* MIPS: MT: Fix build error iFPU affinity codeRalf Baechle2010-10-251-1/+1
| | | | | | | | | | | | Commit b0ae19811375 ("security: remove unused parameter from security_task_setscheduler()") broke the build of arch/mips/kernel/mips-mt-fpaff.c. The function arguments were unnecessary, not the semicolon ...

* security: remove unused parameter from security_task_setscheduler()KOSAKI Motohiro2010-10-211-1/+1
| | | | | | | | | | | | | | All security modules shouldn't change sched_param parameter of security_task_setscheduler(). This is not only meaningless, but also make a harmful result if caller pass a static variable. This patch remove policy and sched_param parameter from security_task_setscheduler() becuase none of security module is using it.

* CRED: Wrap task credential accesses in the MIPS archDavid Howells2008-11-141-2/+3
| | | | | | | | | | | | | | | | | | Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.

| | | | | | | | | | | | There are some places left in mips, that lookup task in initial namespace, while the code doing so gets the pid from the user space and thus must treat it as virtual.

* cpu-hotplug: replace lock_cpu_hotplug() with get_online_cpus()Gautham R Shenoy2008-01-251-5/+5
| | | | | | | | | | | | | | | | | Replace all lock_cpu_hotplug/unlock_cpu_hotplug from the kernel and use get_online_cpus and put_online_cpus instead as it highlights the refcount semantics in these operations. The new API guarantees protection against the cpu-hotplug operation, but it doesn't guarantee serialized access to any of the local data structures. Hence the changes needs to be reviewed. In case of pseries_add_processor/pseries_remove_processor, use cpu_maps_update_begin()/cpu_maps_update_done() as we're modifying the cpu_present_map there.
