From f59514b6a8c5ca6dd282881a25e367e20ef4cb68 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Sat, 20 Jun 2015 21:22:20 -0400 Subject: Documentation/prctl: don't build tsc 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/prctl/disable-tsc-on-off-stress-test.c:36:1: error: impossible register constraint in 'asm' Documentation/prctl/disable-tsc-ctxt-sw-stress-test.c:34:1: error: impossible register constraint in 'asm' Documentation/prctl/disable-tsc-test.c:36:1: error: impossible register constraint in 'asm' It probably makes sense to just skip building these tests when we are cross compiling.
