linux-next: build failure after merge of the final tree (uprobestree related)

[Stephen Rothwell]

Hi Srikar,

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

In file included from include/linux/mm_types.h:15:0,
                 from include/linux/sched.h:64,
                 from arch/powerpc/mm/mem.c:21:
include/linux/uprobes.h:174:49: error: 'struct mm_struct' declared inside parameter list [-Werror]
include/linux/uprobes.h:174:49: error: its scope is only this definition or declaration, which is probably not what you want [-Werror]

And many more similar.

Caused by commit 61fafad13005 ("uprobes_xol" - "uprobes: slot allocation").

I have added the following patch for today:

From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Wed, 23 Nov 2011 14:35:01 +1100
Subject: [PATCH] uprobes: declare mm_struct before its use in uprobes.h

Since there is a circular dependency between uprobes.h and mm_type.h
