Subject: Re: [PATCH 5/6] improve sys_newuname for compat architectures
Updated version to apply without the previous sys_personality patch.
The last patch still applies fine after this one.

From: Christoph Hellwig <hch@....de>
Subject: improve sys_newuname for compat architectures
On an architecture that supports 32-bit compat we need to override
the reported machine in uname with the 32-bit value. Instead of
doing this separately in every architecture introduce a COMPAT_UTS_MACHINE
define in <asm/compat.h> and apply it directly in sys_newuname.
