   # HEAD: f8c857238a392f21d5726d07966f6061007c8d4f uprobes: Remove too strict lockdep_assert() condition in hprobe_expire()

Miscellaneous perf events fixes and a minor HW enablement change:

 - Fix missing RCU protection in perf_iterate_ctx()

 - Fix pmu_ctx_list ordering bug

 - Reject the zero page in uprobes

 - Fix a family of bugs related to low frequency sampling

 - Add Intel Arrow Lake U CPUs to the generic Arrow Lake
   RAPL support table

 - Fix a lockdep-assert false positive in uretprobes

 Thanks,

	Ingo
