Subject: x86, boot: Correct CFLAGS for hostprogs
From: "H. Peter Anvin" <[email protected]>
commit 446e1c86d51d0823e003a43a2b85c430efce2733 upstream.
This is a partial revert of commit:
d40f833 "Restrict CFLAGS for hostprogs"
The endian-manipulation macros in tools/include need <linux/types.h>,
but the hostprogs in arch/x86/boot need several headers from the
kernel build tree, which means we have to add the kernel headers to
the include path. This picks up <linux/types.h> from the kernel tree,
which gives a warning.
Since this use of <linux/types.h> is intentional, add
-D__EXPORTED_HEADERS__ to the command line to silence the warning.
A better way to fix this would be to always install the exported
kernel headers into $(objtree)/usr/include as a standard part of the
kernel build, but that is a lot more involved.
