This patch introduces a new way of checking for the cmov instruction. I use signal handling instead of reading /proc/cpuinfo.

Implement get_wchan - the algorithm is similar to x86. It starts with the stack pointer of the process in question and looks above that for addresses that are kernel text. The second one which isn't in the scheduler is the one that's returned. The first one is ignored because that will be UML's own context switching routine. Signed-off-by:

This patch contains varied fixes and improvements for some files under arch/um/os-Linux/, such as a typo fix in a perror message, a missing argument fix for a printf, some constifying for pointers and so on. [ jdike - made sigprocmask failure return -errno instead of -1 ] Signed-off-by:

init.h started breaking now for some reason. It turns out that there wasn't a definition of __used. Fixed this by copying the relevant stuff from compiler.h in the userspace case, and including compiler.h in the kernel case. [xiyou.wangcong@gmail.com: added definition of __section] Signed-off-by:

An extra error handling label is needed for the case where the ioremap has succeeded. The problem was detected using the following semantic match (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T,T1,T2; identifier E; statement S; expression x1,x2; constant C; int ret; @@ T E; ... * E = ioremap(...); if (E == NULL) S ... when != iounmap(E) when != if (E != NULL) { ... iounmap(E); ...} when != x1 = (T1)E if (...) { ... when != iounmap(E) when != if (E != NULL) { ... iounmap(E); ...} when != x2 = (T2)E ( * return; | * return C; | * return ret; ) } // </smpl> Signed-off-by:

Improve including of architecture dependent Kconfig files. - Always include the architecture dependent Kconfig files. - Wrap architecture dependent Kconfig files inside an appropriate "if ETRAX_ARCH_Vxx" block. This makes it possible to run the configuration even without the arch links, which are created later in the build process. Signed-off-by:

The cc-cross-prefix is new and developed on request from Geert Uytterhoeven. With cc-cross-prefix it is now much easier to have a few default cross compile prefixes and defaulting to none - if none of them were present. ARCH maintainers are expected to pick up this feature soon. Signed-off-by:

Modify the b43 driver to avoid deadlocking suspend and resume, which happens as a result of attempting to unregister device objects locked by the PM core during suspend/resume cycles. Also, make it use a suspend-safe method of unregistering device object in the resume error path. Signed-off-by:

The following patch is a generalization of the latency.c implementation done by Arjan last year. It provides infrastructure for more than one parameter, and exposes a user mode interface for processes to register pm_qos expectations of processes. This interface provides a kernel and user mode interface for registering performance expectations by drivers, subsystems and user space applications on one of the parameters. Currently we have {cpu_dma_latency, network_latency, network_throughput} as the initial set of pm_qos parameters. The infrastructure exposes multiple misc device nodes one per implemented parameter. The set of parameters implement is defined by pm_qos_power_init() and pm_qos_params.h. This is done because having the available parameters being runtime configurable or changeable from a driver was seen as too easy to abuse. For each parameter a list of performance requirements is maintained along with an aggregated target value. The aggregated target value is updated with changes to the requirement list or elements of the list. Typically the aggregated target value is simply the max or min of the requirement values held in the parameter list elements. >From kernel mode the use of this interface is simple: pm_qos_add_requirement(param_id, name, target_value): Will insert a named element in the list for that identified PM_QOS parameter with the target value. Upon change to this list the new target is recomputed and any registered notifiers are called only if the target value is now different. pm_qos_update_requirement(param_id, name, new_target_value): Will search the list identified by the param_id for the named list element and then update its target value, calling the notification tree if the aggregated target is changed. with that name is already registered. pm_qos_remove_requirement(param_id, name): Will search the identified list for the named element and remove it, after removal it will update the aggregate target and call the notification tree if the target was changed as a result of removing the named requirement. >From user mode: Only processes can register a pm_qos requirement. To provide for automatic cleanup for process the interface requires the process to register its parameter requirements in the following way: To register the default pm_qos target for the specific parameter, the process must open one of /dev/[cpu_dma_latency, network_latency, network_throughput] As long as the device node is held open that process has a registered requirement on the parameter. The name of the requirement is "process_<PID>" derived from the current->pid from within the open system call. To change the requested target value the process needs to write a s32 value to the open device node. This translates to a pm_qos_update_requirement call. To remove the user mode request for a target value simply close the device node.
