x86: remove always-defined CONFIG_AS_SSSE3
CONFIG_AS_SSSE3 was introduced by commit 75aaf4c3e6a4 ("x86/raid6: correctly check for assembler capabilities"). We raise the minimal supported binutils version from time to time. The last bump was commit 1fb12b35e5ff ("kbuild: Raise the minimum required binutils version to 2.21"). I confirmed the code in $(call as-instr,...) can be assembled by the binutils 2.21 assembler and also by LLVM integrated assembler. Remove CONFIG_AS_SSSE3, which is always defined. I added ifdef CONFIG_X86 to lib/raid6/algos.c to avoid link errors on non-x86 architectures. lib/raid6/algos.c is built not only for the kernel but also for testing the library code from userspace. I added -DCONFIG_X86 to lib/raid6/test/Makefile to cator to this usecase. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Jason A.
