Build breakage due to latest ARM fixes

[Olof Johansson]

Russell,

Looks like you sent up some fixes to Linus that broke one of the atmel
configs (CONFIG_MMU=n):

commit 48be69a026b2c1 ARM: move signal handlers into a vdso-like page

seems to have caused it:

arch/arm/kernel/signal.c: In function 'setup_return':
arch/arm/kernel/signal.c:413:25: error: 'mm_context_t' has no member
named 'sigpage'

I see it with at91x40_defconfig.
