ndesaulniers@google.com 1011745073 drm/amd/display: add -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines ... arch/x86/Makefile disables SSE and SSE2 for the whole kernel. The AMDGPU drivers modified in this patch re-enable SSE but not SSE2. Turn on SSE2 to support emitting double precision floating point instructions rather than calls to non-existent (usually available from gcc_s or compiler_rt) floating point helper routines.
