Peter Anvin" <hpa@...or.com> Subject: [PATCH 06/14] x86: add a Kconfig symbol for when relocations are needed From: H. Peter Anvin <hpa@...or.com> We only need to build relocations when we are building a 32-bit relocatable kernel. Rather than unnecessarily complicating the Makefiles, make an explicit Kbuild symbol for this. [ Impact: permits future cleanup ] Signed-off-by: H.
