From ddf1d169c0a489d498c1799a7043904a43b0c159 Mon Sep 17 00:00:00 2001 From: Tim Chen Date: Tue, 21 Jan 2014 15:36:22 -0800 Subject: locking/mcs: Allow architecture specific asm files to be used for contended case This patch allows each architecture to add its specific assembly optimized arch_mcs_spin_lock_contended and arch_mcs_spinlock_uncontended for MCS lock and unlock functions.
