As it was decided not to export struct pt_regs to userspace, struct sigcontext shouldn't be using it either. The pt_regs struct for OpenRISC is kernel internal and the layout of the registers may change in the future. The struct user_regs_struct is what is guaranteed to remain stable, so struct sigcontext may use that instead. This patch removes the usage of struct pt_regs in struct sigcontext and makes according changes in signal.c to get the register layout right. The usp field is removed from the sigcontext structure as this information is already contained in the user_regs_struct.
