Subject: [PATCH 0/2] Use static_call for kvm_x86_ops
Date: Mon, 11 Jan 2021 11:57:26 -0500	[thread overview]
Message-ID: <cover.1610379877.git.jbaron@akamai.com> (raw)

Hi,

Convert kvm_x86_ops to use static_call. Shows good performance
gains for cpuid loop micro-benchmark (resulsts included in patch 2).

Thanks,

-Jason
