Date: Sat, 20 Jun 2015 21:10:28 -0400 From: Paul Gortmaker <paul.gortmaker@...driver.com> To: <linux-kernel@...r.kernel.org> CC: Paul Gortmaker <paul.gortmaker@...driver.com>, Jonathan Corbet <corbet@....net>, <linux-doc@...r.kernel.org>, Andy Lutomirski <luto@...capital.net> Subject: [PATCH] Documentation/vDSO: don't build tests when cross compiling 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.
