Subject: [PATCH 3.16 037/410] KVM: x86: rename update_db_bp_intercept to
 update_bp_intercept

3.16.57-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Paolo Bonzini <pbonzini@redhat.com>

commit a96036b8ef7df9f10cd575c0d78359bd33188e8e upstream.

Because #DB is now intercepted unconditionally, this callback
only operates on #BP for both VMX and SVM.
