Bug Description


I would like cherry pick the following commits from the kernel 4.5 to 4.4 (Ubuntu 16.04):

        affddff powerpc/powernv: Add a kmsg_dumper that flushes console output on panic
        c88c5d4 powerpc/powernv: Fix OPAL_CONSOLE_FLUSH prototype and usages

This is going to help debugging kernel panic.
