From aef591cd3d1ddccb268f64c836d38382007373c1 Mon Sep 17 00:00:00 2001 From: Waiman Long Date: Thu, 12 Jan 2017 15:27:58 -0500 Subject: locking/spinlocks/x86, paravirt: Remove paravirt_ticketlocks_enabled MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is a follow-up of commit: cfd8983f03c7b2 ("x86, locking/spinlocks: Remove ticket (spin)lock implementation") The static_key structure 'paravirt_ticketlocks_enabled' is now removed as it is no longer used. As a result, the init functions kvm_spinlock_init_jump() and xen_init_spinlocks_jump() are also removed. A simple build and boot test was done to verify it.
