MIPS: MT: Fix build error iFPU affinity code

2010-10-25T15:12:27+00:00

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()

2010-10-20T23:12:44+00:00

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.

MIPS: Use set_cpus_allowed_ptr

2010-05-21T20:31:14+00:00

From: Julia Lawall 

Use set_cpus_allowed_ptr rather than set_cpus_allowed.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// 
@@
expression E1,E2;
@@

- set_cpus_allowed(E1, cpumask_of_cpu(E2))
+ set_cpus_allowed_ptr(E1, cpumask_of(E2))

- set_cpus_allowed(E, I)
+ set_cpus_allowed_ptr(E, &I)

CRED: Wrap task credential accesses in the MIPS arch

2008-11-13T23:38:37+00:00

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.

[MIPS] Use find_task_by_vpid in system calls

2008-02-19T17:01:30+00:00

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()

2008-01-25T20:08:02+00:00

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.
