Original Post: http://lkml.kernel.org/r/20121214184207.6E00DDEC@kernel.stglabs.ibm.com Again, trying to come up with some common themes of the stuff in the kernel hacking menu... There are quite a few options to tweak compilation in some way, or perform extra compile-time checks. Give them their own menu. The diff here looks a bit funny... makes it look like I'm moving debugfs even though I'm actually moving the options on either side of it.

Original posting: http://lkml.kernel.org/r/20121214184206.FC11422F@kernel.stglabs.ibm.com These runtime tests are great, except that there are a lot of them, and they are very rarely needed. Give them their own menu so that only the folks who need them will have to go looking for them. Note that there are some other runtime tests that are not in here, like for RCU or locking.

2013-07-04order memory debugging Kconfig optionsDave Hansen
Original posting: http://lkml.kernel.org/r/20121214184203.37E6C724@kernel.stglabs.ibm.com There are a *LOT* of memory debugging options. They are just scattered all over the "Kernel Hacking" menu. Sure, "memory debugging" is a very vague term and it's going to be hard to make absolute rules about what goes in here, but this has to be better than what we had before. This does, however, leave out the architecture-specific memory debugging options (like x86's DEBUG_SET_MODULE_RONX). There would need to be some substantial changes to move those in here. Kconfig can not easily mix arch-specific and generic options together: it really requires a file per-architecture, and I think having an arch/foo/Kconfig.debug-memory might be taking things a bit too far Signed-off-by: Dave Hansen <dave@linux.vnet.ibm.com> Signed-off-by: Dave Hansen <dave.hansen@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2013-07-04consolidate per-arch stack overflow debugging optionsDave Hansen
Original posting: http://lkml.kernel.org/r/20121214184202.F54094D9@kernel.stglabs.ibm.com Several architectures have similar stack debugging config options. They all pretty much do the same thing, some with slightly differing help text. This patch changes the architectures to instead enable a Kconfig boolean, and then use that boolean in the generic Kconfig.debug to present the actual menu option. This removes a bunch of duplication and adds consistency across arches. Signed-off-by: Dave Hansen <dave@linux.vnet.ibm.com> Reviewed-by: H.

In addition to the usual bug fixes and small updates, the main highlights are: - Support for transparent huge pages by Aneesh Kumar for 64-bit server processors.

It is no longer specific to pseries but is now usable by the new "powernv" platform as well (no hypervisor) by Gavin Shan. - I fixed some bugs in our math-emu instruction decoding and made it usable to emulate some optional FP instructions on processors with hard FP that lack them (such as fsqrt on Freescale embedded processors). - Support for Power8 "Event Based Branch" facility by Michael Ellerman. This facility allows what is basically "userspace interrupts" for performance monitor events. - A bunch of Transactional Memory vs. Signals bug fixes and HW breakpoint/watchpoint fixes by Michael Neuling.

2013-07-04posix-cpu-timers: don't account cpu timer after stopped thread runtime ↵KOSAKI Motohiro
accounting When tsk->signal->cputimer->running is 1, signal->cputimer (i.e. per process timer account) and tsk->sum_sched_runtime (i.e. per thread timer account) increase at the same pace because update_curr() increases both accounting. However, there is one exception. When thread exiting, __exit_signal() turns over task's sum_shced_runtime to sig->sum_sched_runtime, but it doesn't stop signal->cputimer accounting. This inconsistency makes POSIX timer wake up too early. This patch fixes it.

2013-07-04HID: wacom: Intuos4 battery charging changesPrzemo Firszt
Intuos4 WL is separately reporting power supply and battery charging status - now hid-wacom is using that information. Previously hid-wacom was wrongly treating "battery charging" bit as "power supply connected". Now it should report battery charging, battery discharging, battery full and power supply status. Intuos4 WL sends reports when is in use (obvious) and when unplugging power supply. If means that if the device is being charged, but it's not being used it will never report "battery full". The same problem happens after the device has been connected, but it's not in use - the battery/ac status will be incorrect.

2013-07-04ACPI / PM: Fix corner case in acpi_bus_update_power()Rafael J. Wysocki
The role of acpi_bus_update_power() is to update the given ACPI device object's power.state field to reflect the current physical state of the device (as inferred from the configuration of power resources and _PSC, if available). For this purpose it calls acpi_device_set_power() that should update the power resources' reference counters and set power.state as appropriate. However, that doesn't work if the "new" state is D1, D2 or D3hot and the the current value of power.state means D3cold, because in that case acpi_device_set_power() will refuse to transition the device from D3cold to non-D0. To address this problem, make acpi_bus_update_power() call acpi_power_transition() directly to update the power resources' reference counters and only use acpi_device_set_power() to put the device into D0 if the current physical state of it cannot be determined.

2013-07-04cpufreq: Fix serialization of frequency transitionsViresh Kumar
Commit 7c30ed ("cpufreq: make sure frequency transitions are serialized") interacts poorly with systems that have a single core freqency for all cores. On such systems we have a single policy for all cores with several CPUs. When we do a frequency transition the governor calls the pre and post change notifiers which causes cpufreq_notify_transition() per CPU. Since the policy is the same for all of them all CPUs after the first and the warnings added are generated by checking a per-policy flag the warnings will be triggered for all cores after the first. Fix this by allowing notifier to be called for n times. Where n is the number of cpus in policy->cpus.

2013-07-04ALSA: hda - Fix EAPD vmaster hook for AD1884 & coTakashi Iwai
ad1884_fixup_hp_eapd() tries to set the NID for controlling the speaker EAPD from the pin configuration. But the current code can't work expectedly since it sets spec->eapd_nid before calling the generic parser where the autocfg pins are set up. This patch changes the function to set spec->eapd_nid after the generic parser call while it sets vmaster hook unconditionally. The spec->eapd_nid check is moved in the hook function itself instead.
