Subject: [PATCH v2 17/32] KVM: SVM: Wire up ->tlb_flush_guest() directly to svm_flush_tlb()
Date: Mon, 16 Mar 2020 21:52:23 -0700	[thread overview]
Message-ID: <20200317045238.30434-18-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20200317045238.30434-1-sean.j.christopherson@intel.com>

Use svm_flush_tlb() directly for kvm_x86_ops->tlb_flush_guest() now that
the @invalidate_gpa param to ->tlb_flush() is gone, i.e. the wrapper for
->tlb_flush_guest() is no longer necessary.

No functional change intended.
