2012-08-10ACPI / PM: Fix unused function warnings for CONFIG_PM_SLEEPRafael J. Wysocki
According to compiler warnings, several suspend/resume functions in ACPI drivers are not used for CONFIG_PM_SLEEP unset, so add #ifdefs to prevent them from being built in that case. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2012-07-01ACPI: Use struct dev_pm_ops for power management in the fan driverRafael J. Wysocki
Make the ACPI fan driver define its PM callbacks through a struct dev_pm_ops object rather than by using legacy PM hooks in struct acpi_device_ops. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2012-07-01ACPI / PM: Drop pm_message_t argument from device suspend callbackRafael J. Wysocki
None of the drivers implementing the ACPI device suspend callback uses the pm_message_t argument of it, so this argument may be dropped entirely from that callback. This will simplify switching the ACPI bus type to PM handling based on struct dev_pm_ops. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2011-07-16ACPI: constify ops structsVasiliy Kulikov
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.

2011-01-12ACPI / Fan: Rework the handling of power resourcesRafael J. Wysocki
Use the new function acpi_bus_update_power() for manipulating power resources used by ACPI fan devices, which allows them to be put into the right state during initialization and resume. Consequently, remove the flags.force_power_state field from struct acpi_device, which is not necessary any more. Signed-off-by: Rafael J.

2009-03-31proc 2/2: remove struct proc_dir_entry::ownerAlexey Dobriyan
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

2008-07-16ACPI: fix acpi fan state set errorYi Yang
Under /proc/acpi, there is a fan control interface, a user can set 0 or 3 to /proc/acpi/fan/*/state, 0 denotes D0 state, 3 denotes D3 state, but in current implementation, a user can set a fan to D1 state by any char excluding '1', '2' and '3'. For example: [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: off [root@localhost acpi]# echo "" > /proc/acpi/fan/C31B/state [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: on [root@localhost acpi]# echo "3" > /proc/acpi/fan/C31B/state [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: off [root@localhost acpi]# echo "xxxxx" > /proc/acpi/fan/C31B/state [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: on Obviously, such inputs as "" and "xxxxx" are invalid for fan state. This patch fixes this issue, it strictly limits fan state only to accept 0, 1, 2 and 3, any other inputs are invalid. Before applying this patch, the test result is: [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: off [root@localhost acpi]# echo "" > /proc/acpi/fan/C31B/state [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: on [root@localhost acpi]# echo "3" > /proc/acpi/fan/C31B/state [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: off [root@localhost acpi]# echo "xxxxx" > /proc/acpi/fan/C31B/state [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: on [root@localhost acpi]# echo "3" > /proc/acpi/fan/C31B/state [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: off [root@localhost acpi]# echo "3x" > /proc/acpi/fan/C31B/state [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: off [root@localhost acpi]# echo "-1x" > /proc/acpi/fan/C31B/state [root@localhost acpi]# cat /proc/acpi/fan/C31B/state status: on [root@localhost acpi]# After applying this patch, the test result is: [root@localhost ~]# cat /proc/acpi/fan/C31B/state status: off [root@localhost ~]# echo "" > /proc/acpi/fan/C31B/state -bash: echo: write error: Invalid argument [root@localhost ~]# cat /proc/acpi/fan/C31B/state status: off [root@localhost ~]# echo "3" > /proc/acpi/fan/C31B/state [root@localhost ~]# cat /proc/acpi/fan/C31B/state status: off [root@localhost ~]# echo "xxxxx" > /proc/acpi/fan/C31B/state -bash: echo: write error: Invalid argument [root@localhost ~]# cat /proc/acpi/fan/C31B/state status: off [root@localhost ~]# echo "-1x" > /proc/acpi/fan/C31B/state -bash: echo: write error: Invalid argument [root@localhost ~]# cat /proc/acpi/fan/C31B/state status: off [root@localhost ~]# echo "0" > //proc/acpi/fan/C31B/state [root@localhost ~]# cat /proc/acpi/fan/C31B/state status: on [root@localhost ~]# echo "4" > //proc/acpi/fan/C31B/state -bash: echo: write error: Invalid argument [root@localhost ~]# cat /proc/acpi/fan/C31B/state status: on [root@localhost ~]# echo "3" > //proc/acpi/fan/C31B/state [root@localhost ~]# cat /proc/acpi/fan/C31B/state status: off [root@localhost ~]# echo "0" > //proc/acpi/fan/C31B/state [root@localhost ~]# cat /proc/acpi/fan/C31B/state status: on [root@localhost ~]# echo "3x" > //proc/acpi/fan/C31B/state -bash: echo: write error: Invalid argument [root@localhost ~]# Signed-off-by: Yi Yang <yi.y.yang@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com> Acked-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
