Linus Torvalds 64b609d6a6 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
    CPUs. Check the corresponding CPUID leaf to make sure.
 
  - Fixup a duplicate initialization in an array which was probably cause by
    the usual copy & paste - forgot to edit mishap.
