[patch 00/11] x86/perf/intel_uncore: Cleanup and enhancements

[Thomas Gleixner]

While working on the hotplug rewrite I stumbled over the uncore drivers. The
intel_uncore driver particular is a complete trainwreck:

 - Lacks any form of proper error handling. Most errors are simply ignored.

 - Leaks memory and hardware state in case of failures

 - Tries to mimick a per cpu machinery for a facility which is strictly per
   package. That is implemented with convoluted alloc/free dancing during cpu
   hotplug with magic loops over the online cpus

The series cleans up the mess

 - Implement proper error handling

 - Switch to a per package storage model

 - Make MSR and PCI independent as far as it goes

 - Allow it to build as a module

Thanks,
