Put the extern declarations of the virtualized globals
under VIMAGE_GLOBAL as the globals themsevles are already.
This will help by the time when we are going to remove the globals
entirely.

might do subsequent reads from other providers. This stopped geli (and
probably other classes using g_metadata_store as well) from being put on top
of gvinum raid5 volumes.
Note:
The reason it fails in the gvinum raid5 case is that gvinum will read back the
old parity stripe before calculating the new parity stripe to be written out
again. The write will then fail because the underlying disk to be read is
opened write only.

- Improve code and control flow clarity by invoking hwpmc(4)'s user

if (batt_sleep_ms)
AcpiOsSleep(batt_sleep_ms);
I can't recall why that one was different, so change it
to match the rest.

All ioctl()'s that aren't implemented by pts(4) are forwarded to the TTY
itself. Unfortunately this is not correct for FIONREAD, because it will
give the wrong amount of bytes that are available to read.

On some laptops with smart batteries, enabling battery monitoring
software causes keystrokes from atkbd to be lost. This has also been
reported on Linux, and is apparently due to the keyboard and I2C line
for the battery being routed through the same chip. Whether that's
accurate or not, adding extra sleeps to the status checking code
causes the problem to go away.
I've been running this for nearly six months now on my laptop,
it works like a charm.

error is not EAGAIN. Several sysctls that inspect another process use
p_candebug() for checking access right for the curproc. p_candebug()
returns EAGAIN for some reasons, in particular, for the process doing
exec() now. If execing process tries to lock Giant, we get a livelock,
because sysctl handlers are covered by Giant, and often do not sleep.
Break the livelock by dropping Giant and allowing other threads to
execute in the EAGAIN loop.
Also, do not return EAGAIN from p_candebug() when process is executing,
use more appropriate EBUSY error [1].

devd(8) receiving events from devctl(4) for linkup/link down. This allows
us to do several useful things, including initializing tunnel parameters
and adding routes.
