This actually causes a build failure on a sparc32 defconfig build:
`rpcauth_remove_module' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o
I applied the following patch for today:
From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Wed, 29 Sep 2010 14:07:07 +1000
Subject: [PATCH] sunrpc: fix up section mismatch
Fixes:
`rpcauth_remove_module' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o
