[PATCH 23/30] x32: Add rt_sigframe_x32

[H. Peter Anvin]

From: "H. Peter Anvin" <hpa@xxxxxxxxx>

Add rt_sigframe_x32 to <asm/sigframe.h>.  Unfortunately we can't just
define all the data structures unconditionally, due to the #ifdef
CONFIG_COMPAT in <linux/compat.h> and its trickle-down effects, hence
the #ifdef mess.
