Subject: [patch V2 00/28] x86/perf/intel/uncore|rapl: Fix error handling and
 sanitize pmu management

This series addresses the following issues:

 - Add proper error handling to uncore and rapl drivers

 - Get rid of the pseudo per cpuness of these drivers and do a proper per
   package storage

 - Allow them to be modular

In order to do proper per package storage I added a facility which sanity
checks the physical package id of the processors which is supplied by bios and
does a logical package id translation. That allows drivers to do allocations
for the maximum number of possible packages independent of possible BIOS
creativity.

Changes vs. V1:

  - Add logical package management

  - Drop the exit_box callbacks for modern processors. This needs to be
    revisited on a case by case basis.

  - Fixup and convert the rapl driver as well

Thanks,

	tglx
