[PATCH] x86-64: Some cleanup and optimization to the processor data area.

2005-09-12T17:49:58Z

- Remove unused irqrsp field - Remove pda->me - Optimize set_softirq_pending slightly Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds

[PATCH] cpuset semaphore depth check optimize

2005-09-12T16:16:27Z

Optimize the deadlock avoidance check on the global cpuset semaphore cpuset_sem. Instead of adding a depth counter to the task struct of each task, rather just two words are enough, one to store the depth and the other the current cpuset_sem holder. Thanks to Nikita Danilov for the idea. Signed-off-by: Paul Jackson [ We may want to change this further, but at least it's now a totally internal decision to the cpusets code ] Signed-off-by: Linus Torvalds

Mark ia64-specific MCA/INIT scheduler hooks as dangerous

2005-09-12T14:59:21Z

..and only enable them for ia64. The functions are only valid when the whole system has been totally stopped and no scheduler activity is ongoing on any CPU, and interrupts are globally disabled. In other words, they aren't useful for anything else. So make sure that nobody can use them by mistake. Signed-off-by: Linus Torvalds

[PATCH] MCA/INIT: scheduler hooks

2005-09-11T21:01:30Z

Scheduler hooks to see/change which process is deemed to be on a cpu. Signed-off-by: Keith Owens Signed-off-by: Tony Luck

[PATCH] kernel: fix-up schedule_timeout() usage

2005-09-10T17:06:37Z

Use schedule_timeout_{,un}interruptible() instead of set_current_state()/schedule_timeout() to reduce kernel size. Signed-off-by: Nishanth Aravamudan Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] add schedule_timeout_{,un}interruptible() interfaces

2005-09-10T17:06:36Z

Add schedule_timeout_{,un}interruptible() interfaces so that schedule_timeout() callers don't have to worry about forgetting to add the set_current_state() call beforehand. Signed-off-by: Nishanth Aravamudan Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] kernel/acct: add kerneldoc

2005-09-10T17:06:26Z

for kernel/acct.c: - fix typos - add kerneldoc for non-static functions Signed-off-by: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] sched: allow the load to grow upto its cpu_power

2005-09-10T17:06:24Z

Don't pull tasks from a group if that would cause the group's total load to drop below its total cpu_power (ie. cause the group to start going idle). Signed-off-by: Suresh Siddha Signed-off-by: Nick Piggin Acked-by: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] sched: don't kick ALB in the presence of pinned task

2005-09-10T17:06:24Z

Jack Steiner brought this issue at my OLS talk. Take a scenario where two tasks are pinned to two HT threads in a physical package. Idle packages in the system will keep kicking migration_thread on the busy package with out any success. We will run into similar scenarios in the presence of CMP/NUMA.

[PATCH] sched: use cached variable in sys_sched_yield()

2005-09-10T17:06:23Z

In sys_sched_yield(), we cache current->array in the "array" variable, thus there's no need to dereference "current" again later. Signed-Off-By: Renaud Lienhart Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
