"), which added the CONFIG_DYNAMIC_DEBUG dependency without respecting its meaning.

Do not poke into device internals in acpi_processor_add() and touch "struct device { .offline }" attribute, since for CPUs onlined at boot it's set by: topology_init() -> arch_register_cpu() -> register_cpu() before ACPI device tree is parsed, and for hotplugged CPUs it's set when userspace onlines CPU via sysfs.
