- 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.
