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.

- 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.
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.

Thanks <ad> for the benchmarks!
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.
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.
- Replace most panic() checks with KASSERT();
- msgrcv1: Improve readability;
- Remove #ifdef ENOMSG;
No function changes of the interface are intented.
- 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.
