isdn: Convert obsolete cputime type to nsecs
...
Not sure if MISDN stats are ABI but it displays task cputime in cputime_t
raw value regardless of what type cputime_t wraps which could be either
jiffies, nsecs, usecs, or whatever random time unit. Plus it wrongly
assumes that cputime_t is long.
Given that this dump is broken anyway, lets just display the nanosec
value and stick with that.

sched/cputime: Convert task/group cputime to nsecs
...
Now that most cputime readers use the transition API which return the
task cputime in old style cputime_t, we can safely store the cputime in
nsecs. This will eventually make cputime statistics less opaque and more
granular. Back and forth convertions between cputime_t and nsecs in order
to deal with cputime_t random granularity won't be needed anymore.

sched/cputime: Introduce special task_cputime_t() API to return old-typed cputime
...
This API returns a task's cputime in cputime_t in order to ease the
conversion of cputime internals to use nsecs units instead. Blindly
converting all cputime readers to use this API now will later let us
convert more smoothly and step by step all these places to use the
new nsec based cputime.

sched/cputime: Convert kcpustat to nsecs
...
Kernel CPU stats are stored in cputime_t which is an architecture
defined type, and hence a bit opaque and requiring accessors and mutators
for any operation.
Converting them to nsecs simplifies the code and is one step toward
the removal of cputime_t in the core code.

tracing: Fix hwlat kthread migration
...
The hwlat tracer creates a kernel thread at start of the tracer. It is
pinned to a single CPU and will move to the next CPU after each period of
running. If the user modifies the migration thread's affinity, it will not
change after that happens.
The original code created the thread at the first instance it was called,
but later was changed to destroy the thread after the tracer was finished,
and would not be created until the next instance of the tracer was
established. The code that initialized the affinity was only called on the
initial instantiation of the tracer. After that, it was not initialized, and
the previous affinity did not match the current newly created one, making
it appear that the user modified the thread's affinity when it did not, and
the thread failed to migrate again.
