2007-10-12Driver core: change add_uevent_var to use a structKay Sievers
This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

2007-10-10drivers/firmware: const-ify DMI API and internalsJeff Garzik
Three main sets of changes: 1) dmi_get_system_info() return value should have been marked const, since callers should not be changing that data. 2) const-ify DMI internals, since DMI firmware tables should, whenever possible, be marked const to ensure we never ever write to that data area. 3) const-ify DMI API, to enable marking tables const where possible in low-level drivers. And if we're really lucky, this might enable some additional optimizations on the part of the compiler. The bulk of the changes are #2 and #3, which are interrelated. #1 could have been a separate patch, but it was so small compared to the others, it was easier to roll it into this changeset.

2007-07-20Input: appletouch - improve powersaving for Geyser3 devicesSoeren Sonnenburg
The appletouch geyser3 devices found in the Intel Macs (and possibly some later PPC ones?) send a constant stream of packets after the first touch. This results in the kernel waking up around once every couple of milliseconds to process them, making it almost impossible to spend any significant amount of time in C3 state on a dynamic HZ kernel. Sending the mode initialization code makes the device shut up until it's touched again. This patch does so after receiving 10 packets with no interesting content.

On some boxes that don't have PS/2 mice connected at startup BIOS completely disables AUX port and attempts to access it result in hosed keyboard. Historically we do not trust ACPI/PNP data on i386 and try to poke AUX port even if we did not find an active PNP node for it. However in cases when BIOS writers got KBD port properly described we can assume that they did the right thing for AUX port as well. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2007-07-18Input: ads7846 - re-check pendown status before reporting eventsSemih Hazar
Pendown status from the PENIRQ pin is currently read only at the beginning of a sample set. If the pen is lifted just after sampling has began then sampled values become wrong. This patch adds an optional platform penirq_recheck_delay attribute. If non-zero, samples are only reported to the input subsystem if PENIRQ is still active that long after the samples taken.

2007-07-18Input: ads7846 - introduce sample settling delaySemih Hazar
The ads7846 driver has support for filtering, but when the chip gets deselected between samples this causes noise. This patch adds support for an optional settling delay time, so that two consecutive samples will be taken with the specified delay time apart. This ensures that the chip won't be deselected, so the noise won't appear. Filtering can still be done, but will have less work to do since each time a new sample is taken the same delay applies.

2007-07-18Input: xpad - add support for leds on xbox 360 padJan Kratochvil
Export LEDs on Xbox360 pad via led subsystem as a single device in /sys/class/leds/xpad[0-9]+. Xbox360 pad has four leds, which form a circle. Unfortunately the leds can't be controlled independently and can only display a predefined set of patterns (for example one is turned on wile others are off or a rotating pattern - 1-2-3-4). To activate a pattern one needs to send a specific command to the device (see http://www.free60.org/wiki/Gamepad). Led subsystem allows us to set brightness, but there is nothing like brightness on this device. So brightness is actually interpreted as the command (only values between 0 and 14 are accepted).

2007-07-17Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki
Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

2007-07-11sysfs: kill unnecessary attribute->ownerTejun Heo
sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded.
