The _WAK global ACPI control method has to be called with the argument representing the sleep state being exited. Make it happen.

2008-02-14ACPI, cpuidle: Clarify C-state description in sysfsVenkatesh Pallipadi
Add a new sysfs entry under cpuidle states. desc - can be used by driver to communicate to userspace any specific information about the state. This helps in identifying the exact hardware C-states behind the ACPI C-state definition. Idea is to export this through powertop, which will help to map the C-state reported by powertop to actual hardware C-state.

2008-02-13ACPI: fix suspend regression due to idle updateVenkatesh Pallipadi
Earlier patch (bc71bec91f9875ef825d12104acf3bf4ca215fa4) broke suspend resume on many laptops. The problem was reported by Carlos R. Mafra and Calvin Walton, who bisected the issue to above patch. The problem was because, C2 and C3 code were calling acpi_idle_enter_c1 directly, with C2 or C3 as state parameter, while suspend/resume was in progress. The patch bc71bec started making use of that state information, assuming that it would always be referring to C1 state. This caused the problem with suspend-resume as we ended up using C2/C3 state indirectly. Fix this by adding acpi_idle_suspend check in enter_c1.

2008-02-13acpi: fix acpi_os_read_pci_configuration() misuse of raw_pci_read()Linus Torvalds
The raw_pci_read() interface (as the raw_pci_ops->read() before it) unconditionally fills in a 32-bit integer return value regardless of the size of the operation requested. So claiming to take a "void *" is wrong, as is passing in a pointer to just a byte variable. Noticed by pageexec when enabling -fstack-protector (which needs other patches too to actually work, but that's a separate issue).

2008-02-11WMI: initialize wmi_blocks.list even if ACPI is disabledLinus Torvalds
Even if we don't want to register the WMI driver, we should initialize the wmi_blocks list to be empty, since we don't want the wmi helper functions to oops just because that basic list has not even been set up. With this, "find_guid()" will happily return "not found" rather than oopsing all over the place, and the callers will then just automatically return false or AE_NOT_FOUND as appropriate.

2008-02-10Change pci_raw_ops to pci_raw_read/writeMatthew Wilcox
We want to allow different implementations of pci_raw_ops for standard and extended config space on x86. Rather than clutter generic code with knowledge of this, we make pci_raw_ops private to x86 and use it to implement the new raw interface -- raw_pci_read() and raw_pci_write().

2008-02-09x86: fix sparse warnings in acpi/bus.cHarvey Harrison
Add function definition and extern variables to asm-x86/acpi.h. All of these are used in bus.c in ifdef(CONFIG_X86) sections, so are only added to the x86 include headers. boot.c already includes acpi.h so no changes are needed there. Fixes the following: arch/x86/kernel/acpi/boot.c:83:4: warning: symbol 'acpi_sci_flags' was not declared. Should it be static? arch/x86/kernel/acpi/boot.c:84:5: warning: symbol 'acpi_sci_override_gsi' was not declared.

2008-02-07ACPI: video: Ignore ACPI video devices that aren't present in hardwareMatthew Garrett
Vendors often ship machines with a choice of integrated or discrete graphics, and use the same DSDT for both. As a result, the ACPI video module will locate devices that may not exist on this specific platform. Attempt to determine whether the device exists or not, and abort the device creation if it do not exist.

Introduce new module parameter for brightness control. "brightness_switch_enabled" is set by default which means nothing changes upon brightness switch events. When "brightness_switch_enabled" is cleared via "echo 0 > /sys/module/video/parameters/brightness_switch_enabled", ACPI will not try to change the brightness level any more. Either X will take charge of this or users can change the brightness level by poking /sys/class/backlight/acpi_videoX/...
