From 8a87411b649c6082aebea613e84dcb3f174f72fb Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 2 May 2014 17:06:19 +0100 Subject: ARM: 8047/1: rwsem: use asm-generic rwsem implementation asm-generic offers an atomic-add based rwsem implementation, which can avoid the need for heavier, spinlock-based synchronisation on the fast path. This patch makes use of the optimised implementation for ARM CPUs.
