Subject: [4/5] MIPS: Malta: hang on halt
Origin: https://git.kernel.org/linus/37e5c835bbbce4fde11cccc30dfe6c7b853ea964
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.]
