perf cgroup per-task attaching

Just FYI:

I'm getting

kernel/events/core.c:7445: warning: initialization from incompatible pointer type

when building -rc1 with CONFIG_CGROUP_PERF enabled. AFAICT, this is
due to the fact that f780bdb7c1c73009cb57adcf99ef50027d80bf3c dropped
the threadgroup arg from cgroup_subsys->attach in favour of per-thread
callbacks.

perf_cgroup_attach() actually does reschedule the task context after
the cgroup changes so the perf cgroup code would need some non-trivial
adjusting to the new APIs.
