Subject: [PATCH] sched: update the sched-domains debug documentation

    sched: Update the sched-domains debug documentation.

    SCHED_DOMAIN_DEBUG mentioned in the Documentation for sched-domains
    for enabling sched-domains debugging doesn't exist anymore.

    Update the documentation to reflect the correct way of enabling
    sched-domain debugging.

+The sched-domains debugging infrastructure can be enabled by enabling
+CONFIG_SCHED_DEBUG. This enables an error checking parse of the sched domains
 which should catch most possible errors (described above). It also prints out
 the domain structure in a visual format.
