[PATCH] arch/i386/kernel/signal.o: sparse: cast remove address space ...

[Sam Ravnborg <sam@ravnborg.org>]

Fix sparse warning: cast removes address space of expression
Fixed by declaring relevant pointers in sigframe and rt_sigframe as
__user.
This fixes several sparse warnings in arch/i386/kernel/signal.c
