From 0e670685e4925930000a678c74eb1cbf23b415fa Mon Sep 17 00:00:00 2001 From: Stuart Menefy Date: Fri, 2 Nov 2007 12:14:09 +0900 Subject: [PATCH] sh: Fix optimized __copy_user() movca.l usage. movca.l is restricted to SH-4 and up only, though compilers that are unable to support ISA tuning (especially older versions of binutils) will happily compile in the bogus opcode on older parts. Conditionalize it to fix SH-3 regressions noted by Kristoffer.
