  perf: Drop guest callback (un)register stubs (2021-11-17 14:49:12 +0100)

----------------------------------------------------------------
Peter Zijlstra says:

"Cleanup of the perf/kvm interaction."

Like Xu (1):
      perf/core: Rework guest callbacks to prepare for static_call support

Sean Christopherson (16):
      perf: Protect perf_guest_cbs with RCU
      KVM: x86: Register perf callbacks after calling vendor's hardware_setup()
      KVM: x86: Register Processor Trace interrupt hook iff PT enabled in guest
      perf: Stop pretending that perf can handle multiple guest callbacks
      perf: Drop dead and useless guest "support" from arm, csky, nds32 and riscv
      perf: Add wrappers for invoking guest callbacks
      perf: Force architectures to opt-in to guest callbacks
      perf/core: Use static_call to optimize perf_guest_info_callbacks
      KVM: x86: Drop current_vcpu for kvm_running_vcpu + kvm_arch_vcpu variable
      KVM: x86: More precisely identify NMI from guest when handling PMI
      KVM: Move x86's perf guest info callbacks to generic KVM
      KVM: x86: Move Intel Processor Trace interrupt handler to vmx.c
      KVM: arm64: Convert to the generic perf callbacks
      KVM: arm64: Hide kvm_arm_pmu_available behind CONFIG_HW_PERF_EVENTS=y
      KVM: arm64: Drop perf.c and fold its tiny bits of code into arm.c
      perf: Drop guest callback (un)register stubs
