The following was seen in linux-next build coverage, which is somewhat unique since it uses powerpc host to cross compile x86: Documentation/vDSO/vdso_standalone_test_x86.c:49:2: error: impossible register constraint in 'asm' make[4]: *** [Documentation/vDSO/vdso_standalone_test_x86.o] Error 1 It probably makes sense to just skip building these tests when we are cross compiling.
