09fda47045 Waste a bit of kernel VA space (who cares?) and speed up crash dumps 
significantly by writing larger chunks with one (polled) command.

ae7946d0ba - Mention SCHED_M2 in the recent changes; 
- Scheduler works will be in 5.0 release;
- Mention NUMA in the roadmap;

P.S. Everyone: please sync the ROADMAP with the
reality and the works you do.

a21233e46b 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.

2e75cc0f7b - Do not allow a 'critical-{max,min}' property in battery 
sensors (those that contain the 'want-percentage' object on its
  dictionary), the 'critical-capacity' prop must be used instead.

- When setting a 'critical-{max,min}' property check if the value is
  higher than the 'max-value' or lower than the 'min-value' on its
  dictionary, raise an error if it's true.

3a5409e4eb Fix an off-by-one error in handing mal-formed modifiers. 
The issue seems to have been present for some time, only showed up
when running unit-tests on SunOS.
Make sure we get an error message, but otherwise behave as before.

862626dd09 two new hacks: 
- include <stdbool.h> so bool is available _KERNEL for sys/condvar.h
- include <sys/mutex.h> before defining _KERNEL so it won't try to
  include <machine/intr.h> which isn't available to userland.

fixes builds on sparc64.
