From 845adf7266a7ba6970bf982ffd96abc60d2018ab Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Tue, 5 May 2009 21:20:51 -0700 Subject: [PATCH] x86: add a Kconfig symbol for when relocations are needed 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.
