Merge tag 'perf-core-2023-06-27' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf events updates from Ingo Molnar:

 - Rework & fix the event forwarding logic by extending the core
   interface.

   This fixes AMD PMU events that have to be forwarded from the
   core PMU to the IBS PMU.

 - Add self-tests to test AMD IBS invocation via core PMU events

 - Clean up Intel FixCntrCtl MSR encoding & handling
