Subject: [GIT PULL] Performance events changes for v6.10

Linus,

Please pull the latest perf/core Git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-2024-05-13

   # HEAD: 854dd99b5ddc9d90e31e5f112462a5994dd31810 perf/bpf: Mark perf_event_set_bpf_handler() and perf_event_free_bpf_handler() as inline too

Perf events changes for v6.10:

 - Combine perf and BPF for fast evalution of HW breakpoint
   conditions.

 - Add LBR capture support outside of hardware events

 - Trigger IO signals for watermark_wakeup

 - Add RAPL support for Intel Arrow Lake and Lunar Lake

 - Optimize frequency-throttling

 - Miscellaneous cleanups & fixes.

 Thanks,

	Ingo

      perf/x86/amd: Ensure amd_pmu_core_disable_all() is always inlined
      perf/x86/amd: Avoid taking branches before disabling LBR
      perf/x86/amd: Support capturing LBR from software events
      perf/x86/amd: Don't reject non-sampling events with configured LBR

Erick Archer (1):
      perf/x86/rapl: Prefer struct_size() over open coded arithmetic

Ingo Molnar (2):
      perf/bpf: Change the !CONFIG_BPF_SYSCALL stubs to static inlines
      perf/bpf: Mark perf_event_set_bpf_handler() and perf_event_free_bpf_handler() as inline too

Kyle Huey (10):
      perf/bpf: Reorder bpf_overflow_handler() ahead of __perf_event_overflow()
      perf/bpf: Create bpf_overflow_handler() stub for !CONFIG_BPF_SYSCALL
      perf/bpf: Remove #ifdef CONFIG_BPF_SYSCALL from struct perf_event members
      perf/bpf: Call BPF handler directly, not through overflow machinery
      perf/bpf: Remove unneeded uses_default_overflow_handler()
      perf/bpf: Allow a BPF program to suppress all sample side effects
      selftest/bpf: Test a perf BPF program that suppresses side effects
      perf: Move perf_event_fasync() to perf_event.h
      perf/ring_buffer: Trigger IO signals for watermark_wakeup
      selftests/perf_events: Test FASYNC with watermark wakeups
