Subject: [PATCH] Fix compat uname machine
Date: Thu, 15 Apr 2010 18:28:33 +0200	[thread overview]
Message-ID: <m2wrw8he8e.fsf@igel.home> (raw)

Mask off personality flags when checking for PER_LINUX32.

Signed-off-by: Andreas Schwab <schwab@linux-m68k.org>

On ppc64 you get this error:

$ setarch ppc -R true
setarch: ppc: Unrecognized architecture

because uname still reports ppc64 as the machine.

Andreas.
