Subject: [PATCH 0/3] KVM: x86: hyperv: PV IPI support for Windows guests
Using hypercall for sending IPIs is faster because this allows to specify
any number of vCPUs (even > 64 with sparse CPU set), the whole procedure
will take only one VMEXIT.
Same as PV TLB flush, this allows Windows guests having > 64 vCPUs to boot
on KVM when Hyper-V extensions are enabled.
Vitaly Kuznetsov (3):
KVM: fix KVM_CAP_HYPERV_TLBFLUSH paragraph number
x86/hyper-v: rename ipi_arg_{ex,non_ex} structures
KVM: x86: hyperv: implement PV IPI send hypercalls
