ring_buffer: map to cpu not page
My original patch had a compile bug when NUMA was configured. I
referenced cpu when it should have been cpu_buffer->cpu.
Ingo quickly fixed this bug by replacing cpu with 'i' because that
was the loop counter. Unfortunately, the 'i' was the counter of
pages, not CPUs. This caused a crash when the number of pages allocated
for the buffers exceeded the number of pages, which would usually
be the case.
