KVM: x86: hyper-v: Mention SynDBG CPUID leaves in api.rst (b44f50d8) · Commits · 戴 / test

We forgot to update KVM_GET_SUPPORTED_HV_CPUID's documentation in api.rst when SynDBG leaves were added. While on it, fix 'KVM_GET_SUPPORTED_CPUID' copy-paste error. Fixes: ("x86/kvm/hyper-v: Add support for synthetic debugger interface") Signed-off-by:
