LAZY_SWITCH changes. He pointed out the acpi code sets up an identity
mapping in the current vmspace and that got messed up by the %cr3 being
out of sync with the current page directory. As a workaround, restore
%cr3 across the sleep/resume. A more complete fix would be to undo the
lazy state and clear the pm_active bit from the borrowed pmap, but this
works and people are currently hurting. I'll clean this up.
This is mostly Ian's patch, plus a PAE tweak from me.
that an argument is not a NULL pointer.
Apply various obvious places.
I belive __printf*() implies __nonnull() so it is not needed on functions
already tagged that way.
it attaches to all existing NATM network interfaces in the system
and creates a HARP physical interface for each of them. This allows
us to use the same set of ATM drivers for all ATM stuff. It is
possible to use the same interface for HARP, NATM and netgraph at the
same time.
The output format specifier for the round-trip time in ping6 should be
changed to %.3f instead of %g since %g doesn't accurately represent the
precision of the number being output. In particular, %g truncates trailing
zeroes. 0.01 ms does not mean the same thing as 0.010 ms. Although they
are numerically identical, they do not have the same precision.

go looking for free fragments won't match. Since we never free this, we
can "throw away" the tag. This is very dirty, and needs to be reimplemented
properly, but fixes performance problems with uhci.

o correct active scanning so the first channel is only scanned once and so
per-channel passive mode is properly honored
o expose 802.11 FSM state names so every driver doesn't keep a private copy
o eliminate node parameter to ieee80211_begin_scan; it was not being used
namespace. To compensate for it only being used in the !ECDT case, use
a more robust approach to indicate a device was probed via ECDT by setting
the private ivar to be &acpi_ec_devclass. Without the acpi_MatchHid() call
now, it might have been possible for a non-EC device to have had its magic
match our previous flag.

to EcGpeQueryHandler on to any waiting threads through the softc. Similar
behavior was in the original version.
Also:
* Merge EcQuery into EcGpeQueryHandler to simplify locking
* Hold EcLock from the initial read of the CSR down to the wakeup or
until after the query command has been processed.
* ec_gpebit only needs to be a UINT8
struct vfsconf. This silences a warning, but could also prevent
stack corruption problems if xvfsconf ever became larger than vfsconf.

namespace has been evaluated. Machines with ACPI 2.0 expect this behavior
and have AML which calls EC functions early in the boot process. If the
ECDT is not available, fall back to original probe behavior.
Other minor changes:
* Add GPE bit and GLK usage to the device announcement
* Always use the global lock in the ECDT case, but potentially downgrade to
not using it if _GLK is 0 once the namespace is available. This is
announced with "Changing GLK from 1 to 0"
* Remove the acpi_object_list definitions which were earlier deprecated

and make it work more reliably in a number of cases that have
traditionally been troublesome. The new behaviour is:
1) If the filesystem can be determined by the fsid or device,
or uniquely identified by the mountpoint, then just go ahead
and call unmount(2) using the file system ID.
2) Otherwise use fstatfs(2) to resolve the path into a file system
ID (checking with stat(2) that it is a filesystem root directory).
Case 2 can potentially block if an NFS server is down, but it can
always be avoided by using an unambiguous specification. It handles
all the hard cases such as symlinks and mismatches between the mount
list and reality. For example, if a filesystem was mounted as /mnt
inside a chroot, it will show up in the mount list as /mnt, but now
you can unmount it from outside the chroot with "umount /chroot_path/mnt".
one is already available. This avoids sometimes unnecessary
step of attempting to rebuild the make binary again which may
fail at all if, for example, one has removed his /usr/include
before doing an installworld (to keep /usr/include tidied up).
