This patch restores default values for: /dev/oprofile/cpu_buffer_size /dev/oprofile/buffer_watershed /dev/oprofile/buffer_size when creating the oprofilefs: # opcontrol --deinit # opcontrol --init # cat /dev/oprofile/cpu_buffer_size 8192 # echo 5123 > /dev/oprofile/cpu_buffer_size # cat /dev/oprofile/cpu_buffer_size 5123 # opcontrol --deinit # opcontrol --init # cat /dev/oprofile/cpu_buffer_size 8192 # opcontrol --deinit This sets the values in a defined state. Before, there was no way to restore the defaults without rebooting the system or reloading the module. Signed-off-by: NRobert Richter <robert.richter@amd.com>

This patch introduces multiplexing support for the Oprofile kernel module. It basically adds a new function pointer in oprofile_operator allowing each architecture to supply its callback to switch between different sets of event when the timer expires. Userspace tools can modify the time slice through /dev/oprofile/time_slice. It also modifies the number of counters exposed to the userspace through /dev/oprofile. For example, the number of counters for AMD CPUs are changed to 32 and multiplexed in the sets of 4.

Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
