Merge branch 'acpi-general'
* acpi-general: (38 commits) ACPI / thermal: _TMP and _CRT/_HOT/_PSV/_ACx dependency fix ACPI: drop unnecessary local variable from acpi_system_write_wakeup_device() ACPI: Fix logging when no pci_irq is allocated ACPI: Update Dock hotplug error messages ACPI: Update Container hotplug error messages ACPI: Update Memory hotplug error messages ACPI: Update CPU hotplug error messages ACPI: Add acpi_handle_<level>() interfaces ACPI: remove use of __devexit ACPI / PM: Add Sony Vaio VPCEB1S1E to nonvs blacklist. ACPI / battery: Correct battery capacity values on Thinkpads Revert "ACPI / x86: Add quirk for "CheckPoint P-20-00" to not use bridge _CRS_ info" ACPI: create _SUN sysfs file ACPI / memhotplug: bind the memory device when the driver is being loaded ACPI / memhotplug: don't allow to eject the memory device if it is being used ACPI / memhotplug: free memory device if acpi_memory_enable_device() failed ACPI / memhotplug: fix memory leak when memory device is unbound from acpi_memhotplug ACPI / memhotplug: deal with eject request in hotplug queue ACPI / memory-hotplug: add memory offline code to acpi_memory_device_remove() ACPI / memory-hotplug: call acpi_bus_trim() to remove memory device ...

Date: October 2012
|
||||
Contact: Yasuaki Ishimatsu <isimatu.yasuaki@jp.fujitsu.com>
|
||||
Description:
|
||||
The file contains a Slot-unique ID which provided by the _SUN
|
||||
method in the ACPI namespace. The value is written in Advanced
|
||||
Configuration and Power Interface Specification as follows:
|
||||
|
||||
"The _SUN value is required to be unique among the slots of
|
||||
the same type. It is also recommended that this number match
|
||||
the slot number printed on the physical slot whenever possible."
|
||||
|
||||
So reading the sysfs file, we can identify a physical position
|
||||
of the slot in the system.

are thus unaffected (tested with t42, t61, t500, x200, x300,
