From: Paul Gortmaker Date: Sun, 21 Jun 2015 01:22:20 +0000 (-0400) Subject: Documentation/prctl: don't build tsc tests when cross compiling X-Git-Tag: v4.2-rc1~125^2~2 X-Git-Url: http://git.cascardo.info/?a=commitdiff_plain;h=f59514b6a8c5ca6dd282881a25e367e20ef4cb68;hp=6a407a81a9abcf6664698b22e70d070605063f7c;p=cascardo%2Flinux.git 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.
