Subject: [PATCH 09/10] KVM: VMX: Drop @invalidate_gpa from __vmx_flush_tlb()
Date: Thu, 20 Feb 2020 12:43:55 -0800 [thread overview]
Message-ID: <20200220204356.8837-10-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20200220204356.8837-1-sean.j.christopherson@intel.com>
Drop @invalidate_gpa from __vmx_flush_tlb() now that it's sole caller
unconditionally passes %true, i.e. "(invalidate_gpa || !enable_vpid)"
will always evaluate true.
No functional change intended.
