Will Deacon e734568b67 oprofile: perf: use NR_CPUS instead or nr_cpumask_bits for static array
The OProfile perf backend uses a static array to keep track of the
perf events on the system. When compiling with CONFIG_CPUMASK_OFFSTACK=y
&& SMP, nr_cpumask_bits is not a compile-time constant and the build
will fail with:

oprofile_perf.c:28: error: variably modified 'perf_events' at file scope

This patch uses NR_CPUs instead of nr_cpumask_bits for the array
initialisation. If this causes space problems in the future, we can
always move to dynamic allocation for the events array.
