2008-03-04Kprobes: move kprobe examples to samples/Ananth N Mavinakayanahalli
Move kprobes examples from Documentation/kprobes.txt to under samples/. Patch originally by Randy Dunlap. o Updated the patch to apply on 2.6.25-rc3 o Modified examples code to build on multiple architectures. Currently, the kprobe and jprobe examples code works for x86 and powerpc o Cleaned up unneeded #includes o Cleaned up Kconfig per Sam Ravnborg's suggestions to fix build break on archs that don't have kretprobes o Implemented suggestions by Mathieu Desnoyers on CONFIG_KRETPROBES o Included Andrew Morton's cleanup based on x86-git o Modified kretprobe_example to act as a arch-agnostic module to determine routine execution times: Use 'modprobe kretprobe_example func=<func_name>' to determine execution time of func_name in nanoseconds.

2008-03-04gpio: <linux/gpio.h> and "no GPIO support here" stubsDavid Brownell
Add a <linux/gpio.h> defining fail/warn stubs for GPIO calls on platforms that don't support the GPIO programming interface. That includes the arch-specific implementation glue otherwise. This facilitates a new model for GPIO usage: drivers that can use GPIOs if they're available, but don't require them. One example of such a driver is NAND driver for various FreeScale chips. On platforms update with GPIO support, they can be used instead of a worst-case delay to verify that the BUSY signal is off. (Also includes a couple minor unrelated doc updates.)

2008-03-04PCI: Add DECLARE_PCI_DEVICE_TABLE macroJonas Bonn
The definitions of struct pci_device_id arrays should generally follow the same pattern across the entire kernel. This macro defines this array as const and puts it into the __devinitconst section. There are currently many definitions scattered about the kernel that omit the __devinitdata modifier despite the documentation stating that it should always be there. These definitions really also should have been const, which wasn't possible before but has become so with the addition of the __devinitconst attribute. Furthermore, there are definitions that use "const" and __devinitdata, which is explicitly wrong but the compiler doesn't catch section mismatches if there's only one such one case in the module (which is often the case). Adding the __devinitconst modifier where there was nothing before buys us memory. Adding the const modifier gives the compiler a chance to do its thing. Changing __devinitdata to __devinitconst where it was wrong actually fixes some compiler errors in older (mid-release) kernels that were patched over by "removing" the section attribute altogether (which wastes memory). This macro makes it pretty difficult to get this definition wrong in the future... Signed-off-by: Jonas Bonn <jonas@southpole.se> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-02-23documentation: atomic_add_unless() doesn't imply mb() on failureOleg Nesterov
(sorry for being offtpoic, but while experts are here...) A "typical" implementation of atomic_add_unless() can return 0 immediately after the first atomic_read() (before doing cmpxchg). In that case it doesn't provide any barrier semantics. See include/asm-ia64/atomic.h as an example. We should either change the implementation, or fix the docs.

2008-02-23PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki
During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.

2008-02-16ACPI: thinkpad-acpi: add tablet-mode reportingHenrique de Moraes Holschuh
A quick study of the 0x5009/0x500A HKEY event on the X61t DSDT revealed the existence of the EC HTAB register (EC 0x0f, bit 7), and a compare with the X41t DSDT shows that HKEY.MHKG can be used to verify if the ThinkPad is tablet-capable (MHKG present), and in tablet mode (bit 3 of MHKG return is set). Add an attribute to report this information, "hotkey_tablet_mode". This attribute has poll()/select() support, and can be used along with EV_SW SW_TABLET_MODE to hook userspace to tablet events.
