From d40f833630a1299fd377408dc8d8fac370d621b0 Mon Sep 17 00:00:00 2001 From: Matt Fleming Date: Tue, 28 Feb 2012 13:37:23 +0000 Subject: [PATCH] x86, boot: Restrict CFLAGS for hostprogs Currently tools/build has access to all the kernel headers in $(srctree). This is unnecessary and could potentially allow tools/build to erroneously include kernel headers when it should only be including userspace-exported headers. Unfortunately, mkcpustr still needs access to some of the asm kernel headers, so explicitly special case that hostprog. Cc: H.
