From f1898f6be9a2e3690fb62d8307849b86a89cc36c Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Mon, 6 Aug 2012 18:43:42 +0100 Subject: ARM: 7484/1: Don't enable GENERIC_LOCKBREAK with ticket spinlocks Now that ARM has implemented its spinlocks with tickets we don't need to use the generic lockbreak algorithm. Remove the Kconfig from ARM so that we use the arch_spin_is_contended() definition from the asm header. This also saves a word in each lock because we don't need the break_lock member anymore.
