    Pull perf fixes from Thomas Gleixner:
     "A set of fixes for perf:
    
        - A set of commits which reduce the stack usage of various perf
          event handling functions which allocated large data structs on
          stack causing stack overflows in the worst case
    
        - Use the proper mechanism for detecting soft interrupts in the
          recursion protection
    
        - Make the resursion protection simpler and more robust
    
        - Simplify the scheduling of event groups to make the code more
          robust and prepare for fixing the issues vs. scheduling of
          exclusive event groups
    
        - Prevent event multiplexing and rotation for exclusive event groups
    
        - Correct the perf event attribute exclusive semantics to take
          pinned events, e.g. the PMU watchdog, into account
    
        - Make the anythread filtering conditional for Intel's generic PMU
          counters as it is not longer guaranteed to be supported on newer
          CPU...
