From 836624619b98535079053920a29a7e474ac17cbc Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 28 Sep 2007 16:04:49 +0900 Subject: sh: Conditionalize gUSA support. This conditionalizes gUSA support. gUSA is not supported on SMP configurations, and it's not necessary there anyways due to having other atomicity options (ie, movli.l/movco.l). Anything implementing the LL/SC semantics (all SH-4A CPUs) can switch to userspace atomicity implementations without requiring gUSA. This is left default-enabled on all UP so that glibc doesn't break. Those that know what they are doing can disable this explicitly.
