arm64: Call __show_regs directly
Generic code expects show_regs() to also dump the stack, but arm64's show_reg() does not do this. Some arm64 callers of show_regs() *only* want the registers dumped, without the stack. To enable generic code to work as expected, we need to make show_regs() dump the stack. Where we only want the registers dumped, we must use __show_regs(). This patch updates code to use __show_regs() where only registers are desired. A subsequent patch will modify show_regs().
