2008-10-23ACPI: hack around sysfs warning with link orderZhao Yakui
There exists the following warning message will appear after the following commit is merged. >commit f2e969acd6d5981e6b1272810002558650d0736e >Author: Zhao Yakui <yakui.zhao@intel.com> >Date: Mon Aug 11 14:57:50 2008 +0800 >ACPI: Add "acpi.power_nocheck=1" to disable power state check in power transition: >WARNING: at linux-2.6/fs/sysfs/dir.c:463 sysfs_add_one+0x33/0x39() >sysfs: duplicate filename 'acpi' can not be created >kobject_add_internal failed for acpi with -EEXIST, don't try to register things with the same name in the same directory In the above commit the "acpi.power_nocheck" module parameter is defined in drivers/acpi/power.c file. As several module parameters using the same ACPI prefix are defined in the different files(for example: power_nocheck is defined in drivers/acpi/power.c,debug_layer/debug_level are defined in drivers/acpi/debug.c) and there exists another module between them, the warning message will be printed when using the current generic param code. (In the function of param_sysfs_init). In fact when ACPI is selected, the drivers/acpi/power will also be compiled as built-in kernel.So this issue can be fixed by the following approach. workaround it by adjusting the module link order in drivers/acpi/Makefile. In such case the module parameter using the same prefix(ACPI) are put together in the param data section. Of course the better solution is to fix it in generic param code related with sysfs.

2008-10-22ACPICA: New: Validation for predefined ACPI methods/objectsBob Moore
Validates predefined ACPI objects that appear in the namespace, at the time they are evaluated. The argument count and the type of the returned object are validated. The purpose of this validation is to detect problems with the BIOS-exposed predefined ACPI objects before the results are returned to the ACPI-related drivers.

2008-10-22PCI: update pci_create_slot() to take a 'hotplug' paramAlex Chiang
Slot detection drivers can co-exist with hotplug drivers. The names of the detected/claimed slots may be different depending on module load order. For legacy reasons, we need to allow hotplug drivers to override the slot name if a detection driver is loaded first (and they find the same slots). Creating and overriding slot names should be an atomic operation, otherwise you get a locking nightmare as various drivers race to call pci_create_slot(). pci_create_slot() is already serialized by grabbing the pci_bus_sem. We update the API and add a 'hotplug' param, which is: set if the caller is a hotplug driver NULL if the caller is a detection driver pci_create_slot() does not actually use the 'hotplug' parameter in this patch. A later patch will add the logic that uses it.

2008-10-22ACPI: Fix possible null ptr dereferencedonald.d.dugger@intel.com
Code in `pci_link.c' is calling the internal routine `acpi_ut_evaluate_object' which is dangerous given that it is passing a NULL pointer when it should be passing a pointer to a real object. The patch corrects the issue by having the code call the external routine `acpi_evaluate_object', which correctly handles a NULL pointer.
