Perf events updates for this cycle:
- Platform PMU driver updates:
- x86 Intel uncore driver updates for Skylake (SNR) and Icelake (ICX) servers
- Fix RDPMC support
- Fix [extended-]PEBS-via-PT support
- Fix Sapphire Rapids event constraints
- Fix :ppp support on Sapphire Rapids
- Fix fixed counter sanity check on Alder Lake & X86_FEATURE_HYBRID_CPU
- Other heterogenous-PMU fixes
- Kprobes:
- Remove the unused and misguided kprobe::fault_handler callbacks.
- Warn about kprobes taking a page fault.
- Fix the 'nmissed' stat counter.
