[PATCH 4/7] ARM: oprofile: Move non-ARM code into separate init/exit

[Matt Fleming <matt@console-pimps.org>]

In preparation for moving the majority of this oprofile code into an
architecture-neutral place separate the architecture-independent code
into oprofile_perf_init() and oprofile_perf_exit().
