Subject: [PATCH] Fix compat uname machine

Mask off personality flags when checking for PER_LINUX32.

Signed-off-by: Andreas Schwab <schwab@...ux-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.
