#1452236 — [PATCH 1/2] Documentation: kdump: update maxcpus to nr_cpus

Parameter nr_cpus is used to bring up a SMP dump-capture kernel,
instead of the old parameter maxcpus. This commit update it in
Documentation/kdump/kdump.txt.

IIRC, ARCHes like ppc don't have nr_cpus yet, maxpcus is necessary. So
either you explicitly tell which can use nr_cpus and which can only use
maxcpus option, or drop this patch for now.
