Log Message:
Import of SCHED_M2 - the implementation of new scheduler, which is based
on the original approach of SVR4 with some inspirations about balancing
and migration from Solaris.  It implements per-CPU runqueues, provides a
real-time (RT) and time-sharing (TS) queues, ready to support a POSIX
real-time extensions, and also prepared for the support of CPU affinity.

The following lines in the kernel config enables the SCHED_M2:

no options SCHED_4BSD
options SCHED_M2

The scheduler seems to be stable.  Further work will come soon.
