Cover letter [PATCH 0/6][v4]: perf: Make POWER7 events available in sysfs

[PATCH 0/6][v4]: perf: Make POWER7 events available in sysfs

Make the generic and some POWER7-specific perf events available in sysfs. These changes mainly extend similar functionality implemented in x86 to work on POWER architecture as well.

Thanks to input from Stephane Eranian, Robert Richter, Peter Ziljstra and Jiri Olsa.

Changelog[v4]:
[Jiri Olsa]: Document that multiple event= like terms can be specified in the 'events' file.
[Jiri Olsa]: Remove the documentation for the 'config format' file as it is already documented in 'Documentation/ABI/testing/' [Jiri Olsa]: Move the ABI documentaion from 'stable/' to 'testing/'.

Changelog[v3]:
[Jiri Olsa]: No need to define EVENT_ID, PMU_EVENT_PTR() if used only once
[Greg KH]: Document the new sysfs interfaces in Documenation/ABI

Changelog[v2]:
[Jiri Olsa] Use PMU_FORMAT_ATTR() rather than duplicating code.
