treewide: Convert del_timer*() to timer_shutdown*()
Due to several bugs caused by timers being re-armed after they are shutdown and just before they are freed, a new state of timers was added called "shutdown". After a timer is set to this state, then it can no longer be re-armed.
The following script was run to find all the trivial locations where del_timer() or del_timer_sync() is called in the same function that the object holding the timer is freed. It also ignores any locations where the timer->function is modified between the del_timer*() and the free(), as that is not considered a "trivial" case.
This was created by using a coccinelle script and the following commands:
$ cat timer.cocci @@ expression ptr, slab; identifier timer, rfield; @@ ( - del_timer(&ptr->timer); + timer_shutdown(&ptr->timer); | - del_timer_sync(&ptr->timer); + timer_shutdown_sync(&ptr->timer); ) ... when strict when != ptr->timer ( kfree_rcu(ptr, rfield); | kmem_cache_free(slab, ptr); | kfree(ptr); )
$ spatch timer.cocci . > /tmp/t.patch $ patch -p1 < /tmp/t.patch

kernel.h: split out panic and oops helpers
kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out panic and oops helpers.
There are several purposes of doing this: - dropping dependency in bug.h - dropping a loop by moving out panic_notifier.h - unload kernel.h from something which has its own domain
At the same time convert users tree-wide to use new headers, although for the time being include new header back to kernel.h to avoid twisted indirected includes for existing users.

The trigger core learned error handling for the activate callback and can handle device attributes now. This allows simplifying the driver considerably. Note that .deactivate() is only called when .activate() succeeded, so the check for .activated can go away in .deactivate().
Also make use of module_led_trigger() and the accessor function to get and set trigger_data.

leds: ledtrig-activity: Add a system activity LED trigger
The "activity" trigger was inspired by the heartbeat one, but aims at providing instant indication of the immediate CPU usage. Under idle condition, it flashes 10ms every second. At 100% usage, it flashes 90ms every 100ms. The blinking frequency increases from 1 to 10 Hz until either the load is high enough to saturate one CPU core or 50% load is reached on a single-core system. Then past this point only the duty cycle increases from 10 to 90%.
This results in a very visible activity reporting allowing one to immediately tell whether a machine is under load or not, making it quite suitable to be used in clusters.

leds: activity trigger: simplifications from core changes The trigger core learned error handling for the activate callback and can handle device attributes now. This allows simplifying the driver considerably. Note that .deactivate() is only called when .activate() succeeded, so the check for .activated can go away in .deactivate(). Also make use of module_led_trigger() and the accessor function to get and set trigger_data.

leds: ledtrig-activity: Add a system activity LED trigger The "activity" trigger was inspired by the heartbeat one, but aims at providing instant indication of the immediate CPU usage. Under idle condition, it flashes 10ms every second. At 100% usage, it flashes 90ms every 100ms. The blinking frequency increases from 1 to 10 Hz until either the load is high enough to saturate one CPU core or 50% load is reached on a single-core system. Then past this point only the duty cycle increases from 10 to 90%. This results in a very visible activity reporting allowing one to immediately tell whether a machine is under load or not, making it quite suitable to be used in clusters.
