Hi Linus,

After merging the fixes tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

arch/powerpc/kernel/built-in.o: In function `.sys_call_table':
(.text+0xbd00): undefined reference to `.sys_nfsservctl'
arch/powerpc/kernel/built-in.o: In function `.sys_call_table':
(.text+0xbd08): undefined reference to `.compat_sys_nfsservctl'

Caused by commit f5b940997397 ("All Arch: remove linkage for
sys_nfsservctl system call") which also missed parisc.

I will apply this patch for today:

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Mon, 29 Aug 2011 10:38:57 +1000
Subject: [PATCH] remove remaining references to nfsservctl

These were missed in commit f5b940997397 "All Arch: remove linkage
for sys_nfsservctl system call" due to them having no sys_ prefix
(presumably).

Hi all,

Building Linus' tree, today's linux-next build (powerpc allyesconfig)
failed like this:

ld: net/bpfilter/bpfilter_umh.o: compiled for a little endian system and target is big endian
ld: failed to merge target specific data of file net/bpfilter/bpfilter_umh.o

This has come to light since I started using a native compiler (i.e. one
that can build executables, not just the kernel) for my PowerPC builds
on a powerpcle host.

I have switched back to my limited compiler.

Hi Linus,

Today's linux-next initial build (powerpc ppc64_defconfig) failed like
this:

cc1: warnings being treated as errors
arch/powerpc/kernel/module.c: In function 'module_finalize':
arch/powerpc/kernel/module.c:66: error: unused variable 'err'

Caused by commit 5336377d6225959624146629ce3fc88ee8ecda3d ("modules: Fix
module_bug_list list corruption race").

I added the following patch for today:

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Wed, 6 Oct 2010 11:06:44 +1100
Subject: [PATCH] powerpc: remove unused variable

Since powerpc uses -Werror on arch powerpc, the build was broken like
this:

cc1: warnings being treated as errors
arch/powerpc/kernel/module.c: In function 'module_finalize':
arch/powerpc/kernel/module.c:66: error: unused variable 'err'
