[PATCH RFC v3 0/9] KVM: allow dynamic kvm->vcpus array

[rkrcmar@redhat.com (Radim Krčmář)]

The only common part with v2 is [v3 5/9].

The crucial part of this series is adding a separate mechanism for
kvm_for_each_vcpu() [v3 8/9] and with that change, I think that the
dynamic array [v3 9/9] would be nicer if protected by RCU, like in v2:
The protection can be nicely hidden in kvm_get_vcpu().  I just had the
split done before implementing [v3 8/9] and presented it for
consideration.

Smoke tested on x86 only.


Radim Kr?m?? (9):
  KVM: s390: optimize detection of started vcpus
  KVM: arm/arm64: fix vcpu self-detection in vgic_v3_dispatch_sgi()
  KVM: remember position in kvm->vcpus array
  KVM: arm/arm64: use locking helpers in kvm_vgic_create()
  KVM: remove unused __KVM_HAVE_ARCH_VM_ALLOC
  KVM: rework kvm_vcpu_on_spin loop
  KVM: add kvm_free_vcpus and kvm_arch_free_vcpus
  KVM: implement kvm_for_each_vcpu with a list
  KVM: split kvm->vcpus into chunks
