From 66c5227ecd3041b0467a091ad81b8d312e572ea8 Mon Sep 17 00:00:00 2001 From: Evgeniy Polyakov Date: Thu, 31 May 2007 13:46:21 +0900 Subject: sh: trivial build cleanups. Several errors were spotted during building for custom config (SMP included). Although SMP still does not compile (no ipi and __smp_call_function) and does not work, this looks a bit cleaner. Some other errors obtained via gcc-4.1.0 build.
