X-Git-Tag: firefly_0821_release~24513^2~6 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=0e670685e4925930000a678c74eb1cbf23b415fa;p=firefly-linux-kernel-4.4.55.git 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.
