Subject: linux-next: build failure after merge of the uprobes tree

Hi Srikar,

After merging the uprobes tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from include/linux/compat.h:18:0,
                 from arch/x86/include/asm/ia32.h:7,
                 from arch/x86/include/asm/sigframe.h:17,
                 from arch/x86/kernel/asm-offsets.c:16:
arch/x86/include/asm/compat.h:238:20: error: redefinition of 'is_ia32_task'
arch/x86/include/asm/thread_info.h:272:20: note: previous definition of 'is_ia32_task' was here

Caused by commit 081c056eccf3 ("x86: Move is_ia32_task to
asm/thread_info.h from asm/compat.h") which added the function to
asm/thread_info.h but did not remove it from asm/compat.h.  The version
of this patch that is in the tip tree is correct (but that is not in
tip's auto-latest branch (and hence linux-next) today).

I would have used the uprobes tree from next-20130309, but trying that
produced a large number of conflicts, so I just dropped the uprobes tree
for today.
