device property: Avoid potential dereferences of invalid pointers

2016-04-27T21:40:02Z

Since fwnode may hold ERR_PTR(-ENODEV) or it may be NULL, the fwnode type checks is_of_node(), is_acpi_node() and is is_pset_node() need to consider it. Using IS_ERR_OR_NULL() to check it.

ACPICA: Remove unnecessary arguments to ACPI_INFO

2016-02-24T13:14:49Z

ACPICA commit 181f56605a771e0b91e24b0648d2565ca70bea20 This is used as a purely infomation message, without module name and line number information. Therefore, these arguments are not needed and they are unnecessary overhead. Arguments are removed. ACPICA BZ 872.

ACPI / sleep: move acpi_processor_sleep to sleep.c

2016-02-21T23:53:56Z

acpi_processor_sleep is neither related nor used by CPUIdle framework. It's used in system suspend/resume path as a syscore operation. It makes more sense to move it to acpi/sleep.c where all the S-state transition (a.k.a. Linux system suspend/hiberate) related code are present. Also make it depend on CONFIG_ACPI_SYSTEM_POWER_STATES_SUPPORT so that it's not compiled on architecture like ARM64 where S-states are not yet defined in ACPI.

ACPI / processor : add support for ACPI0010 processor container

2016-02-21T23:53:56Z

ACPI 6.0 adds support for optional processor container device which may contain child objects that are either processor devices or other processor containers. This allows representing hierarchical processor topologies. It is declared using the _HID of ACPI0010. It is an abstract container used to represent CPU topology and should not be used to hotplug purposes. If no matching handler is found for a device in acpi_scan_attach_handler, acpi_bus_attach does a default enumeration for those devices with valid HID in the acpi namespace. This patch adds a scan handler for these ACPI processor containers to avoid default that enumeration and ensures the platform devices are not created for them.

ACPI / CPPC: remove redundant mbox_send_message() declaration
