Ben changed the cgroup API in commit f780bdb7c1c (cgroups: add
per-thread subsystem callbacks) in an incompatible way, but
forgot to convert the perf cgroup bits.

Avoid compile warnings and runtime splats and convert perf too ;-)

Vince noticed that unless we mmap() a buffer, SIGIO gets lost. So
explicitly push the wakeup (including signals) when requested.

Fix a few inconsistent style bits that were added over the past few
months.

As part of the events sybsystem unification, relocate hw_breakpoint.c
into its new destination.

mv kernel/perf_event.c -> kernel/events/core.c. From there, all further
sensible splitting can happen. The idea is that due to perf_event.c
becoming pretty sizable and with the advent of the marriage with ftrace,
splitting functionality into its logical parts should help speeding up
the unification and to manage the complexity of the subsystem.
