Subject: Re: [PATCH -v5 5/5] Make reboot_cpuid a kernel parameter.
Date: Wed, 17 Apr 2013 12:59:57 -0700 [thread overview]

It is also worth noting that the documentation says reboot=s[mp]#
whereas in fact only reboot=s# parse correctly. I consider this to be a
bug.
If we centralized the parser, we could take a string like
"reboot=bios,smp32,warm"
and parse it into:
reboot_cpu = 32
reboot_mode = "bw"
... and pass the information in that form to the arch layer. I don't
think we can do more parsing at that in the main kernel.
