* uml: const and other tidyingWANG Cong2008-02-057-13/+12
| | | | | | | | | | | This patch also does some improvements for uml code. Improvements include dropping unnecessary cast, killing some unnecessary code and still some constifying for pointers etc..

* uml: further bugs.c tidyingJeff Dike2008-02-054-36/+24
| | | | | | | | | | | | | | | | | | | | | | bugs.c, for both i386 and x86_64, can undergo further cleaning - The i386 arch_check_bugs only does one thing, so we might as well inline the cmov checking. The i386 includes can be trimmed down a bit. arch_init_thread wasn't used, so it is deleted. The panics in arch_handle_signal are turned into printks because the process is about to get segfaulted anyway, so something is dying no matter what happens here. Also, the return value was always the same, so it contained no information, so it can be void instead. The name is changed to arch_examine_signal because it doesn't handle anything. The caller of arch_handle_signal, relay_signal, does things in a different order. The kernel-mode signal check is now first, which puts everything else together, making things a bit clearer conceptually.

| | | | | | | | | | | | 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.

* pm qos infrastructure and interfaceMark Gross2008-02-057-7/+520
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* nommu: add new vmalloc_user() and remap_vmalloc_range() interfaces.Paul Mundt2008-02-051-1/+44
| | | | | | | | | | | | | | | | | | | | | | This builds on top of the earlier vmalloc_32_user() work introduced by b50731732f926d6c49fd0724616a7344c31cd5cf, as we now have places in the nommu allmodconfig that hit up against these missing APIs. As vmalloc_32_user() is already implemented, this is moved over to vmalloc_user() and simply made a wrapper. As all current nommu platforms are 32-bit addressable, there's no special casing we have to do for ZONE_DMA and things of that nature as per GFP_VMALLOC32. remap_vmalloc_range() needs to check VM_USERMAP in order to figure out whether we permit the remap or not, which means that we also have to rework the vmalloc_user() code to grovel for the VMA and set the flag.

| | | | | | | | | | | | | The function is question gets the pid from sysctl table, so this one is a virtual pid, i.e. the pid of a task as it is seen from inside a namespace.
