When the system is halted it makes little sense to reset it. Instead, hang by executing an infinite loop. [ralf@linux-mips.org: Remove printk from mips_machine_halt() - this is not the place to communicate with the user.] Suggested-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Paul Burton <paul.burton@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/6906/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
