oprofile: introduce module_param oprofile.cpu_type
This patch removes module_param oprofile.force_arch_perfmon and introduces oprofile.cpu_type=archperfmon instead. This new parameter can be reused for other models and architectures. Currently only archperfmon is supported. Cc: Andi Kleen <ak@linux.intel.com> Signed-off-by: Robert Richter <robert.richter@amd.com>
