Subject: [PATCH] x86-32: Fix __per_cpu_load relocation
Date: Mon, 26 Jan 2009 08:44:05 -0500 [thread overview]
Message-ID: <1232977445-11815-1-git-send-email-brgerst@gmail.com> (raw)
In-Reply-To: <20090126103243.GA31307@elte.hu>
This patch fixes this error:
WARNING: Absolute relocations present
Offset Info Type Sym.Value Sym.Name
c0a4e07d 00e78001 R_386_32 c0ab0000 __per_cpu_load
Now, __per_cpu_load is a section-relative symbol:
c0aa4000 D __per_cpu_load
c0aa4000 A __per_cpu_load_abs
