If anyone has any objections, please let me know. ------------------ From: "H. Peter Anvin" commit 446e1c86d51d0823e003a43a2b85c430efce2733 upstream. This is a partial revert of commit: d40f833 "Restrict CFLAGS for hostprogs" The endian-manipulation macros in tools/include need , 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 from the kernel tree, which gives a warning. Since this use of 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.
