Subject: [PATCH 3/4] KVM: VMX: Rename RDTSCP secondary exec control name to insert "ENABLE"
Date: Wed, 23 Sep 2020 09:50:47 -0700	[thread overview]
Message-ID: <20200923165048.20486-4-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20200923165048.20486-1-sean.j.christopherson@intel.com>

Rename SECONDARY_EXEC_RDTSCP to SECONDARY_EXEC_ENABLE_RDTSCP in
preparation for consolidating the logic for adjusting secondary exec
controls based on the guest CPUID model.

No functional change intended.
