    openrisc: don't use pt_regs in struct sigcontext · d7cb6667
    Jonas Bonn authored
    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.
