Pull x86 RAS update from Ingo Molnar: "Rework all config variables used throughout the MCA code and collect them together into a mca_config struct. This keeps them tightly and neatly packed together instead of spilled all over the place. Then, convert those which are used as booleans into real booleans and save some space.

ACPI / driver core: Introduce struct acpi_dev_node and related macros

2012-11-20T23:21:50+00:00

To avoid adding an ACPI handle pointer to struct device on architectures that don't use ACPI, or generally when CONFIG_ACPI is not set, in which cases that pointer is useless, define struct acpi_dev_node that will contain the handle pointer if CONFIG_ACPI is set and will be empty otherwise and use it to represent the ACPI device node field in struct device. In addition to that define macros for reading and setting the ACPI handle of a device that don't generate code when CONFIG_ACPI is unset. Modify the ACPI subsystem to use those macros instead of referring to the given device's ACPI handle directly. Signed-off-by: Rafael J.

driver core / ACPI: Move ACPI support to core device and driver types

2012-11-14T23:28:00+00:00

With ACPI 5 we are starting to see devices that don't natively support discovery but can be enumerated with the help of the ACPI namespace. Typically, these devices can be represented in the Linux device driver model as platform devices or some serial bus devices, like SPI or I2C devices. Since we want to re-use existing drivers for those devices, we need a way for drivers to specify the ACPI IDs of supported devices, so that they can be matched against device nodes in the ACPI namespace. To this end, it is sufficient to add a pointer to an array of supported ACPI device IDs, that can be provided by the driver, to struct device. Moreover, things like ACPI power management need to have access to the ACPI handle of each supported device, because that handle is used to invoke AML methods associated with the corresponding ACPI device node. The ACPI handles of devices are now stored in the archdata member structure of struct device whose definition depends on the architecture and includes the ACPI handle only on x86 and ia64. Since the pointer to an array of supported ACPI IDs is added to struct device_driver in an architecture-independent way, it is logical to move the ACPI handle from archdata to struct device itself at the same time. This also makes code more straightforward in some places and follows the example of Device Trees that have a poiter to struct device_node in there too. This changeset is based on Mika Westerberg's work. Signed-off-by: Mika Westerberg Acked-by: Greg Kroah-Hartman Acked-by: H. Peter Anvin Acked-by: Tony Luck Signed-off-by: Rafael J. Wysocki

drivers/base: Add a DEVICE_BOOL_ATTR macro

Pull power management updates from Rafael J Wysocki: - Improved system suspend/resume and runtime PM handling for the SH TMU, CMT and MTU2 clock event devices (also used by ARM/shmobile). - Generic PM domains framework extensions related to cpuidle support and domain objects lookup using names. - ARM/shmobile power management updates including improved support for the SH7372's A4S power domain containing the CPU core. - cpufreq changes related to AMD CPUs support from Matthew Garrett, Andre Przywara and Borislav Petkov. - cpu0 cpufreq driver from Shawn Guo. - cpufreq governor fixes related to the relaxing of limit from Michal Pecio. - OMAP cpufreq updates from Axel Lin and Richard Zhao. - cpuidle ladder governor fixes related to the disabling of states from Carsten Emde and me. - Runtime PM core updates related to the interactions with the system suspend core from Alan Stern and Kevin Hilman. - Wakeup sources modification allowing more helper functions to be called from interrupt context from John Stultz and additional diagnostic code from Todd Poynor. - System suspend error code path fix from Feng Hong. Fixed up conflicts in cpufreq/powernow-k8 that stemmed from the workqueue fixes conflicting fairly badly with the removal of support for hardware P-state chips.

dev_dbg/dynamic_debug: Update to use printk_emit, optimize stack

2012-09-17T13:08:30+00:00

commit c4e00daaa9 ("driver-core: extend dev_printk() to pass structured data") changed __dev_printk and broke dynamic-debug's ability to control the dynamic prefix of dev_dbg(dev,..). commit af7f2158fd ("drivers-core: make structured logging play nice with dynamic-debug") made a minimal correction. The current dynamic debug code uses up to 3 recursion levels via %pV. This can consume quite a bit of stack. Directly call printk_emit to reduce the recursion depth. These changes include: dev_dbg: o Create and use function create_syslog_header to format the syslog header for printk_emit uses. o Call create_syslog_header and neaten __dev_printk o Make __dev_printk static not global o Remove include header declaration of __dev_printk o Remove now unused EXPORT_SYMBOL() of __dev_printk o Whitespace neatening dynamic_dev_dbg: o Remove KERN_DEBUG from dynamic_emit_prefix o Call create_syslog_header and printk_emit o Whitespace neatening Signed-off-by: Joe Perches Acked-by: David S.
