From 6ae11028a62b2f82ee283392a84f33da599a81e7 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Wed, 12 Mar 2014 17:11:00 +0100 Subject: arch,alpha: Convert smp_mb__*() to the asm-generic primitives The Alpha ll/sc primitives do not imply any sort of barrier; therefore the smp_mb__{before,after} should be a full barrier. This is the default from asm-generic/barrier.h and therefore just remove the current definitions. Signed-off-by: Peter Zijlstra Acked-by: Paul E.
