[PATCH] uml: fix lvalue for gcc4

      Russell King <rmk+lkml@arm.linux.org.uk>

This construct is refused by GCC 4, so here's the (corrected) fix.  Thanks to
Russell for noticing a stupid mistake I did when first sending this.

As he noted, the code is largely suboptimal however it currently works, and
will be fixed shortly.  Just read the access_ok check on fp which is NULL, or
the pointer arithmetic below which should be done with a cast to void*:

 	frame = (struct rt_sigframe __user *)
 		round_down(stack_top - sizeof(struct rt_sigframe), 16) - 8;

The code shows clearly that has been taken from
arch/x86_64/kernel/signal.c:setup_rt_frame(), maybe in a bit of a hurry.
