bbaa4c8c80 Cache vnode member variables necessary for operations after the 
userspace call, namely our private mount structure, in the activation
record.  This avoids problems in situations where the userspace
file server happens to die during our upcall and the vnode is
forcibly reclaimed before we roll back to the current stack frame.

7ade6d03ad Fix the problems described in: 
http://mail-index.netbsd.org/current-users/2007/07/16/0012.html

- Introduce sme_class into the sysmon_envsys struct to specify a
  class; currently there are two classes: SME_CLASS_ACADAPTER and
  SME_CLASS_BATTERY.

- Add a new envsys event: PENVSYS_EVENT_LOW_POWER that is reached when
  all SME_CLASS_BATTERY devices are in CRITICAL/LOW state and there's not
  any SME_CLASS_ACADAPTER connected.

- Add the 'low-power' event into the sensor_battery script that will
  shutdown the system gracefully via 'shutdown -p'. If powerd(8) is
  not running, cpu_reboot(9) with RB_POWERDOWN is used.

- Make acpiacad(4) a SME_CLASS_ACADAPTER device and acpibat(4) a
  SME_CLASS_BATTERY device.

Update the documentation accordingly to these changes.

ae7946d0ba - Mention SCHED_M2 in the recent changes;

- 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.
