Cross-architecture equivalent of rdusp(); default is user_stack_pointer(current_pt_regs()) - that works for almost all platforms that have usp saved in pt_regs. The only exception from that is ia64 - we want memory stack, not the backing store for register one. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
