The task->time_in_state pointer is written to at task creation
and exiting, protection is needed for concurrent reads e.g. during
sysfs accesses.  Added spin lock such that the task's time_in_state
pointer used is set to either allocated memory or null.

cpufreq stats does not correctly supports multiple cpus per profile.
For instance Marlin/Sailfish per cpu stats struct does not get created
for all cpus (only one per policy).  This change does not provide full
support for multiple cpus per profile but allows stats creation per
cpu to allow b/34133340 to be completed.

[ Upstream commit 43239cbe79fc369f5d2160bd7f69e28b5c50a58c ]

Feedback has shown that WRITE_ONCE(x, val) is easier to use than
ASSIGN_ONCE(val,x).
There are no in-tree users yet, so lets change it for 3.19.

ACCESS_ONCE does not work reliably on non-scalar types. For
example gcc 4.6 and 4.7 might remove the volatile tag for such
accesses during the SRA (scalar replacement of aggregates) step
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58145)

Let's provide READ_ONCE/ASSIGN_ONCE that will do all accesses via
scalar types as suggested by Linus Torvalds. Accesses larger than
the machines word size cannot be guaranteed to be atomic. These
macros will use memcpy and emit a build warning.
