From 37e5c835bbbce4fde11cccc30dfe6c7b853ea964 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Wed, 7 May 2014 12:20:59 +0100 Subject: MIPS: Malta: hang on halt 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.
