Subject: [RFC][PATCH 4/6] x86, boot: Restrict CFLAGS for hostprogs
Date: Tue, 28 Feb 2012 13:37:23 +0000 [thread overview]
Message-ID: <1330436245-24875-5-git-send-email-matt@console-pimps.org> (raw)
In-Reply-To: <1330436245-24875-1-git-send-email-matt@console-pimps.org>
From: Matt Fleming <matt.fleming@intel.com>
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.
