ACPI sysfs.c strlen fix

2012-07-16T16:04:07Z

commit 9f132652d94c96476b0b0a8caf0c10e96ab10fa8 upstream. Current code is ignoring the last character of "enable" and "disable" in comparisons. https://bugzilla.kernel.org/show_bug.cgi?id=33732 Signed-off-by: Len Brown Signed-off-by: Greg Kroah-Hartman

ACPI: Export FADT pm_profile integer value to userspace

2011-11-07T01:48:42Z

There are a lot userspace approaches to detect the usage of the platform (laptop, workstation, server, ...) and adjust kernel tunables accordingly (io/process scheduler, power management, ...). These approaches need constant maintaining and are ugly to implement (detect PCMCIA controller -> laptop, does not work on recent systems anymore, ...) On ACPI systems there is an easy and reliable way (if implemented in BIOS and most recent platforms have this value set). -> export it to userspace.

ACPI: constify ops structs

2011-07-16T22:36:17Z

Structs battery_file, acpi_dock_ops, file_operations, thermal_cooling_device_ops, thermal_zone_device_ops, kernel_param_ops are not changed in runtime. It is safe to make them const. register_hotplug_dock_device() was altered to take const "ops" argument to respect acpi_dock_ops' const notion.

ACPI: Cleanup custom_method debug stuff

2011-05-29T05:50:04Z

- Move param aml_debug_output to other params into sysfs.c - Split acpi_debugfs_init to prepare custom_method to be an own .config option and driver. Signed-off-by: Thomas Renninger Acked-by: Rafael J. Wysocki Acked-by: rui.zhang@intel.com Signed-off-by: Len Brown

ACPICA: Global event handler

2011-01-12T09:27:00Z

The global event handler is called whenever a general purpose or fixed ACPI event occurs. Also update Linux OSL to collect events counter with global event handler. Signed-off-by: Lin Ming Signed-off-by: Len Brown

ACPI: fix build warnings resulting from merge window conflict

2010-09-29T01:38:01Z

drivers/acpi/sysfs.c:154: warning: passing argument 1 of '__check_old_set_param' from incompatible pointer type include/linux/moduleparam.h:165: note: expected 'int (*)(const char *, struct kernel_param *)' but argument is of type 'int (*)(const char *, const struct kernel_param *)' Introduced by commit 1c8fce27e275fd7c6b75bc6455745f02d3903ee6 ("ACPI: introduce drivers/acpi/sysfs.c") interacting with commit 9bbb9e5a33109b2832e2e63dcc7a132924ab374b ("param: use ops in struct kernel_param, rather than get and set fns directly"). Use module_param_cb instead of the obsoleted module_param_call to fix a build warning. Signed-off-by: Zhang Rui Signed-off-by: Len Brown
